1. Introduction This report is written upon the request of the project “Satellite near Real Time Monitoring Network of the Eutrophication Risk for Marine Waters over the Greek Albanian cross border area” SAIMON for “External Expertise for “in situ” data collection and Sampling” in the Ionian Sea, Albania. The goal of this report is to make an assessment of the activities developed during the monitoring program implementation for the physic-chemical parameters of water quality. The report is focused on the monitoring program developed and implemented by all partners of the project and problems, gaps and difficulties analysed to give the clear situation of trophic status of Ionian Sea and implemented according to the WFD requirements. It is clear that the program validation based on satellite images cannot realized without the monitoring “in situ” where the minimum time period will be not less 2 times for the year referred to the wet and dry period. This is based on changes and relationships of the temperature, pH, chlorophyll-a regarding to the resolution of satellite images.
Photo 1. Transparency measurement by the Secci Disc When a new program is being started, or a lapsed program is being reinstated, it is useful to begin with a small-scale pilot project like a SAIMON project. This provides an opportunity for all involved partners to gain hands-on experience and to confirm whether components of the program can be implemented as planned. It may also provide an opportunity to assess the sampling network and provide indications of whether more (or possibly fewer) samples are needed in order to gain knowledge of the water quality at various points throughout a water body.

During the preliminary survey it is important to test assumptions about the mixing of monitoring points at the selected sampling sites and times. It might be appropriate, therefore, to consider variations in water quality at selected sampling sites throughout an annual cycle in order to confirm the number of samples required to produce representative data. In a sea it may be necessary to sample at different points to determine whether water quality can be estimated at a single point or whether the sea behaves as a number of separate water bodies with different water quality characteristics. It is also essential to investigate variation in water quality with depth and especially during stratification. Ionian Sea, at its littoral, is generally well-mixed at overturn (i.e. when stratification breaks down) and sampling from a single depth or the preparation of a composite sample from two depths may adequately represent the overall water quality. All these elements are taken into account when the monitoring program has been implemented during the project time life. At this report it is provided the assessment of the results taken during the sampling campaign and results of analyses in chemical laboratory, also, taken “in situ” by the multiparametric probes.
Photo 2. Multi parametric probe for pH, CE, O2 and T0C Data are collected during two field sampling campaigns respecting the guide of the sampling techniques and also the time storage and transport of the samples. The sampling campaign is carried out from the sampling team of EFB and JON Studios. 2. Selection of the sampling points Processes affecting sea water quality and their influence should be taken into account when sampling sites are selected. A sampling site is the general area of a water body from which samples are to be taken and is sometimes called a “macro location”.
5
The exact place at which the sample is taken is commonly referred to as a sampling station or, sometimes, a “microlocation�. Selection of sampling sites requires consideration of the monitoring objectives and some knowledge of the geography of the water-course system, as well as of the uses of the water and of any discharges of wastes into it. Sampling sites are marked on a map after a final decision on the precise location of a sampling station that are made by the project staff and EFB and JON Studios. The selected numbers of monitoring stations are selected to assess the magnitude and impact of the significant point source, diffuse source and hydro-morphological pressures. Based on the pressures present in the areas along the Ionian seaside, Albanian part has defined the monitoring stations for completing the aim of the project. These monitoring stations are defined based on ToR-s given by the Client, National Monitoring Programme

for washing waters and directly by this project taking in consideration the specific characteristics as the activities applied in selected points and “blank” points. 2.1. Vlora bay stations The South Coast Area is 244 km long (45% of the Albanian coast) and starts in the southern city of Vlora, continues in the Orikumi Bay and ends at the Greek-Albanian border, in Cape Stillos. From geographical point of view, Vlora bay is included at Adriatic watershed and partially in Ionian watershed, where discharges its waters through its hydrographic network of Vjosa River. Watershed of Vlora bay is bordered on north with watershed of Ionian Sea. The stations chosen for the monitoring programme applied in Albanian part are:
1Vlora bay 1st station – at coordinates X = 4372265, Y = 4479707. It is in the front of the Vlora bay, in western part, just to the shallow seawater. The territory in this area has a considerable settlements surface which is very adapted for urban wastes, sewage and industrial activities, etc. Also, in this side of the sea, fishery and livestock breeding are developed as an economic activity. These activities are in a non-problematic level in the area. 2Vlora bay 2nd station – it is in the same line with the first point. The difference between two points stays at the distance from the shoreline and the bathymetry of Ionian Sea. In both stations the tourism is developed and has its influence because the numerous bars and restaurants and sewage system which discharged in Ionian Sea.
2.2 Orikumi bay station It includes the zone to the south western part of Vlora city at Karaburuni Peninsula. Behind the sampling points there is Orikumi lagoon that is the smallest in Albania. It occupies a surface of about 100ha. It is connected with the Ionian Sea. To the south this lagoon is limited from alluviums of Dukati River and to the north by Ionian Sea waters. It is separated from Ionian Sea by a thin belt of clay depositions. It is shallow and discharges its waters by a pumping station in case of over raining. The selection of the stations is based on the main pollution resource in the lake and also on the main pressures coming into lake from point and diffuse sources of pollution.

3. Description of the sampling campaigns – First phase The plan for sampling campaign was discussed in Working Group meeting on March 2016, where all participants discussed for the water quality parameters of chemical, biological and microbiological assessment. All the parameters are recommended by WFD and will be used to assess the water status for its chemical and ecological quality. Also during this meeting the monitoring program implementation was discussed. According to the monitoring program the water samples are taken at all sampling stations described above at respective stations and locations, in one sampling campaign, which is belonged to one season, as it is recommended of WFD. The data about the sampling campaign put in monitoring field sheet where data from the location (coordination), weather conditions, water of sea visibility (transparency) and the parameters measured in the field were prescribed. According to the field sheet data the weather conditions during the field campaign were: 1- On March 2016 - good sunny weather and no wind, no wave During the first sampling campaign 17-20 March 2016 and 24-27 March the EFB consortium sampling team has completed their work in easily conditions accompanied quite sea, normal temperatures and no waves.

The field monitoring sheet will be attached in this report when the monitoring program will be completed with the second campaign, in June 2016.
4. Description of the sampling campaigns – Second phase On June 2016 - good sunny weather and no wind, no wave During the second sampling campaign 15-19 March 2016 and 20-22 June the EFB consortium sampling team has completed their work in easily conditions accompanied quite sea, normal temperatures and no waves. The field monitoring sheet is attached in this report because the monitoring program is completed with this last campaign.
5. Methods for sampling, transport and storage, analysis 5.1. Sampling techniques Collecting of samples was done by one motor-boats, the owner of one is the private subject. One day was spent for collection of samples in each station during the campaigns. Samples of water were taken by Ruthner bottle of 3 litres, which was providing by EFB consortium. Water samples were taken at two depths (surface and bottom of water column) in all the stations. All sampling procedures conducted according official standard methodology using field equipment. Samples for general chemical analysis were collected in containers of polyethylene bottles or glass bottle 1 litre. Samples for chlorophyll-a are collected in dark glass bottles of 1.5 litres after the measurements directly in the sea by the multi parametric probes. All samples are registered putting the code of the sampling site, parameters that will be analysed and the amount of the sample according to the procedure of the registration and also the field sheet data are filled in site during the sampling campaign. 5.2 Preservation/treatment of the samples According to the standard for preservation and treatment of samples EFB consortium has used the table below for the physio-chemical parameters of water quality: Table no. 1 Physio-chemical parameters of water quality Parameter Chloride Chlorophyll DO (Winkler) pH Inorganic

Bottles with samples were disposed in cooling boxes, at low temperature. The samples were transported to laboratory by car. The containers with samples were saved from any outside influences. The samples carefully transported to laboratory as soon as possible from the sampling day. When the samples came in laboratory, they disposed in refrigerators at 4 °C, waiting to analysis.
5.3 Methods of parameters/indicators measures All analyses for water quality parameters were done according to the agreed standard methods. Temperature of water, depth, transparency, pH, were measured in the field by thermometer, Secci disk, multi-parametric analytic equipment that was calibrated before in the laboratory. The samples of chlorophyll-a were filtered through the glass filter 0, 45 µm, as soon as they come in laboratory. All the other parameters were analysed in laboratory within determined time according to the specification methods of each parameter. The parameters of water quality are measured in laboratory of national Environmental Agency that use the standard methods like ISO, EN standards or methods taken from the American manual for water and waste water examination. Sampling of chlorophyll a was carried out in the following part of the southern Albanian coast. The device with which is used for sampling is called Hydrolab DS5. It measures the water quality parameters “in-situ”. At the same time with the measurement of chlorophyll a were measured water temperature and salinity, also. Selected points, for each station, where measurements were made were two bus; the first point near the shore and the second item 1 km from the coast. The level of chlorophyll a by sampling points is provided in the following table. The place's name with the number 1 is the nearshore sampling points and the number of sampling points 2 is 1km far from the coast.

5. INTERPRETATION OF THE RESULTS Based on the results of the first and second phase seems to be a clear differences between the chlorophyll-a content. These results are going together with temperature differences. So, for the higher temperatures we can distinguish higher values of chlorophyll-a. At the same time the content increasing in second phase is linear in comparison with the first phase with small differences in values. Based on these values, we can show that, at the same stations and respective points, are kept the same “anomalies� in values. The results show that near the coastline points and in specific points as Vlora bay, Qeparo, Saranda Bay and Stillo Cape, the chlorophyll a content is higher as other points. We can interpret these values as result of urban discharges in Vlora Bay, Qeparo, Saranda Bay and the industrial discharges in Stillo Cape where the fish industry is developed nearby.

Graph. 12 Transparency and its trend The highest concentration of chlorophyll-a is in surface because of the sun is stronger fall perpendicularly and more easily absorbed. With depth increasing it decreases absorbing ability which consequently decreases the concentration of chlorophyll-a. We can conclude until now that points with the highest level of chlorophyll â&#x20AC;&#x201C; a were observed in points of 30
1- Vlora 1 - g/l, Vlora 2 - 0.44 g/l, 2- Qeparo 1 and 2 by 0.43 g/l. 3- Other points are the level of chlorophyll from 0.1-021 g/l
Photo Saranda bay Referring to the level of chlorophyll publications in transitional waters, coastal and marine at the following website: http://www.eea.europa.eu/data-and-maps/indicators/chlorophyll-intransitional-coastal-and-2/assessment, we can see that the concentration of chlorophyll – a in the seawater can be classified monitored low and medium. Point’s lower concentrations of chlorophyll are Lukova 1 and 2 and Kakome 1 of 2. In the above graph are surrounded by the green colour. The rest included the average concentration of chlorophyll-a. Points where the average chlorophyll concentrations observed are settlements like the city of Vlora, Orikum of Himare, Dhërmi village of Qeparo. Discharges from these settlements are entitled to rights of wastewater in the city of Vlora and internal waters, which emit large quantities of nutrients.

The highest concentration of chlorophyll-a is in surface because of the sun is stronger fall perpendicularly and more easily absorbed. With depth increasing it decreases absorbing ability which consequently decreases the concentration of chlorophyll-a. We can conclude until now that points with the highest level of chlorophyll – a were observed in points of 12345-
Kakome 1by 1.6 g/l Qeparo 1 by 1.9 g/l. Saranda1 by 2.1 g/l Cape of Stillo by 2.5 g/l Other points are the level of chlorophyll from 0.9-1.5 g/l
Referring to the level of chlorophyll publications in transitional waters, coastal and marine at the following website: http://www.eea.europa.eu/data-and-maps/indicators/chlorophyll-intransitional-coastal-and-2/assessment, we can see that the concentration of chlorophyll – a in the seawater can be classified monitored low and medium. Point’s lower concentrations of chlorophyll are generally 1km far from the coastal line in all measured points where the value
33
0.9 shows the minimum value for all points. The rest included the average concentration of chlorophyll-a. We must note that in the second phase there has been a 500 m measurement, in comparison with the first phase where there have been only two measurements (1m and 1000 m). Points where the average chlorophyll concentrations observed are settlements like the city of Vlora, Orikum of Himare, DhĂŤrmi village of Qeparo. Discharges from these settlements are entitled to rights of wastewater in the city of Vlora and internal waters, which emit large quantities of nutrients.

6. CONCLUSIONS Based on both periods of measurement and especially in the second phase measurements, is clear that chlorophyll content is increased. The chlorophyll a increasing caused by the higher water temperature. Secondly the chlorophyll-a content depended from the station location. Near the coastal line the chlorophyll a content is higher in comparison with the station in the open sea because of the human and industrial activities discharged in the sea. In the table no. 16 are shown all the values for all the TSI indexes, explained above, in the methodology, explaining also the trophic indexes for each station. In all the measurement points along the Ionian coastline the trophic indexes tell us about an oligotrophic situation. The Chlorophyll-a content decreases toward the depth.

7. RECOMMENDATIONS This project has been a good collaboration between all experts for the collaboration between institutions involved in this process. This experience should be continued as a monitoring activity plan where the NEA should be leader and coordinator for all activities such establishing the monitoring program of seawater quality, especially for transboundary waters and they should make a good plan for human and tools resources (Instrumental infrastructure), ensuring the communication between partners on both sides of Ionian Sea and also different collaboration with governmental organization in national and international level. Making a good monitoring program means making selection of the stations, parameters, frequency, methods of sampling and analyzing, making assessment of received results and at the end making a good report for management of the seawater. All this process should be part of NEA objectives and work. The implementation of the new monitoring program where the Water Satellite Observation needs to identify the human capacities and to coordinate the work between different monitoring programs and organizations that are or not responsible for implementation of the environment monitoring issues (physic-chemical, biological, microbiological and other important parameters as are prescribed in WFD requirements). So, a combined database, provided by different institutions can help for a good monitoring system for the sea waters. The validation and calibration of the remote sensing data should be done through harmonized data provided by the first and second campaign undertaken in Ionian Sea. The satellite image it will be better in cell with the size 1:50/1:30 in order to profit the best resolution. Based on the cell size depended the distance between two points for sampling (density).
