WHAT YOU ARE SAYING
More on ‘Why the dropout rate’? Dear Dave I was very interested to read your editorial (Dive 166) on diver drop out rates of over 90%. As a recent learner I wonder if it is actually because the trainees do not feel that they are competent enough to dive safely at the end of their training. I wonder this because despite having completed my open water, advanced open water, rescue diver, and 60 dives, I still am not a "confident" diver. Add to this a dive where I was Iucky not to injure myself through a rapid ascent which made me question whether I should be diving at all.
T
advice re their children taking up scuba diving I always say, get them to become competent snorkelers first!
hanks Pete. You raise a point I have continually discussed with divers over many years. The point being: How comfortable is a person in the water/ ocean before they learn to scuba dive?
They learn to understand the ‘moods’ of the ocean - its strength, currents, surf, bad and good visibility. Also, more importantly, they build a confidence in their body’s ability to recognize potential problems in the water environment.
But that advice does not work when people just want to learn to scuba dive. Some I’m sure, treat it as a box to tick off their bucket list, a bit like doing a parachute jump! The training agencies are fully aware of this sort of demand and have course products that cater for it.
On a positive note. Although I am Christchurch based I have had the opportunity to do a number of dives with the Dive Wellington club. This is an excellent opportunity to build experience in a benign environment with experienced divers and instructors without it costing too much. Regards Pete Rivers
who is in charge of the police National Dive Squad continually tells us too many divers carry excessive lead weight. You should always slowly swim to the surface, not push a button to get there! No more rapid ascents! And you should be able to float easily on the surface with NO air in your BC. The training agencies teach this!
Diving is a fantastic sport and your confidence will improve as you log up more dives. But having already done …Do not … get caught up in the 60 dives I am wondering what was added expense of doing another course in the belief it will make (you) the standard of training you received?
I recall the late Dr Tony Slark, a New Zealand Navy doctor (the Navy recompression chamber in Devonport, Auckland is named after him) tell me that the best divers to train for the Navy were ex spearfishermen. People who participate is sports such as underwater hockey, surfing and water polo also have a head start in becoming competent scuba divers. And when, over the years, parents have asked me for
4 Dive New Zealand | Dive Pacific
Why are we in this position? The Open Water portion of the course is too compressed... I did four dives over two days to a maximum depth of eight metres to get my Open Water qualification. Did I have reliable control of my buoyancy at the end of this? Definitely not. I'm still working on it! I am one of the lucky ones. I have my own boat and good gear. Another hurdle for those who don't.
Both my children have since
Back in the day, most divers were competent snorkelers/spearfishermen before they took up scuba. Snorkleling/ spearfishing gives a person a solid base to build from, and the strength of this base is directly proportional to the amount of TIME they spend in the water/ocean.
learnt to dive this year and have similar feelings to mine. We are all persevering (carefully) only because we truly love it. I suspect that without this love it would be logical not to continue!
more comfortable in the water. Do a course by all means when (you) are comfortable… As you have intimated, many people become certified as Open Water divers in a VERY short time with limited TIME in the ocean and naturally they can feel very uncomfortable breathing underwater with all the equipment strapped to their body. And they may never reach a point where they are comfortable, so they stop diving. A further point to think about is If you are correctly weighted, you will hardly need to put air into your BC when on the bottom. Senior sergeant Bruce Adams
Do not let your children get caught up in the added expense of doing another course in the belief it will make them more comfortable in the water. Do a course by all means when they are comfortable. These days a person can throws dollars at doing courses and become an instructor in little over a year. But you have to ask, are they really experienced? Its great you are diving with the Dive Wellington club. They are a great bunch of guys and ladies and YES you will learn heaps. I wish you and your children a life time of diving adventures.

Nature can rebound, given a chance! f you live in New Zealand, you really could not complain about the stunning weather we have been having. Dive shops have been having a fantastic entry to their prime summer season. Over this period I enjoy getting out for my once a year adventure spearfishing off the East Coast of the Coromandel Peninsula, although it is rather sobering to see how the fish population has decreased since I first arrived in New Zealand in 1970. Then, I was a member of the Reefcombers Spearfishing club. Some of the members were national champions. Our playground was the Alderman Island 20.8 kms off the beautiful town of Tairua.
the coastline ended up in the “box” which was at the end of a 300 metre net out from the coast. I tried to Google about these nets being used in New Zealand. No luck. This year I had time to recall those amazing times as I was diving Richard’s Rock off the Mercury islands with my son in-law Tim in the search of a king fish to feed the family. Visibility was ‘dusty’ but eventually out of the gloom about six kingies came in for a look. How things have changed!
must be getting desperate when it encourages the harvesting of reef fish many of which cannot be caught on a hook. One of the most in-your-face effects of fewer reef fish such as crayfish and snapper is the proliferation of kina barrens. Kina numbers can explode due to a lack of their natural predators keeping their numbers in check.
From Richard’s Rock we worked the shore line for a snapper or butter fish and in the end we did ok with one kingie, a kahawai and a few butter fish. All we needed to feed three families.

The Award recognizes individuals or groups who have made significant and lasting contributions through research, practice, or advocacy to underwater heritage, maritime archaeology or maritime history.
Edith and Lynton made an amazing team. Their dedication to researching New Zealand’s shipwrecks was nothing but extraordinary. With fellow NZUHG member Keith Gordon they published the 8th edition of the New Zealand Shipwreck book. Within its 576 pages over 530 wrecks are recorded! Edith and Lynton went on to publish two companion books to further record new wrecks and information later uncovered. They were a team of two very sharp minds, worthy joint recipients of the 2018 Award. Dave Moran, Vice President, NZUHG www.underwaterheritage.co.nz

The benefits of limiting the take were demonstrated to me in Tairua. Due to the fishery collapsing, all the commercial cray boats have left the area except one. Guess what? Divers are seeing more crays and the remaining commercial guy caught his quota easily. Wade told me of an amazing recovery of the marine biomass in Matauri Bay where a Maori rahui has been in place for two years. The kina barrens have disappeared. Crays and snapper are plentiful. The recovery has been so dramatic that the local iwi is considering keeping it in place. They are witnessing the joy of their people NEW

Crayfish... Give us a fair crack
A
s we look forward to some late summer sessions in the water it is only natural our thoughts should turn to the delicacies hiding in the depths below. Crayfish is on the top of many people’s wish list, to say thanks to someone special, or for sharing with the family. Treasure your thoughts because in many parts of Aotearoa depletion means they will remain just that, a wish and a dream.
limit. Fortunately some sanity now prevails. Thanks to our collective efforts the Minister cut the CRA 2 Total Allowable Commercial Catch (TACC) by 60% in April last year. This ought to have translated into fewer crayfish pots around inshore areas close to your holiday spot this past summer. In 2018 LegaSea was pushing for a total closure of CRA 2 so that
Currently we have a statutory body that directs the crayfish science and management processes, and then provides advice to the Minister on catch settings. Members of the National Rock Lobster Management Group are appointed by the Minister - none of the current members
…In two South Island areas and in the Gisborne to East Cape area commercial fishers are permitted to take crayfish smaller than the minimum legal size..… report to the public on what goes on in the discussions behind closed doors leading to these settings. And without open public scrutiny the management and policy advice heeded by the Minister since the 1990s has continued to decline to new lows. For example, in two South Island areas and in the Gisborne to East Cape area commercial fishers are permitted to take crayfish smaller than the minimum legal size. But despite being a valuable quota species, we the public are not allowed to know how many of these undersized fish are being taken. The numbers are not reported openly. Further north in the Hauraki Gulf and eastern Bay of Plenty, the CRA 2 stock has become so depleted that professional harvesters were dropping almost 600,000 pots a year and they still could not catch their allowable

it could rebuild with no disturbance from humans; after all we collectively are the problem. The fishery’s management is also a problem because it is lacking in common sense. The TACC has been cut by 60% and the overall recreational allowance has been reduced by 76%. A recent management review discussed halving the daily bag limit and introducing telson clipping to identify recreational catch, by mid 2019. In our submission we supported the bag limit reduction in the interests of rapidly rebuilding the crayfish stock, but the rationale for telson clipping is emotive and driven by commercial interests rather than evidence-based. But altering catch and daily bag limits for crayfish across large and diverse areas creates the illusion that this is an appropriate management strategy
while ignoring the issues of leadership, policy and localised depletion. At ground level we cannot continue the charade that the Rock Lobster Management Group is representative of public interests. The Minister must fulfil his statutory obligations to provide for the foreseeable needs of future generations. If we are to realise the full potential from our fisheries and give ordinary Kiwis a fair crack at gathering a crayfish for that special occasion we must do better. The status quo is not acceptable.

What first got you interested in underwater photography? I always had a passion for photography and combining it with my passion for the marine environment was a natural progression. What is that attracts you to the ocean? It’s what I study and admire. We are able to find something unusual or unique on almost every trip out… there aren’t many environments out there where you can do that! What sort of equipment do you use in your photography? Well, while travelling around California recently, we got absolutely every last bit of camera gear stolen from our vehicle. It was a disaster… so I am currently in the process of replacing this very expensive gear! My new gear will be a Nikon D850 in a Nauticam housing with twin Inon strobes. My main macro lenses are the 60mm and 105mm micro and for wide, I use the 15mm Sigma fish eye. This set up is a beautiful bit of kit and widely regarded as the best available for underwater photography. It doesn’t come cheap though!

What is the most difficult photography project you’ve undertaken? And the most rewarding? It’s probably one and the same thing. Chasing paper nautilus was our first New Zealand Geographic project and it was a toughie! Paper Nautilus are almost never seen alive in New Zealand so we had to think outside the box to get the images. It involved novel diving methods as well as lots of late/ all night adventures off the Northland coast.
Formidable defences
Where’s your favourite spot? Definitely the Poor Knights marine reserve. It’s such a stunning place and we can find rarities or species new to New Zealand on almost every trip. There is a real chance of photographing something no one has ever seen here before. Where’s your next big underwater photography adventure taking you? We have several projects on the go in New Zealand. The 2000 year-old sunken forest in Lake Waikaremoana, ocean flotsam and plastics, seagrass meadows and dune lakes. So plenty to keep us busy. Overseas, we have our eye on Lord Howe Island and British Columbia. What would you most like to photograph that so far eluded you? There are so many… at the moment, we are focusing on the open ocean, so species like Oarfish, Leatherback, tripod fish are all high up our list. Any tips for budding beginners? Get out there… so many of the cool things we find are purely because of time on the water. If you’re not out there, you won’t see it!

Honda National Spearfishing Champs brilliant success Beach start at Moa Pont
Report by Darren Shields, President, Spearfishing NZ
T
his year’s Honda Marine National Spearfishing Champs was held in Wellington and, as always, weather played a big part. Robin Thornton put up his hand to be champs director and did an outstanding job. Honda Marine came on as principal sponsor. A big thank you to them. The Junior’s and Women’s were postponed from Wednesday to Thursday due to weather, and held at the North End of Kapiti Island in stunning conditions. But as always in that area, plenty of tide. Viz was not great but at the end of the day Josh Bird showed his

and Graham Mackereth a very close second, and Paul Best and Jackson Shields third.
The Women’s was won by Alex Edwards who also won the Junior Women’s.
Day Two was held at Moa point with no boats required – the beach start there a first in many years. The zone was Barretts reef right around to include Lyall Bay. A group of the top teams discovered a reef out wide off the airport where some very nice fish were taken.
The under 10 division went to Eli Herbert, and the under 16’s by Tyler Maugham. Day One of the Men’s Open was held on the South End of Kapiti Island, and again the weather was favourable. Dave Mullins along with Mal Bird were the hot favourites with their local knowledge. And so the results proved with Dave and Mal first, Julian Hansford Junior Women's Spearfishing Champ: Alex Edwards
Only three kingfish were speared during the whole event, all from the South Coast with Spencer George Hall taking the biggest. Day Two’s results were a mirror of Junior Spearfishing Champ: Alex Edwards with champs director Robin Thornton

What should you do when a shark shows up?
with Jackson Shields
W
ith summer in full flight and the water temperature getting over 18 degrees, shark encounters can become much more common. This is not about to change any time soon, with the numbers of some species increasing, and as they become more comfortable interacting with humans. In the upper north island Bronze Whalers are the most common and cause the most tension for spearfisher people. They can become pretty territorial, and ‘friendly’. The apparent increase in Bronze Whaler numbers is not bad; typically it’s a sign of a healthier fishery. Because, no matter where you go in the world, if there are a lot of sharks, there are a lot of fish, resulting in a healthy ecosystem. So embracing and learning how to reduce problematic encounters with them is the best approach. There are many techniques and pieces of equipment I use to minimize the risk of a shark eating my fish or otherwise causing me problems. Common sense normally prevails when dealing with Bronze Whalers, and with the other common sharks we may come across like Makos and Seven Gills. I will stick to Bronze Whalers as they tend to be a main culprit.
Guideline 1: Fish selection Now this is a really easy one and probably the most effective way of reducing shark problems. Certain fish tend to attract unwanted attention and be a favourite on a Bronze Whaler’s menu. Now this may break a lot of spearo’s hearts but Kingfish and sharks go hand in hand these days, sometimes literally. 14 Dive New Zealand | Dive Pacific
One of many Bronze Whalers we see at Little Barrier
You will often get a Bronze Whaler or two in convoy with a school of Kingfish waiting for a spearo to make an easy meal for them. Don’t fall into their trap!
Another favourite for sharks is the humble butterfish which is the most popular fish speared. It pays to get butterfish out of the water as soon as possible after spearing it or otherwise you can leave a stringer
…This may break a lot of spearo’s hearts but Kingfish and sharks go hand in hand these days, sometimes literally… Maybe a better option is to steer away from shooting a Kingfish, especially in popular areas where there is known to be high fishing or spearing traffic and where sharks are a known presence. An alternative could be to find a different spot, where there is less known pressure and where the sharks haven’t become accustomed to spearfishers. The Bronze Whalers’ behaviour has been taught to them; they are learning all the time and have figured out that the firing of a speargun is like a dinner bell for them. You may get away with spearing the first fish but the next may explode in chaos.
of ‘lollipops’ for any resident Bronzies. Strangely enough fish like Snapper, John Dory and Boarfish don’t win much attention from sharks and when spearing them I have never really experienced any incidents.
Guideline 2: Diving location This has already been covered a bit in the fish selection section and though, obviously, sharks have tails and can swim anywhere in the ocean, these days there are common spearing grounds that are known for Bronze Whaler

problems. If you are not comfortable with dealing with them, it may pay to avoid these spots. This is not a foolproof solution but would certainly be a step in a safe direction. For example, I want to go shoot a kingfish. Do I go dive the Outpost at Leigh where it is common knowledge the Bronze Whalers can get aggressive with fish in the

the upper hand.
This is one of the most useful pieces of equipment these days for looking after your catch and keeping sharks away from it.
When encountering a shark it’s important to be confident. The shark can sense how you feel and will respond to your movements. Try keeping eye contact with them and making your movements calm and measured.
No fish in the water typically results in less attention from sharks. The Wettie float boat does this. The float won’t sink and will keep your catch out of the water and with it any smell of fish. It’s

Don’t fall into their trap!… water and are well accustomed to meeting spearos? Or I can try a new area along the coast, where I will likely be met with less resistance from sharks? I have dived along that part of the coastline extensively and there are other areas to dive where I definitely get less attention from sharks while still encountering plenty of fish.
proven extremely effective in sharky areas and will save most people a lot of hassle.
Guideline 4: Confidence Lots of people ask me whether they will see a shark when spearfishing and my answer is often yes. We will always have interactions with sharks since we are in their environment and where they have
Often, if a shark takes too much interest in me, I will swim towards it, to ward it off. But if a shark becomes erratic in its movements its typically best you leave the water. However if it’s simply cruising around just enjoy the experience, and keep an eye on it. Note that I have called these guidelines. They are not rules, but just suggestions that have worked for me. Sharks are not to be feared but they are to be respected. Simply killing them will not fix the relationship between us spearos or other divers and sharks. Learning how to be with them in the water, and to get out when necessary, is far better.

Tahiti, richest aquarium on earth
P
Marine environment
roudly displayed on the bodies of Tahitians, you’ll find manta ray, shark, whale and sea turtle tattoos that tell the story of a people defined by the sea.
The crystal-clear waters of The Islands of Tahiti are home to more than 1,000 species of fish with an unmatched variety of colour, size and shape. The smallest fish are often the most colourful and prefer the coral gardens and shallow depths of lagoons, while larger species enjoy the bustle of life in the inlets and reef complexes and beyond, out in the open sea.
Divers come from around the world to experience these sacred sea creatures, which, in The Islands of Tahiti hold a place of reverence among the gods. It’s only natural that the sea around these islands is both figuratively and literally a clear blue heaven on earth. The warm waters that surround The Islands of Tahiti teem with life from flirty clown fish to ever-present sharks, to awe-inspiring humpback whales which arrive between July and November.
The combination of canyons, caverns and coral beds provides a multitude of nooks and crannies for marine life.
A 4 million km² natural aquarium
Because of its exceptional biodiversity, scientists consider the French Polynesian sea zone to be the “richest aquarium on earth”.
When you’re ready to do some diving and snorkelling, the heavens await. There are dozens of unique dive sites around each island and atoll and expert certified dive operators will take care of all the details.
In 2000 the entire region was classified as an Exclusive Economic Zone (EEZ), a wildlife sanctuary where, among other things, drift fishing is prohibited, earning French Polynesia top honours from the WWF (World Wildlife Fund).
Dives and other activities can be arranged in advance by your Preferred Travel Professional or through your resort or cruise ship.

4 tips for beginner Freedivers When it comes to exploring a new challenge like freediving, it’s wise to know a few tips and tricks to get you started. We reached out to PADI Freediver Instructor Trainer and World Champion freediver, Mandy Sumner to get her expert advice for those ready to experience the peace of the underwater world on a single breath. As told by Mandy Sumner
1. Never Dive Alone This is the number one and most important rule in freediving, or any time you’re in the water for that matter. The buddy system is very important and should never be disregarded. It’s essential to watch out for each other, to learn to be aware of the safety of each other, in every dive shallow or deep, and of course everything is always more fun to share with someone or a group of people! You will learn the reasons for never diving alone in the PADI Freediver course.
2. Take the PADI Freediver course You will learn what your body has the capability for, and of course the safety aspect of the sport, which
18 Dive New Zealand | Dive Pacific
is indispensable. Taking a course will introduce you to the basic elements of the sport in a step by step manner which will build your confidence in freediving.
3. Relax Relaxation is the key to freediving. Deep, slow, calm breaths help lower your heart rate so your body will conserve oxygen. Every tense muscle uses heaps of oxygen and energy. You will learn how to relax your body through different breathing and relaxation techniques in freediving courses and clinics.
dives is with the use of visualization. Visualize happy things and peaceful surroundings and your mind will automatically relax your body and lower your heart rate. Visualization can be used pre dive as well as during your dive. For me, when I am competing, I will visualize step by step how I want my dive to go before I even get in the water. When I am in my dive, if I find myself getting tense, I say a little mantra or sing a song in my head, and that helps me relax again. Different things work for different people, but some type of visualization will help before and during your dives. Remember, freediving is for everyone! You don’t need to be an athlete to enjoy freediving.
4. Visualize
The sport is more about relaxation, mind set and technique, than it is about strength – and these are just some of the skills you will develop throughout the PADI Freediver course.

Can a leopard seal change it's resident status? A
leopard seal that has made the balmy waters around Auckland home has prompted a NIWA scientist to campaign for her to be made a New Zealand citizen. Owha has been a familiar site around the Waitemata Harbour for about six years. She likes marinas, sleeps on pontoons, and has recently been spotted wallowing among the mangroves. Dr Krista Hupman, a NIWA cetacean biologist, says the species is now so common in New Zealand waters it needs reclassifying. “Leopard seals are known as a vagrant species meaning New Zealand is well outside their normal range. But despite originating in Antarctic, their numbers keep increasing here and do not always return to Antarctic waters,” she says. Dr Hupman says the status of the species needs to be changed from Vagrant to Resident. The seals have always been described as a solitary Antarctic species and second only to killer whales on the list of Antarctica’s top predators. Dr Hupman and the team at
20 Dive New Zealand | Dive Pacific
LeopardSeals.org has several scientific papers on leopard seals waiting publication which show the species is in fact a Resident in New Zealand waters. In the past two years the team at LeopardSeals.org has put together a database of 2500 sightings of about 170 animals seen all around New Zealand. Some date back to the 1860s. Owha is very easy to recognise. She has two distinctive parallel marks on the right side of her back and a v-shaped scar on the left side of her mouth. She has been spotted at Auckland’s Westhaven Marina, Great Barrier, Waiheke and other Hauraki Gulf islands and as far north as Marsden Cove, Whangarei.
Krista Hupman
Dr Hupman says sightings and photographs of the animals are crucial. “The way we identify and track individual movements over time is by photographing their spot patterns from as many angles of their body as possible. Their spots are like a fingerprint – each seal’s patterning is unique."
To report a leopard seal sighting:
Call 0800 LEOPARD (0800 5367273) – record the date, time and location and if possible, take a photograph. Leopard seals are known to be aggressive so should not be approached.

Eimear Egan, eel earbone detective
Now Dr Egan, a NIWA freshwater ecologist based in Hamilton is studying eels, both the longfin and shortfin species. The eels spend part of their life in marine and coastal environments and once they reach sexual maturity in freshwater they migrate to the western Pacific Ocean to reproduce. Resulting lar vae are transported by ocean currents back to New Zealand’s coastline where they develop into glass eels which are up to 7cm long. Dr Egan and her team are studying the ear bones of these glass eels to learn more about their spawning locations and lar val oceanic movements.
“They tell us about their growth, their spawning and hatching dates, about the chemistr y of the environment they live in, about their diet and movement. And because of that daily layer we can potentially figure out what routes the lar vae took to get to the New Zealand coastline.”
Eimer Egan dispatches an eel trap
“Longfin eels are only found in New Zealand, and they are at risk and declining. At the moment, we don’t really have a good understanding of their early life histor y including locations of spawning grounds and lar val migration routes. That’s where examining glass eel ear bones comes in.
One technique the team will use involves polishing the ear bones by hand until the daily rings become visible. “We can interpret distinct rings, or check marks, that coincide with when the lar vae first feed and when P Athey C Ichange F I Cfrom NEW

lar vae into glass eels. We can measure the distance between rings to figure out daily growth rates, and count the rings to estimate age and the date the lar vae hatched.” The second technique involves using chemistr y to estimate the temperatures the lar vae have experienced at sea. Dr Egan is hoping analysis of the eel tissue using compound specific stable isotopes of amino acids will help pinpoint where in the western Pacific Ocean the lar vae might have come from. Glass eels arrive at the mouths of rivers in pulses, waiting for suitable conditions to enter. During the early part of the season, they tend to migrate into rivers on the incoming tide, especially on the spring tides of new and full moons or after heavy rainfall. There is evidence of a worldwide decline in glass eels, particularly for the European and Japanese species.

“I was traumatised by it for years,” Dr Egan says. “It bit me several times.”
“Ear bones can tell us so much information about the environment a fish experiences on a daily basis. Each day they add a layer of calcium carbonate which is almost like keeping a diar y of their lives.
Next April, NIWA scientists will undertake a project that will complement Dr Egan’s work. In this new project, migrating female eels will be tagged and their location communicated to satellites to help pinpoint their spawning grounds in the western Pacific Ocean. N E W

Warming seas confirmed The seas in the New Zealand region are significantly warmer than 30 years ago and all indications are the warming trend will continue, a NIWA scientist says. Oceanographer Dr Phil Sutton says the strongest warming has occurred off the Wairarapa Coast, and the weakest along the northeast coast between North and East Capes. Increased warmth isn’t only at
“Since 1981 we are talking of warming of about 0.1 to 0.3°C per decade,” Dr Sutton said. While that may not sound like a lot, “a slightly stronger warming of about 0.4°C per decade off the east coast of Tasmania has resulted in significant changes to ecosystems.”

“We would expect to see this continue. The 30-year time series is long enough to see long-term changes and there is no reason to think this will turn around.”
NIWA’s Sea Surface Temperature Update is reported fortnightly to provide measurements of sea surface temperature and anomalies (differences from average) measurements for New Zealand coastal and Tasman Sea waters.
SSTs are well above average in the Tasman Sea with anomalies of +2.0˚C to 4.0˚C, and also above average in New Zealand coastal waters with anomalies of +1.0 to 3.0˚C.
A sea surface temperature anomaly is defined as the difference between the long-term (1981-2010) average sea surface temperature and current sea surface temperature for a given time of year.

Here’s seven favourite Wakatobi sites to showcase the amazing diversity here on offer for divers.
House Reef

At the outer edge, crevices and caverns riddle some steep slopes and sheer walls which are covered with hard and soft corals, sea fans and sponges. Regular visitors here include turtles and sizable schools of jacks and barracuda. The current on the House Reef ranges from mild to strong, which creates excellent opportunities for drift dives.

The Zoo
J
ust a quick boat ride from the resort is one of the fishiest places in central Indonesia. Not far offshore, a patch reef within a sand-bottom
bay is home to a wealth of intriguing marine creatures and plants. A casual look among the corals will show frogfish, ghost pipefish and leaf scorpionfish, hiding, though easy to spot. Closer scrutiny may reveal smaller prize sights, such as the hairy squat lobster and pygmy seahorses, and surveillance of the sandy bottom will yield bizarre burrowers such as the stargazer, and the alien-like mantis shrimp.

Between the drop-off and the beach lies a vast ecosystem of turtle grass shallows and isolated coral heads which creates a rich environment for the most odd and beautiful creatures; just some of them are frogfish, stonefish, octopus, moray eels, blue-spotted stingrays, ghost pipefish, jawfish, shrimp and goby pairs.

he Wakatobi House Reef is reputed to be the world's best shore dive. Divers and snorkelers access it right from the beach or the resort's jetty since the reef’s crest lies less than 80 metres offshore and rises to just two metres depth at low tide.

Zoo is a favourite place for night dives. At dusk a lucky diver might get to see the colourful mandarinfish emerging from staghorn coral and rubble. As the light fades further a new range of nocturnal animals such as hunting cuttlefish, bobtail squid, brilliant flatworms and many species of lionfish, including the elusive twinpsot lionfish, scour the reef.
Nocturnal critters such as the Bobtail squid can be spotted at dusk

he wide pinnacle known as Roma rises to within two metres of the surface. But the real story of this geological feature is what grows on and swims around the underwater plateau. The fringing ring of potato coral that encircles the crest has been likened to the Colosseum in Rome, hence the name of the site.
These formations are adorned with multi-colored crinoids and anemones with attendant clownfish. One slope is covered in a huge grove of Pavona coral providing shelter for small reef fish; the other is a drop off fringed with table corals, soft corals, and fans. Large barrel sponges point the way to Roma’s signature coral growth - a unique turbinaria coral formation more than six metres across

he crest of this prominent seamount is decorated with broad, mushroom-like growths of table coral. Their tops balance on slender supporting columns, and interspersed among them are groves of staghorn coral, patches of leather coral and wispy formations of lettuce coral. In contrast, the sides of the pinnacle are covered in colourful sprays of sponges and gorgonians.
Blade
Blade Blade is perhaps the most unique dive site in the region, and the furthest away from those regularly visited by the resort’s day boats. This distinctive formation consists of an elongated seamount rising from a deep ridge again to within two metres of the surface. In profile the entire formation resembles the serrated teeth of the edge of a giant knife. The elongated ridge-shaped formation is actually quite narrow allowing divers to view both sides of its seemingly vertical face simultaneously from the surface above. This majestic ridgeline is covered in colourful arrays of giant sponges and sea fans growing upwards of three metres across. Red whip corals grow thick here, offering fantastic photo opportunities. Multi-hued crinoids are often seen perched on the tips of gorgonians, extending their tentacles to catch passing food morsels. Mild currents allow you to drift from peak to peak, evoking a sensation of weightless flight. Blade is certainly an experience not soon forgotten.

ere a wide range of depths and mix of underwater environments all occur in close proximity. Coral formations rising almost to the surface surround a sandy bay decorated with coral heads and sea grass. But venturing seaward and the bay transitions from a slope to a wall with steep overhangs sheltering reclusive marine life and shade groves of black coral. Within the bay a large school of resident batfish mill about, hunting for morsels in the sand, or waiting their turn at cleaning stations. Cuttlefish frequent the area for mating and nesting. Razorfish and rockmover wrasse go about building their burrows while colourful nudibranchs inch their way through the sea grass and coral.

any of the shallow reefs around Wakatobi Resort start just a couple of metres below the surface then transition down to steep walls. One of the most popular of these precipices is the great wall of Cornucopia which combines a dramatic vertical profile with an above-average critter count. Nearer the surface, dense clusters of mid-sized sea fans dominate then, as the reef goes vertical, the face is adorned with the multi-hued coatings of soft corals. At even greater depths, larger and more solitary gorgonians mix with sponges and black coral groves while numerous undercuts perforate the wall, providing dark recesses for cometfish, juvenile grouper and a range of macro life.
This is a prime area to discover one of the most celebrated of sea slugs, the solar powered nudibranch. This large invertebrate adds variety to its diet of leather corals by cultivating colonies of zoocanthellae algae in its elongated tentacles.
A signature resident of these grottoes is the Randal’s shrimp goby. Unlike other shrimp gobies, which almost exclusively inhabit open sandy or silty bottoms, the Randal’s prefer the overhead environments indenting Cornucopia’s wall.

The Pelagian experience

At Wakatobi guests can board the dive yacht Pelagian for week-long cruises to take in a greater area of the Wakatobi Regency. The Pelagian carries just 10 guests attended by a crew of 12 delivering the highest levels of personal attention, from attentive cabin and dining service to diving preparation and in-water support. Each day the onboard chef creates meals worthy of a Michelin-starred restaurant - fresh local flavours in a menu also featuring international favourites. Pelagian's weekly itineraries take in a broad swathe of the Wakatobi archipelago – such as the fish-laden pinnacles near Hoga, and the big reefs of Karang Kaledupa and Karang Kapota where divers will find everything from coral-rich shallows to sheer drop-offs. For many divers a highlight of each cruise is the days spent in Pasar Wajo Bay where some of Indonesia's best muck diving is to be found, along with a signature experience at Magic Pier to observe the mating rituals of mandarinfish.

Wakatobi's commitment
to conservation
W
akatobi Resort is committed to a variety of proactive programs for protecting the environment while at the same time providing tangible benefits to the local community. The Wakatobi Collaborative Reef Conservation Program was established at the time of the resort's founding. This involved agreeing with the local people to designate a six kilometre section of reef as a marine sanctuary. Direct payments were made to villages in the area and their fishermen in exchange for honouring this no-fishing zone. The program has since expanded to include 17 local communities around the resort, and the sanctuary now encompasses over 20km of some of the finest reefs in the world. Since the establishment of the reserve, destructive forms of fishing have been eliminated, dive sites are protected by permanent moorings, fish populations have increased, and corals have returned to near-pristine status.

akatobi's fleet of spacious dive boats each make three daily trips to more than 40 sites within the Wakatobi private marine reserve. Each of these 21-metre custom-built launches is fitted with generous bench seating, bathrooms and storage areas under a full-length roof. To ensure each guest is given an appropriate level of attention, both in and out of the water, the resort typically maintains a ratio of one dive guide to four to six divers. There is also dedicated service for snorkelers who enjoy numerous shallow reefs accessible from the dive boats as well as full briefings and snorkel guides.

Breakthrough in research on freshwater mussels Freshwater mussels, ka-kahi which were once a valuable food source for many Ma- ori and play a crucial role in filtering waterways, have been in decline for years, but a recent breakthrough will help their restoration. Ka-kahi are often found tucked under banks, in shady pools and partly submerged in shady, soft-bottomed streams.

DS51
Researchers clockwise from bottom: Dr Sue Clearwater, Nicole Hanrahan and Michele Melchior measuring freshwater mussels. But Michele Melchior, a University of Waikato doctoral student, has discovered that one of the species, which can live to be over 50 years old, uses a different reproductive strateg y. It releases its lar vae in enticing packages called conglutinates to lure passing fish.
DS160 & 161
The lures are between 5 and 9 mm long, look like a small f latworm, and carr y on their back about 200 tiny lar vae, each about the size of a grain of sand. Fish attracted to these lures tr y to eat them, giving the lar vae a chance to attach to their gills. Once on the fish the lar vae can then transform into juveniles and catch their all-important “ride” to new habitat. “Long-term we might be able to use mussel rafts to improve treated storm water quality because they can degrade bacteria,” said NIWA freshwater scientist Dr Sue Clearwater. “Mussels might help make water more swimmable.”

Wrecks & reefs...
...Gizo to Munda Story and images by Dave Abbott Part 2: Diving
the Solomon’s
After three days of wreck-diving around Guadacanal it was time to fly out of Honiara on to Gizo for some mixed wreck and reef diving.
Internal flights in the Solomon’s are either on a Dash 8 or an 18 seat Twin Otter, real workhorses capable of short take-offs and landings, and ideal for island hopping! Small islands present their own problems when it comes to building airstrips, and Gizo’s novel way of solving this was by joining two small islands together and levelling them to make what is still a short runaway. Consequently
Gizo must be one of the few airports in the world with no parking lot because there are no roads here and no vehicles. Just a jetty.
Gizo and Ghizo
We were greeted at the tiny terminal by Danny Kennedy, owner of Dive Gizo, who ferried us over to the dive shop on the main island of Ghizo (same name different spelling) then across to another small island (Mbabanga) to spend
the night at the iconic ‘Fat Boys’ resort with its laidback restaurant built out over the water on stilts, great food and quirky but comfortable bungalows. With its amazing views over the lagoon, this is a great place to stay! The diving out of Gizo proved to be a nice blend of wreck and reef diving; we did five great dives with Danny, getting a good overview of what is on offer.

Our first dive was on the wreck of the Toa Maru, a nearly intact 140m long Japanese transport ship. The stern lies at 37m, the bow at 7m, making it a great dive profile.
Being intact it is easy to penetrate and take a look around inside, and there are still many WWII relics to see, from old Saki bottles and ammunition to a small Japanese tank.

small village brought us to Lola island, where, after lunch and an afternoon nap at Zipolo Habu resort, we were picked up by Dive Munda in one of their dive boats and taken across to Munda.

Antarctic’s Ross Sea to be further explored Twenty one scientists supported by 19 crew members departed on NIWA’s research vessel Tangaroa recently to study Antarctica’s ocean, atmosphere and ecosystem processes. Their focus will be on establishing monitoring programmes for the newly created Ross Sea Marine Protected Area (MPA). Scientists from China, Italy and France are also on board. At more than 1.55 million km2 in size, the Ross Sea MPA is the world’s largest and only a year old. Its zones range from fully protected to special research zones as well as areas left open to fishing. Voyage leader Dr Richard O’Driscoll says the main aim of the trip is to provide baseline information about the MPA so scientists can start to evaluate its effectiveness.
RV Tangaroa “During the voyage we will be making a range of obser vations from the atmosphere and water column. We will also undertake some biological sampling of small fish and fish living close to the seabed that are potentially impacted by the toothfish fisher y,” Dr O’Driscoll says.
“We are going to places we have never gone before and putting cameras down onto areas of the seabed where no one has looked before. It really feels like a voyage of discover y. The Ross Sea still has large areas which are unknown,” Dr O’Driscoll says.

Giant triplefin ~Blennodon dorsale
By Paul Caiger
New Zealand is a world hotspot for triplefins with 27 species and counting. The giant triplefin, as its name suggests, is at the larger end of the triplefin scale, only the Topknot is larger in New Zealand. The head of this stocky triplefin is its most identifying feature - small eyes on a bulbous head covered in warty protuberances, and large obvious teeth. In fact, so unique are the teeth that the genus Blennodon is named for them (meaning “blenny-like teeth”). Generally coloured mottled hues of grey and light brown through to olive-green help camouflage them in their surroundings. As males mature they become darker and more colourful, including red marks on the fins. Though this is one of the largest triplefins in the world, it is rarely encountered, due to its existence in extreme habitats. They mostly inhabit intertidal and shallow subtidal areas along the highly exposed west coasts of both main islands of New Zealand, such as in mussel beds, boulder areas and rock pools. Interestingly, as widespread around New Zealand as this species is, it is not found north of the Bay of Plenty on the east coast,
owing perhaps to the lack of turbulent intertidal habitats in this more sheltered region. Living in such an extreme environment in proximity to the near constant pounding of waves, and extreme changes in salinity and temperature with each tide, has likely resulted in the diet of the giant triplefin becoming highly specialized. All but two of New Zealand’s triplefins are generalist carnivores, eating pretty much whatever they can catch and fit into their mouth. But the giant triplefin is a specialist carnivore,
feeding exclusively on the small black intertidal mussel, Xenostrobus pulex. (The other specialist is the planktivorous oblique-swimming triplefin). Their large curved teeth are adapted to pulling bivalves off the rocks, with the mussels providing a bountiful resource with little competition for them. An evolutionary success story, the giant triplefin has exploited a unique niche to become the dominant species in areas of high turbulence in the intertidal and shallow subtidal.

INCIDENTINSIGHTS WITH THE DIVERS ALERT NETWORK (DANAP] By DAN Asia-Pacific
Six recompressions needed, on a liveaboard! By DAN's Marty McCafferty The diver: A 60-year old male
in good general health with no significant medical history.
The Diver’s experience:
Advanced Nitrox Certified.
The trip: Liveaboard diving
holiday to Coron, Philippines.
The dives: Multiple air dives
over three consecutive days with safety stops completed on each dive.
The dive profiles: ay 1: D • Max depth - 15m; Total Dive Time (TDT) - 40 minutes Day 2: • Dive 1 - max depth 10m; TDT 30 minutes; Surface Interval (SI) - 3 hours. • Dive 2 - max depth 20m; TDT- 25 minutes, SI - 3 hours. • Dive 3 - max depth 25m; TDT- 30 minutes. Day 3: • Dive 1 - max depth 27m; TDT 35 minutes; SI - 5 hours. • Dive 2 - max depth 24m; TDT 40 minutes.
ONSET OF SYMPTOMS Upon exiting the water the diver took a warm shower and within 10 minutes immediately noted progressive numbness and weakness of both lower extremities, which commenced on the lower left leg and progressed up towards the left abdomen and chest, with gradual pain and increasing difficulty walking unassisted.
54 Dive New Zealand | Dive Pacific
There was gradual progression of abdominal fullness with bloating of the stomach and pain when urinating. Oxygen was immediately provided on the boat by non-rebreather mask and was continued throughout the journey to Coron. The diver was also given oral analgesics to help with the pain, though they provided little relief. When the call was made to the DAN Diving Emergency Hotline, the liveaboard was on its way to Coron. However, due to the severity of the diver’s condition, DAN wanted the diver to receive a higher level of care and procedures were put in place to transport the diver via air ambulance to the decompression chamber at Quezon City in Manila.
TREATMENT When the diver arrived at the chamber on a stretcher he was conscious and coherent with stable vital signs. His key complaints were weakness and numbness of both lower extremities, abdominal fullness and discomfort, moderate lumbar pains and, due to difficulty urinating, the diver had a catheter.
With the symptoms persisting, the diver underwent a further three shorter decompressions (US Navy Table 5 Treatments at 2h 16 minutes each, to a depth of 18m, followed by a Table 9 treatment also at 2h 16 minutes, but to a reduced depth of approx. 14m) to deal with the residual symptoms. At the end of all treatments, the diver’s catheter was removed. He had improved balance, and was better able to walk unassisted. He was advised not to fly for an additional 72 hours and was required to undergo a diving medical examination prior to returning to diving. Unfortunately some symptoms returned during the flight home so the diver was sent to an emergency department shortly after arrival into Australia where he required further treatment and investigations.
RECOVERY The diver continued to improve slowly upon returning home. He was tested for a hole in his heart (a PFO), and the test proved positive. The diver elected to have the PFO closed. The procedure took place nearly nine months following the Decompression Illness incident.
Due to the severity of the symptoms the diver received six recompression treatments over six days.
Four months after the procedure the diver was given clearance to dive once again on the proviso he followed the guidelines below:
After each of the first two treatments (US Navy Table 6, 4h 45 minutes each, to a depth of 18m), the diver advised that the pain in his lower back was bearable and the numbness was reducing. He was able to stand independently for two minutes and walk a little, but remained wobbly, weak and uncomfortable.
• Conservative dive limits • Maximum depth 30m • No more than two dives per day • Minimum surface intervals two hours but the longer the better • Nitrox to be used where possible (on air settings) • Slow ascent and safety stops on all dives.
COSTS • Evacuation by air ambulance: USD$11,800 • Treatment (chamber and hospital): USD$10,650 All costs were fully covered by DAN under the member’s coverage option.
ANALYSIS This member was lucky that the liveaboard he was diving from had plenty of oxygen and that the crew understood that he needed oxygen to manage his condition (from their own personal experience!) while the boat was travelling to Coron. This likely contributed to his eventual recovery. The call to DAN was made shortly after the onset of symptoms and this enabled DAN’s assistance team to organise the evacuation to Manila and advise the chamber team so they would be ready to receive the diver.

All divers should remember that DCI can occur on what some would consider to be relatively innocent dive profiles. Even though these profiles were well within the limits of this diver’s computer, he became seriously ill. Further steps should be taken, particularly when in remote areas, to reduce the risk of DCI, by using such as a conservative setting on your dive computer and following the guidelines above that were suggested to this member. Through testing it was found that this member had a hole in his heart (PFO). We are finding that PFO’s are not uncommon. Approximately one in every four people have one. In this case the hole allowed bubbles to cross the heart bypassing the filtering provided by the lungs and resulted in serious symptoms. Having a PFO does not mean the end of a diving career. It does mean that the diver needs to have a serious discussion with a Divie Physician to determine what options are available and how to best manage the increased risk of DCI. In this case the decision was made to have the hole repaired and to change the way he dives to reduce bubble loading in the body. www.danap.org Need more information?

DIVEMEDICINE
Diving and Hyperbaric Medicine Journal: A valuable diving knowledge resource by Professor Simon Mitchell, University of Auckland
I
have found that divers who become passionate about our sport are “sponges” for reliable technical knowledge. The origin of such knowledge is science; a process that I will describe in more detail below. Unfortunately, the world of science can be a little impenetrable to non-scientists. Although we live in the so-called “information age” where the internet provides an accessible source of technical information, it can be difficult to evaluate the reliability and credibility of on-line information. Indeed, some material, presented authoritatively with the utmost conviction on internet discussion forums, can nevertheless be outright wrong. Scientists often avoid such forums because of the risk of being dragged into arguments with non-experts in a milieu where everyone’s opinions tend to be treated equally regardless of qualification and training. The true mouthpiece of science is the scientific literature. Collectively, the scientific literature is comprised of peer reviewed scientific journals that are typically published by academic societies with an interest in a particular field. These journals will publish scientific studies, typically without charge to the authors, so long as the study is of interest to the journal’s readership and successfully passes through a rigorous peer review process (see below). Unfortunately, there has recently been a proliferation of so-called “predatory journals” published by commercial entities whose focus is on profit; potentially at the expense of scientific accuracy. These journals purport to be peer reviewed, but there may be significant doubt about the quality of this process, and they charge the authors large sums of money to
56 Dive New Zealand | Dive Pacific
arrange funding (very challenging in diving research), and then undertake the study.
publish studies. You can see the obvious problem, but that is a conversation for another day. For a single study, the process of good science is often lengthy and expensive. The scientist authors will develop a hypothesis they want to test. Let’s say, to take a diving example, they
Once all the subjects had completed the protocol, the authors would compare post-dive bubbles in the two groups, and come to a conclusion about the veracity of their hypothesis. They would then prepare a manuscript for submission to a scientific journal. These manuscripts are typically short and to the point. Even a complex study is usually described in 3000 – 4000 words (about 3x the length of this article). They would choose a journal and submit the manuscript for peer review. The journal editor will read the article, decide whether it is of relevance to the journal’s readership and if so, send it to several experts (“peers”) who were not involved in the study who will review it. The peer reviewers will document any concerns about the study and
…there has recently been a proliferation of so-called “predatory journals” published by commercial entities whose focus is on profit; potentially at the expense of scientific accuracy… believe decompression procedure A is better than decompression procedure B. The related hypothesis might be something like “for the same depth and bottom time, decompression procedure A will result in less detectable venous bubbles than procedure B”. They will then design a protocol to test the hypothesis. In this case, it would likely be a study in which two groups of human subjects undertake a dive with the same depth and bottom time, but one group uses decompression procedure A and one group uses B. At standardized times after the dive the divers would be examined for venous bubbles using ultrasound. The authors would get ethics committee permission to proceed,
return their reviews to the journal editor who will in turn communicate those reviews to the authors. At this point the study may be accepted or rejected outright, but more typically the editor will want the authors to modify the manuscript to answer some of the reviewers’ criticisms before accepting the study for publication. There may be several rounds of review required before a study gets to this point. By such a process we generally get to the truth. There have been many examples of poor science being published (particularly in predatory journals) or even outright fraud where data are effectively made up. But
over time, science tends to be self-correcting; that is, repeat or related studies will identify aberrant results and correct conclusions will eventually be drawn. Publication of scientific studies in journals has traditionally taken the form of printed papers in subscriber-only publications that end up in science libraries out of the view of many potential readers. But, and this is the main good-news point of this article, this is changing and scientific publication is steadily transitioning to electronic format, with papers becoming increasingly available on publicly accessible resources. This has recently become true of a very valuable resource for divers. Diving medicine is a niche specialty and has only two journals dedicated to the subject in their entirety: Diving and Hyperbaric Medicine (DHM) published jointly by the South Pacific Underwater Medicine Society (SPUMS) and the European Underwater and Baromedical Society; and Undersea and Hyperbaric Medicine (UHM) published by the Undersea and Hyperbaric Medical Society in the USA. Part of the reason for writing an article of this nature at this time is that I have just taken over as the editor of DHM and I wanted to alert Dive New Zealand readers to its potential interest for those interested in advanced knowledge. DHM is now an exclusively electronic publication. It is published every 3 months and contains about eight scientific articles per issue. The full issues (from 2012 to March 2017) to can be downloaded by anyone from the SPUMS website: http://www. spums.org.au/content/full-issues ( https://tinyurl.com/y9rgz8yz ) SPUMS members can download full issues right up to the present. In addition, individual articles from March 2017 onwards are available through
an on-line repository called Pubmed Central. The most recent year of articles are embargoed (and are available only to members through the website above). But anyone can access articles that are over a year old. As examples, here are links to a few that have become available recently.

The contrast of beauty versus impact! By Dave Moran, Editor at Large
I
t is always interesting at this time of the year to see how many Kiwis escaped New Zealand’s winter, as shown by a couple of our winners. It also good to see Kiwi divers enjoying a winters dive. Goat Island Marine Reserve never disappoints. Over the years we have received many winning images taken in this jewel in New Zealand waters. Three of the images have Drama/Impact while Alex Stammers’ image is just simply stunningly beautiful.Once again, we see the amazing results that can be achieved by a high-end compact cam-era. View the “wow” image of a Humpback whale calf taken
by Simone Matucci with a Sony RX100 MkIV compact camera. The judges again encourage the use of post photographic programs such as Adobe Light-room to improve the final presentation of an image. Give it a go --- it can be fun seeing what you can do! The judges and the team at Dive New Zealand/Dive Pacific magazines look forward to receiving your personal masterpieces.

Judges’ comments:
58 58 Dive DiveNew NewZealand Zealand| |Dive DivePacific Pacific
This image is undoubtedly a winner. Having the diver’s eyes, framed a third in and a third down the image is great composition!
The fact that the diver is also ringed by red gorgonians enhances the image even more. The diver’s video lights also tend to pull the viewers’ eyes in towards the diver. Great soft, subtle lighting from the strobes too!
Advanced Highly Commended:
Congratulations Simone Matucci, New Zealand.
One of the joys of diving off the island of Ha’apai, Tonga is the possibility of encountering a Humpback whale or its calf. An amazing experience! Simone receives a Gift Voucher for NZ$75.
Judges’ comments: A magical image of a very close encounter. With its left fin hanging down, this helps to fill the space below the whale's body. If its right fin was out, that would have added extra magic. We are guessing that the whale has tucked in its right fin so that it would avoid the possibility of striking the diver. These whales are very perceptive of their surroundings! Using Lightroom to lift the bottom shadow detail and reduce slightly the top highlights would have improved image slightly.

Judges’ comments:
Central composition doesn’t often have appeal, but it seems to work well in this image. It is always interesting to have something big swimming towards you! The dehaze and highlight sliders in Adobe Lightroom could have given this image a lot more impact.

‘Dolphin Pod 1’’; Goat Island Marine Reserve, New Zealand: Canon 7D MkII, Tokina 10-17mm, Ikelite housing – f/3.5, 1/250, ISO1000
Novice Category Winner: Congratulations, Dan Westerkamp, New Zealand. Dan was enjoying a late afternoon freediving in the Marine Reserve at Goat island when he was surrounded by 10-15 bottlenose dolphins. Dan managed to snap off a few shots while the sun was setting!
Judges’ comments: A nicely composed image. The photo is visually interesting because you can see the dolphin’s tail movement at different steps of their swim cycle. A little tweaking in Adobe Lighroom could have improved the underwater visibility using the dehaze slider.
Dan receives a Gift Voucher for NZ$75.

DIGITALIMAGING Hans Weichselbaum www.digital-image.co.nz
Full-frame? Or crop-size sensor? In the previous issue we looked at mirrorless full-frame cameras and compared them with the more familiar DSLR cameras. With Nikon and Canon recently joining Sony’s Alpha series in the mirrorless world, full-frame cameras are in the headlines again. The question is, do you really need a full-frame camera? And how do they compare to crop-sensor cameras? That’s the topic of this article.
T
he full-frame format refers to a 36x24 mm sized sensor which was adapted from the common 135 film format and introduced by Kodak in 1934. Just to make things clear from the outset: the more light the sensor can capture, the better the image quality. If you want the very best, you need to go full-frame. But why stop there? There are medium format cameras out there with even larger sensors. When assessing image quality, we are looking at a moving target. We can only compare current cameras because each new generation of sensor comes with significant improvements.
Each pixel can be thought of as a little bucket collecting photons of light. All else being equal, the larger the bucket, the higher the sensitivity and the lower the ‘noise’. Larger numbers of pixels also bring an improved dynamic range and higher colour depth. I said all else being equal because, as we just noted, sensor technology keeps improving, their light detecting cells as well as the surrounding circuitry, amplifiers and processors. So we can only compare current camera models. A certain number of MPixels is needed to resolve image detail
…Canon’s first full-frame camera, the EOS-1Ds from 2002 sported 11 MPixels and an ISO range of 100-1250. Back then this was a serious professional camera, but any of today’s cell phone cameras would put it to shame… Case in point, consider Canon’s first full-frame camera, the EOS-1Ds from 2002. It sported 11 MPixels and an ISO range of 100-1250. Back then this was a serious professional camera, but any of today’s cell phone cameras would put it to shame.
Collecting Photons and MPixels Apart from sensor size another important factor affecting image quality is the number of pixels on a given sensor. A full-frame and a crop-sensor can both accommodate the same number of pixels, say 25 MPixels.

Image sensor which are larger than the actual sensor diameters. These units go back to the TV camera tubes from the 1950s. The sensor size is about two thirds the size of the imaging circle. Image 1 gives you an example of a 2/3” sensor. Note that most compact cameras have an aspect ratio of 4:3, whereas the full-frame sensor has a 3:2 ratio.
and for printing to a given print size. In this article I will consider only the sensor dimensions, not the pixel count. That will be the topic of another article, but keep in mind that the overall number of pixels and the pixel density do affect image quality.
Sensor sizes The Table below shows some examples. Sensor size is often referred to with a “type” designation using imperial fractions such as 2/3” (inch) or 1/1.7”,
Image 1 - Example of a 2/3” Sensor with its Imaging Circle
Below I list only some of the most common sensor sizes and you can look up the dimensions for your particular camera and see where it fits into the Table. Image 2 gives you a graphical comparison.
Table 1 - Some common sensor sizes
Pros and cons of a crop-sensor camera The main advantage of cameras with smaller sensors is their reduced bulk and weight. The lenses only need to project a smaller image circle and can also be designed a lot smaller. Needless to say, the reduced bulk of a camera plus lenses also eases the stress on your wallet. The wildlife photographer will appreciate the longer reach of common tele lenses. For example, a 200mm lens on a Four Thirds camera (which still has a reasonably large sensor) will turn into a 400mm lens. However, you also need to multiply the maximum aperture by the crop factor as well. Your f/4 lens will slow down to f/8.
…Each pixel can be thought of as a little bucket collecting photons of light. All else being equal, the larger the bucket, the higher the sensitivity and the lower the ‘noise’…
Image 2 - Comparing some common sensor sizes
This brings us to the question of whether to use full-frame lenses on crop-sensor cameras. Many people think a lens costing many times more must also give them the better results, but it often turns out that the cheap kit lens designed for the smaller sensor will give you sharper images! You can check out the image quality to expect from any lens/camera combination at https://www.dxomark.com/Lenses/Ratings
Depth of field Depth of field (DOF) is a hotly debated topic. Most photographers, including professionals, will tell you to get a full-frame camera because its larger sensor can create a shallower DOF. This is not strictly true since only focal length, distance to the object, and aperture affect DOF, not the size of the sensor. In practice, with a larger sensor and the same lens, you need to move closer to your subject to maintain the same frame, thereby getting a shallower DOF.
When comparing cameras and lenses the ‘crop factor’ is important. Some people call this the “focal length conversion factor” but it is a crop factor because the part of the image circle outside the sensor gets cropped. Image 2 shows how a smaller sensor basically crops the image from a full-frame sensor. It is easy to calculate by dividing 43.3 by the sensor diameter. For example, a 1/1.7” sensor with a diagonal of 9.4 mm will give you a 43.3/9.3 = 4.7 crop factor. This sensor would turn a 50 mm lens into a 230 mm tele lens.
Cell phone cameras with their teeny-weeny sensor go to some elaborate software tricks to get their background blurred. So, there is some truth that larger sensors make it easier to isolate your subject. A full-frame camera will always capture more light than its smaller siblings. The question is, will you notice the difference? Thanks to the high quality of today’s sensors it is quite likely you will only notice an improvement in image quality under very low light situations!

Chapter 3:
Back to the Basics
A Practical Guide for Beginners by Alexey Zaytsev Second edition translated from the Russian exclusively for Dive magazine. (All photo's by Alexey Zaytsev)
Alexey Zaytsev is well known amongst Russia’s dive and underwater photography community, and has undertaken professional photographic assignments in many places around the world, including many visits to Egypt, Sudan, Bali and elsewhere. To illustrate the book, and also his own credentials, Alexey is making available a selection of his fine photographic work. Alexey lives in Auckland, New Zealand.
Aperture, shutter speed and all… Photography, regardless of on land or underwater, teems with terminology and quite often one thing can have several different names. Professional photographers may skillfully juggle these terms often replacing them with colloquialisms. So it is not surprising that a beginner can easily get intimidated and start panicking… In reality, it is not as intimidating and complicated as it seems. So together let’s go back to the basics and clear the air so you are never again confused or feel uncomfortable in a company of super professionals.
Can we skip this part? We shouldn’t and mustn’t! It is just as important as the physics of gas for a diver. Without the basics of photography, you won’t be able to fully master underwater photography. Take my word for it. Plus, it is interesting and not complicated at all.
"Mola mola" Mempang, Candidasa, Indian Ocean, Bali island, Indonesia. Nikon D700 lens 15 mm F2.8 (f8; 1/160; ISO1250) Ikelite housing, strobe Ikelite DS160 64 Dive New Zealand | Dive Pacific
"Hangar for Hydrojet Saucer DS-2" Precontinet II, Sha’ab Rumi Reef, Red Sea, Sudan. Nikon D700 lens 15 mm F2.8 (f10; 1/200; ISO400) Ikelite housing, two strobe Ikelite DS160
Let’s start with the camera set up‌ Good news for beginners: in principle, all cameras are the same. Any single one of them, regardless of whether it is digital or analog, has: 1) a lens with a diaphragm inside (f) 2) a shutter (s) 3) l ight sensitive material or a microchip (film in traditional cameras and a sensor in digital ones) (ISO) 4) a viewfinder
frame of modern cameras can be less than that of a 35 mm camera, hence a different focal length. In this case, optics manufacturers indicate another value for the focal length in lens specifications which is equivalent to the focal length of the 35 mm format. It can be easily calculated: the actual focal length of a lens is multiplied by a crop factor (the value by which the camera sensor is smaller than the 35 mm frame of an analogue camera). You will be able to read more about sensor sizes later in section 3 – Sensors.
5) LCD screen.
Lens speed
Look at the drawing of a photo camera below. It's not that bad is it? Let's talk about important components of the camera in greater detail.
Lens speed is an ability of a lens to transmit light. By the fastest lens photographers mean their largest maximum open aperture. Both the lens speed and its focal length are always shown next to the lens' name, for example, Sigma 15mm F2.8
in the technical specifications of the lens, and if you look at the lens itself, you will see this value at the focus scale. It is measured from the focal plane or the sensor plane. The following sign on a camera body indicates where this plane is located in digital cameras:
Working distance Novice photographers often confuse the minimal focusing distance with the working distance. The working distance is a distance between the front of the lens and a subject if located at the minimum focusing distance.
Angle of coverage
1 Lens and aperture
The angle of coverage of a lens is measured along the frame's diagonal! All lenses form an image in a shape of a circle. The diagonal of the frame is the diameter of that circle. In other words, the frame (the sensor) of the camera is inscribed in this circle.
Any photographic lens consists of a group of elements and equipped with a diaphragm. What's important to know its focal length, lens speed, angle of view, minimal focusing distance and working distance.
In essence, the diaphragm is an opaque screen with an opening and closing hole (aperture) in the middle. The size of this hole or aperture can be changed automatically by the camera or by a photographer as he or she desires.
Focal length Focal length (F) is the distance in millimeters between the optical center of the lens and the surface of the sensor. The shorter the focal length, the wider the lens' angle of coverage. The longer the focal length, the smaller the angle. For years photographers were shooting with analog cameras using so-called 35 mm film. The focal length of such lenses has somewhat become a 'standard' easily understood by any experienced photographer. The size of a
Diaphragm
Minimal focusing distance Since you must get as close to your subject underwater as possible, this feature of the lens becomes of utmost importance in defining its suitability for underwater photography. Choose lenses with the shortest focusing distance! You will find information about them
Probably, to intimidate or confuse novice photographers even more, a letter 'f' is used in literature to indicate the diaphragm. Moreover, it is often referred to as 'aperture'. That is the precisely the reason why 'A' is used to indicate the aperture priority shooting mode on the camera. Not many owners of digital cameras know about the existence of the aperture, or its purpose. How wrong is that! The knob that controls the aperture on an underwater housing is as important for
www.dive-pacific.com 65
an underwater photographer as a gear stick for a driver. You need to know where it is and be able to change it automatically! So what is it and what do we do with it?
(or dark) is dark, and grey is grey.
3. If your lens doesn't have the aperture scale (ring), rotate the dial on your camera body that changes aperture settings. Note: some cameras have one dial that controls both shutter speed and aperture. To switch between shutter speed and aperture, you would have to press a special button. Please, see the user manual for your camera!
The fish and the gate Let's use an analogy with fish and a trap with a gate to help us understand how the aperture works. The aperture could be the gate leading to the trap, and light could be the fish. If you open the gate (aperture) wide then a large number of fish (light) can enter the trap within one unit of time. If you close the gate (aperture) leaving a small crack, then very few fish (light) will be captured in the trap (on a camera sensor). In other words, a diaphragm is a screen that allows the photographer to control the amount of light entering the camera at his or her own discretion. What do we need it for? In order to be able to take a correctly exposed image, of course! When we translate from the photographic language, this simply means taking a good photograph, where white (or light) is light, black
4. Look at the camera's monitor. You should be able to see an aperture value next to the letter 'f', for example, f 5.6. 5. Rotate the dial in either direction and you will see the aperture value change. For example, f 5.6 will change to f 5, then to f 4.5, f 3.5, f 3.2, f 2.8. If you rotate the dial in the opposite direction, the values will change to f 6.3, f 7.1, f 8, f 9, f 11, f 13, f 14, f 16, f 18, f 20, f 22.
Aperture values Stop reading this book for a moment, pick up your camera and run the following experiment: 1. Turn on your camera.

2. Set the shooting mode to 'M'.
6. The smallest aperture value shown on the lens indicates the largest aperture, meaning that the largest amount of light will hit the sensor. For example, the aperture value of f 2.8 has become

position closing the aperture to its maximum value.
7. The highest aperture value, for example f22, physically corresponds to the smallest aperture, through which very little light can pass.
12. If your lens has an aperture scale, move the ring with the scale and look through the lens. You should be able to see how the diameter of the opening formed by the blades of the diaphragm changes.
8. Take the lens off your camera, but only if it's a DSLR or a compact camera with interchangeable lenses. Don't try to tear off an unchangeable lens from your point-and-shoot! 9. Look at the light through the rear of the lens. You will see a diaphragm mechanism consisting of several blades – it will be closed to the maximum possible value, for example f 22. 10. You will also see a lever on the rear side of the lens. Carefully not to pull it too hard, move the lever all the way to the side until it stops. You should be able to see the blades of the diaphragm open up to the maximum value, for example f 2.8. 11. Let go of the lever and the spring inside the lens will bring the blades back to their original
Consecutive full-stop F-numbers If you own lenses that can be used with analogue cameras, you will find an aperture ring on most of them. This ring is used to set aperture. You will also notice that the ring has several values – f 2.8; f 4; f 5.6; f 8; f 11; f 16; f 22 and f 32. Shifting from one value to a higher one, we are reducing the amount of light that can pass through the lens. And visa versa. The amount of light will be reduced by a fraction of two with every change of values. Remember this magic number! We will see it again. This chain of consecutive values is called a full-stop F-number scale. Not every lens has a full range of f-stop values. In some cases,
the widest aperture (f-stop as it is referred to by professional photographers) can be fractional. For example, f 3.5, as in a popular among underwater photographers Tokina 10-17mm.
Fractional (partial) values Fractional (partial) f-stop values are invisible increments that are located between markings indicated on the aperture scale. These can be set on the camera and will be shown as fractions on the display. What are they for? They allow you to choose the exact amount of light that will hit the sensor thus ensuring that your images are properly exposed. In some models of digital point-andshoots, such as Ricoh that divers know as Sea&Sea DG-1, the f-stop sequence looks like this: f 2.5; f 2.9; d 3.2; f 3.6; f 4.1; f 4.6; f 5.1; f 5.7; f 6.5; f 7.2; f 8.1; f 9.1 – all values in the sequence are fractional! It is not confusing but rather helping the camera take better pictures…

Three great dive pioneers pass on Lynton Diggle is a name many of you will know, especially if you have been diving since the 1960’s, made his name as a cameraman / producer of documentaries. He joined the New Zealand National Film Unit in October 1957 and was involved in many expeditions to Antarctica. He filmed the recovery of bunker oil off the wreck of the SS President Coolidge Espiritu Santo, Vanuatu as well as the oil removal from the Russian cruise liner Mikhail Lermontov in the Marlborough Sounds in New Zealand along with footage pulling huge containers off ships stuck on reefs. Lynton became involved with the late Kelly Tarlton filming salvage operation on the SS Tasmania off the Mahia coast at the time when Kelly was recovering much of the Rothchild’s jewels. He also
Allan Power was one of the
great identities of scuba diving. Allan was very highly regarded among his peers; divers travelled the world to meet him and share his passion for diving and love of the marine world especially around the wreck of the SS President Coolidge in Vanuatu. His timeless book The Great Barrier Reef published in 1977 became a treasured classic. After moving to Espiritu Santo to undertake a salvage operation Allan established Allan Power Dive Tours there, a company held in
Bob Halstead was a towering
figure in the international dive community and a regular contributor to Dive Pacific magazine. His photography and writing, smart device apps, and the promotion of diving in general, Papua New Guinea in particular, were great and varied. As a celebrated underwater photographer, his work featured on countless magazine covers and won numerous awards. He published eight books on diving and marine life, as well as hundreds of magazine articles (sometimes controversial).

filmed Kelly in association with Oscar winner film producer David Lean when they discovered and recovered one of Captain Cook’s anchors which Cook lost in 1773 in Tahiti. His wife Edith was his soul mate and fellow researcher as shipwreck research became their main interest. Edith had a column in Dive New Zealand: Shipwreck Lady. They partnered up with Keith Gordon to publish the 8th Edition of NZ Shipwreck recording 530 wrecks in its 576 pages! He was also a member of Auckland’s Reefcombers Spearfishing club and with a love of caving and spearfishing.

He will be greatly missed.
high regard worldwide. In 2011 Allan was inducted into the International Scuba Diving Hall of Fame in the Cayman Islands. This prestigious award recognised his contribution to the diving industry with specific mention to his work and achievements on the SS President Coolidge.

His best-known book, Coral Sea Reef Guide, was later released as a marine life identification app: Bob Halstead’s Coral Sea Fish Guide App. Probably the thing Bob is most known for though, was his coining the term “muck diving” and introducing countless divers to a form of diving that had previously been left to scientists. As an instructor and dive guide in Papua New Guinea, Bob was second to none. His spirit and sense of humour were notoriously infectious. He was inducted into the Scuba Diving Hall of Fame
