Letter from the Associate Editor By: Jenny Johnson, Associate Editor
A
loha!
My name is Jenny Johnson and I am so excited to be the new Associate Editor of Seawords! Growing up in Washington, I was always near the ocean or some body of water. This created a love for the ocean and an awareness of how important ocean conservation is. Animals have also consumed a huge part of my heart and life, as I received my Vet Assistant certificate before moving to O‘ahu. My love for animals and the ocean brought me not only to UH Mānoa, but also to MOP. I started out at UH Mānoa as an animal science major, then marine biology and finally found my true niche as a communications major. At the time of switching to communications, I didn’t want to lose touch with the ocean which is why I came to Hawai‘i. Fortunately, MOP has allowed me to remain in marine related courses, find marine related internships and opportunities and continue my passion towards ocean and marine animal conservation. One of my other passions is having fun! When I’m not in class or doing homework you can find me in the water or on a hike. I live everyday thankful that I am able to live on this beautiful island! I am extremely thankful for my new position as Associate Editor, training under Editor, Kayla White. With this position, I have the opportunity to spread awareness of what is happening in our oceans, on the Hawaiian islands and around the globe with the help of our incredibly talented writers! n

MOP BARBEQUE By: Jenny Johnson, Associate Editor
G
ray skies and misty rain greeted the MOP students on the morning of the MOP Back to School BBQ. Sleepy but excited students stumbled into the MOP office one after the other around nine a.m.. Alas, all of the students made it to the office and it was time to pile into the van. Nervously, I awaited my new duty as van driver but Alexa, MOP Student Coordinator, assured me it wasn’t a tough job. We buckled our seat belts, turned up the tunes and we were headed to Bellows Beach for a day of delicious food and many laughs. As I gripped the van’s steering wheel tight through the Pali highway, students gazed out of their windows, taking in the sweeping views of the green, lush mountains and the perfectly turquoise ocean. The drive went quickly and before we knew it, we had made it to Bellows Beach! Everyone hopped out of the van and felt the big gusts of wind hit their skin. Promise of a sunny day peaked through the clouds overhead. Jeff had already arrived and had the chairs, tables and BBQ set up. We quickly dropped our belongings onto the chairs and helped set up the food, as most of us were very eager to start eating.
chilly to get in the water just yet. A few students began playing volleyball while myself, and MOP Students Taylor Peterson, Keli Hall, and Richard Chen, played an intense game of Bocce Ball. Taylor Peterson and I faced off against Keli Hall and Richard Chen. After the first few throws, it was apparent that previous softball player, Taylor, was going to be carrying our team. To my dismay, I have a pretty weak throw. Although Taylor was carrying our team, the score remained relatively equal throughout the game. The final throw, made by Richard Chen, won the game for himself and Keli Hall, with a final score of 7-5. When asked how they won, Richard Chen said, “Just being better than the other team” while Keli Hall noted that winning requires skill, she explained “With skill and agility and determination.” The first set of activities left some students, including me, wanting to go back for seconds although it left other students such as Jacey Reinken and Kayla White needing a nap in their cozy and comfortable hammock. After filling a second plate, I watched some of the students play an entertaining game of boys vs. girls volleyball with an innovative makeshift net which was setup with three big sticks and a rope. Who knew we had so many volleyball stars in MOP? Next to me, also enjoying the game, sat MOP Student, Amanda Tieman, and her adorable little half chihuahua half corgi rescue pup, Lola. Lola loved running around the beach, digging in the sand and lounging on her mom’s towel. She created just as much entertainment for me as the volleyball game did. After the girls won the volleyball game, and the sun had come out to warm us up, it was time to hit the waves. Students ran into the crashing waves and dove straight in. Keli Hall caught some waves on the surfboard while other students boogie boarded and body surfed. After everyone had gotten their wave fix, it was time to start packing up and call it a day.
“The burgers by Jeff Kuwabara, MOP Coordinator, were better than Teddy’s burgers” Kayla White, Editor. Kayla was definitely right. Students chowed down on burgers made with Jeff ’s superb barbecuing skills. Patiently, I waited for my veggie burger, but that didn’t stop me from digging into the many delicious sides that everyone brought. Savory and sweet food lined the table. Potato and mac salad, pita chips and hummus, barbecued veggies, hot dogs, chicken, fruit, popcorn, cookies and cheesecake made everyone’s mouths water. The biggest hit was MOP Student, Taylor Peterson’s, incredibly delicious and addicting fruit dip though. Students filled their plates and enjoyed their food either under the trees or down at the beach. For any MOP students who have not been to the Back to School BBQ yet, do not miss it again! There is nothing Stomachs were full, students were awake and it was time more fun than being surrounded by great people and to start some fun activities. MOP Students, Jacey Regood food for a day at the beach! n inken, Drew Lara and Kayla White instantly ran to the water and jumped in. The rest of us were still a bit too MOP members enjoying Bellows beach. Photo by: John Johnson.

Whale you be my Valentine?

DIVE SAFETY
Finding the Perfect Dive Buddy By: Tyler Phelps, UHH MOP Alumnus

t’s February and you know what that means, love arrows from Cupid crowding the sky! For those of us celebrating “National Singles Awareness Day” on February 14, now might be the perfect time to think about the qualities that make someone your perfect match, as your dive buddy.

A Place For Everyone By: Chloé Peterkin, HCC Student
Here, the sky is ever changing. The tints and hues change with every tick and tock. The shapes of “unicorns” and “bunnies” fill the sky. The air is replete with the same salt that seasons the water. The crystal blue waves bring forth a new story with every cool warm crash. The shrieks from the children that race their dogs into the water become muffled by the waves that wash over them. The memories of those before and after stretch out from shore to horizon. The palaces are built across the land with the same golden grain felt between toes. Where one comes to get away, and another comes to join with others, the beach becomes a place for everyone. Chloe’s poem was chosen from a collection of poems submitted to us by Eric Paul Shaffer, an HCC English Professor, and written by his English 201: Creative Writing class.

critter of the month By: Alina Abramovich, UHH MOP Student
Zebra Blenny
(Istiblennius zebra) - pao`o Distribution: Endemic to the Hawaiian Islands Size: Up to 7.5 inches Diet: Mostly algae and organic marine detritus Coloration: Normally blue-black or grey but can change at will to a more striped pattern for camouflage Habitat: Benthic, reef-fishes, seemingly preferring basaltic shorelines and reef locations Depth: Up to 3m in depth IUCN Red List Status: Least Concern, Stable
U
ndulating like an eel, the zebra blenny (Istiblennius zebra) is most often spotted in surf zones and basaltic tidepools close to shore. This reef fish is highly adaptable and has been found in varying surf zone depths, pH levels, tidepool temperatures, salinity and oxygen content. The blennies are also marked by their amazing agility and their ability to leap from tidepool to tidepool in order to gain access to food, avoid predation and find potential mates. Physically, the zebra blenny is also distinguishable by a flap-like, nuchal crest found between its eyes (which is larger in the males). Blennies tend to congregate into tight, abundant groups (up to dozens have been observed sharing the same pool space) and seek out hiding spots amid their fellows as a form of protection. The preference for tidepools also stems out of the abundance of large crevices and boulders wherein the blennies will also hide. Zebra blenny adults have a blue dot pattern under their eyes, and blennies of all ages have a tendency to become mottled when they are taken by surprise, or when feeding in shallow water.
Feeding mainly on organic marine detritus and algae that accumulates on the basaltic rocks of their tidepools, the blennies rarely venture into deeper water preferring the tidal buffett that their exposed homes provide. The aforementioned eel-like undulations of their bodies allow the blennies to wriggle almost out of the water onto rocks where they look out for potential predators. If they do spot an unsavory creature (sometimes from up to 50 ft. away), the blennies escape by leaping, crawling and skipping out of sight. These acrobatic fish can even jump up to two feet above the waterâ&#x20AC;&#x2122;s surface in order to try and remain safe. Zebra blennies are thought to reproduce mainly in the spring and early summer, with the males building nests in rock crevices and fertilizing the eggs that the female hatches within the nests. Once formed, the larvae drift out to sea and find their way back to the tidepools when they are about a half an inch long. n Zebra Blenny (Istiblennius zebra). Photo by: Ken-ichi Ueda, Flickr.

February Surf Report By: Alina Abramovich, UHH MOP Student
T
he month of January ushered in the winter swells we had all been waiting for - with several days of high surf advisories and, arguably, the first wake-up call for Waimea Bay this year. In other exciting New Year developments, this reporter has transferred to UH Hilo and so these reports shall now cover both the Big Island swell forecasts, as well as Oahu’s swell forecasts. Luckily this year has so far been more than kind to the coasts of both these islands, and swell predictions show that the La Niña NPAC (North Pacific) storm trends look favorable in this upcoming month. Surfline’s report states that although traditionally February marks the “other side” of the winter swell peaks, the climatological models are all indicating that the first couple of weeks will hold a higher potential for a more powerful NW swell, with variable winds. The second half of the month looks like it may be easing into smaller swells and a more typical E/ENE trade wind pattern. For Oahu’s North Shore, this forecast looks promising, as most spots up in the country prefer this combination of winds and smaller (but still rippable) waves. Big wave surfers are perhaps the only ones who will feel let down by this prediction, seeing that after this month we are already edging into the beginnings of SPAC (Southern Pacific) swell territory. However, the climatological data underplayed some of the bigger, better swells that hit early in the New Year, so perhaps February will hold some surprise bombing days as well. As for Big Island, we can only hope that some of those easing swells (or freak bigger swells) will bypass Maui and hit our northern exposed shores with as much gusto as they did in January. Hilo side is predicted to pick up some of the more northeasterly exposed swells, as well as have a consistent supply of ridable wind swells during the next month. Overall, it seems that both islands will have rideable waves and that the winds will become a little more consistent and cleaner. Happy surfing! n

Shipwreck of the Month: Pacific Paradise By: Madelyn Rangel, UHM MOP Student
O
n October 10, 2017, in just six feet of water, the Pacific Paradise wrecked on a sandbar outside of Kaimana Beach Park in Waikīkī. The tuna fishing vessel ran aground just a few hundred yards offshore. Of the 20 people rescued from the wreck, 19 were foreign workers, later released to the United States Customs and Border Protection. The 79-foot craft caught fire after one of the first unsuccessful attempts to remove it. Concerns were voiced by the Waikīkī Aquarium, which pumps in ocean water from a location near the wreck for its monk seal exhibit. The aquarium demanded water quality tests to assure that no harm was done to its animals. Finally, on December 7, the Pacific Paradise was removed from the site and sunk at an EPAapproved site 13 miles south of O‘ahu. It was estimated that up to 1,500 gallons of fuel may have remained onboard.

The shipwreck raises questions around the fishing fleet laws in Hawai‘i. Loopholes in current legislation enable fishing boats to employ workers from impoverished nations in Southeast Asia and the Pacific for extremely low wages, such as those who were onboard the Pacific Paradise. Foreign workers are not allowed to leave the fishing boats, so were essentially imprisoned on the 80 foot vessel. n

Weddell Seal
Marine Mammal of the Month:
Weddell Seal
M
Species: Weddell Seal Scientific Name: Leptonychotes weddellii Range: Antarctic coasts and surrounding islands Diet: Fish, squid, krill Size: 10-12 feet long
any seal species can be found on the Antarctic coasts, from the cute crabeater seal (Lobodon carcinophaga), to the massive elephant seal (Mirounga leonina), and the voracious leopard seal (Hydrurga leptonyx). Among them all, the Weddell seal, yet another Antarctic pinniped, may not seem too impressive at first glance. Sure, itâ&#x20AC;&#x2122;s as adorable and appealing as any other seal, but what exactly sets it apart? A fairly large seal, reaching maximum lengths of twelve feet long (but more often remaining
14|â&#x20AC;&#x192;Seawords
closer to eight feet), the Weddell seal looks unassuming compared to its other polar compatriots. Known for its abundance and placidity, this creature is the best-studied pinniped in Antarctica, thanks to the fact that it has high tolerance for people around it. Multiple videos can be found on the internet of people (perhaps not fully legally) touching these creatures with apparently little care. Howe ve r, these tolerant seals show one unique behavior that places them among the most remarkable of creatures on the Antarctic continent. When the A Weddell seal (Leptonychotes weddellii) sleeping. Photo by: Ronald Woan, Flickr. winter storms come and

All other seals – in fact, all other mammals – will migrate northward to escape the freezing onslaught of the harsh polar winter, while the Weddell seal will mostly remain in the same spot all year long. In fact, most of these docile creatures will hardly travel more than a few miles from their birthplace their entire lives, and will only feel prompted to travel any sort of significant distance if they need to find food. Only one other warmblooded creature will remain this far south all year long, the Weddell seal’s only winter companion, the emperor penguin (Aptenodytes forsteri). Weddell seals have evolved some helpful traits to handle the rough winters, the most notable being their jaws. They are among a group known as the lobodontine seals, which are known for highly specialized, interlocking teeth that allow the creatures to filter small prey items, such as krill, from the water. They share this grouping with the leopard, crabeater, and Ross (Ommatphoca rossii) seals. However, Weddell seals’ canines are even more specialized than that of their brethren, and they use their jaws to constantly maintain breathing holes in the sea ice so that they do not freeze over in cold tem-
peratures. Weddells also keep an eye out for weak cracks in the ice to open new breathing holes, should the need arise. They are known for their excellent underwater vision, which not only helps in locating prey, but spotting these breathing holes, or weaknesses in the ice, from the dark aquatic world underneath. Sadly, constant maintenance of breathing holes can wear down their teeth and make it hard for them to catch prey, causing many seals to become no older than eighteen years of age, while other seals who don’t cause excessive wear to their teeth can live to 30 years of age. Besides this shortened lifespan, however, Weddell seals are fairly well-off for marine mammals. Their large size and preferred hunting locations of under the ice make them at a lower risk of predation from orcas (Orcinus orca) and leopard seals once they pass adolescence. While they were hunted by poachers in the past, their habits of living on Antarctic coasts (as opposed to ice floes further out to sea) made it hard for would-be hunters to reach them, and their abundance today shows this. They don’t have to undergo the hassle of yearly migrations like so many Antarctic seals do. Maybe that’s why they seem so docile all the time. n FEBRUARY 2018 |15

Sea Turtles Freezing in Florida A harsh winter has taken Florida by surprise. On January 3rd, snow was recorded in Tallahassee, a phenomenon not witnessed since 1990. While the frigid temperatures astonished Florida residents, the climate proved fatal for local green sea turtles. The National Park Service, with the help of other local organizations, rescued over 1,000 sea turtles stuck in a state described by scientists as “cold stunned.” The rescued turtles were taken to a laboratory to be tagged before moving to a rehabilitation facility that will home them until temperatures rise.

Green sea turtles aren’t the only ones not able to fair the sudden weather changes. Manatees exposed to water temperatures lower than 68 degrees F may experience hypothermia, “cold-stress disease” or develop lesions, known as “Florida frostbite.”
In 2010, hundreds of sea turtles and manatees were killed by a similar cold stint.

Actions for the Ocean
GENERATION
BLUE

O
ur oceans produce half of the world’s oxygen supply while absorbing carbon and regulating our global climate. Due to overfishing and the introduction of contaminants into the ocean, human activity has become a severe threat to marine biodiversity. Many of these pollutants, including fertilizers and pesticides, runoff into coastal waters causing eutrophication and resulting in the oxidation of ocean waters. This process creates uninhabitable areas for marine life known as dead zones that can become the size of New Jersey. Each year, 8 million tons of plastic enter the ocean. Knowing this information, it is our duty to protect the ocean’s biodiversity. Below are some steps toward a healthier ocean environment. n
Buy Locally to Reduce Ship Pollution
1: 18| Seawords
Even though most pollutants are land-based, pollution caused by ships can be just as harmful. Ships are well known for accidental oil spills, introducing invasive species, and for noise pollution. In areas prone to ship traffic, populations of whales and dolphins have declined due to the effects of noise pollution. Sound waves from ships can carry for miles in the ocean, disrupting cetacean migration patterns, communication, search for food and can also lead to beaching. By purchasing items locally, we can help reduce the negative effects that ship pollution has on marine life.
THE OCEAN SPANS OVER 70 PERCENT OF OUR WORLD. It is responsible for regulating temperature, food production, sustaining numerous species, and is a source for inspiration for many people.The ocean gives us so much and it is time for us to return the favor and take actions to make the ocean ecosystem healthy again. Almost every action that we take affects the ocean in some way. Our everyday choices can be tailored to support a healthy ocean. Here are some examples of green acts that will keep the ocean blue.
Support Sustainable Farming Practices

By purchasing organic produce and consuming less meat we can help reduce the number of contaminants entering the ocean. Chemicals used for conventional farming methods allows harmful runoff to enter the ocean causing dead zones and toxic chemicals accumulating in a marine food chain. Organic agricultural methods are less hazardous to marine life as they only depend on natural fertilizers to grow crops. In farms, animals are fed antibiotics and hormones that enter the ocean through agricultural waste, causing similar effects as conventional farming practices. Through the release of greenhouse gases, animal farming leads to increased ocean temperatures and ocean acidification. Consumers can help change the agricultural industry by increasing the demand for sustainable farming methods through purchasing less meat and more organic produce at the grocery store. Demand drives supply, so if there is less demand for these harmful things, eventually there will be less supply.
Volunteer & Educate Others
Volunteer for organizations that focus on educating the public about marine conservation or protecting endangered species. You can also educate your family and friends about how they can protect the ocean.

FLASHBACK: NOVEMBER 1986
T
his flashback dates all the way back to November 5, 1986, when a team of MOP students and MOP Coordinator, Annie Orcutt, from the Mānoa and Windward campuses, returned to Halepalaoa Landing at Lāna‘i, on the northeast side of O‘ahu, to conduct an underwater survey. Annie and the team decided to return to assess the underwater changes that had occurred due to the construction of a pier earlier that year.
By: Jennifer Johnson, Associate Editor challenge, but the weather was as well. The team had to prepare to battle the rough winter waves and the unpredictable weather. They made sure they were well-prepared with tents, sleeping bags, food and first-aid kits. Annie showed confidence in her team when she said, “It’ll be a bit rougher, but it’s nothing we can’t handle.” n
The pier and the changes made to reef, such as blasting for a new channel, were funded by a private cruise company that ran out of Kā‘anapali, Maui. This cruise company needed to make changes to the aquatic environment because the shallow depth of the water and the abundance of coral heads created challenges for boats going back and forth from Kā‘anapali to Halepalaoa. The MOP team ran into some difficulties while planning the return to Halepalaoa Landing. The team had set a date to return in August, but the completion of the pier was delayed. This caused many difficulties with planning because by the time the pier was completed, fall classes had already begun for the MOP students. Consequently, everyone’s schedules had changed and it was back to square one. Finally, the team was able to find a week that worked for everyone’s schedule, departing on November 4. Not only was scheduling a
