“…Chlorophyll-a was the primary index for trophic status index classification and was the most accurate of the three variables used in predicting algal biomass according to Boyer et al (2009) andNincevic-Gladan et al (2015). In view of this assertion, trophic status in the study area was oligotrophic as revealed by the mean TSI of 25.68 µg/L for chlorophylla which falls within the upper boundary of classical oligotrophy.…”

“…Chlorophyll-a is a surrogate measure of phytoplankton abundance in the water column and its levels are increased by nutrients (USEPA, 2012). It is also an important pigment in phytoplankton that can provide indications on the trophic status, water clarity and phytoplankton biomass, Boyer et al (2009) andNincevic-Gladan et al (2015). Therefore, the trophic state generally refers to aspects of aquatic systems associated with the growth of algae, decreasing water transparency and low oxygen levels in the lower water column that can harm fish and other aquatic life (USEPA, 2012).…”

“…LUSI index (Land Uses Simplified Index) was developed by [3] and is the recommended pressure index in the context of the Mediterranean Geographical Intercalibration Group. It has been widely applied in different areas of the Mediterranean Sea [4]- [7]. This index is based on the different land uses of areas limiting the studied coastal water, as well as on the morphology of the coastline (concave or convex).…”

The European Water Framework Directive aims to achieve a good status of all inland and coastal waters in the European Union by evaluating the status and the anthropogenic pressures to natural water bodies. As such, several techniques have been developed to evaluate the anthropogenic pressure to coastal areas. The most widespread methods are indexes, although some authors have also used the application of models. Using indexes has many advantages, such as the simplicity or the fast application. The anthropogenic pressure is generally assessed through the application of an index which is calculated based on parameters such as population density, urbanization, industry, agriculture, fisheries and maritime transport. However, the dispersion of contaminants along the coast is a factor that is generally overlooked by such indexes. Natural coastal waters have been widely assessed in Member States. On the contrary, heavily modified coastal waters, which are generally located close to the biggest urban areas, have been left aside in the evaluation process. To demonstrate that minimizing pollution in heavily modified coastal waters is a must, we evaluated several nutrient concentrations in natural coastal waters of the Jucar River Basin District, located in the Western Mediterranean Sea (Spain). We calculated the correlation between nutrient concentrations and several anthropogenic pressures, including the presence of adjacent water bodies considered as heavily modified by human activity under the Water Framework Directive. Then, a forward stepwise linear regression was applied to identify the activities most affecting nutrient concentrations. It was found that the presence of a neighbouring water body classified as heavily modified was the main driver of nutrient concentration differences among natural water bodies. These results suggest that the evaluation of anthropogenic pressures to coastal waters should also consider the dispersion of pollutants from adjacent heavily modified coastal waters.

“…Most eutrophication assessment methods recognize that the immediate biological response is increased primary production reflected as increased chlorophyll a (Chl-a) and/or macroalgal abundance (BRICKER et al, 2007;OSPAR, 2008;NIXON, 2009;NINČEVIĆ-GLADAN et al, 2015).…”

Ova studija predlaže metodologiju za nadgledanje koncentracija klorofila-a i eutrofičnog stanja u malim zalivima ili u blizini obale. Ova vrsta nadgledanja je zanimljiva jer uobičajena satelitska metodologija, bazirana na MODIS satelitu, nije funkcionalna u ovim oblastima zbog nedovoljne prostorne rezolucije senzora. U ovom radu je predstavljen pristup procjeni koncentracija klorofila-a baziran na Landsat 8 satelitskim snimcima i mjerenjima koncentracije obavljenim na određenim lokacijama na dan prelijetanja satelita. Dodatno, dva klasifikatora stanja (dnevni i godišnji) eutrofikacije, koji koriste određene koncentracije, su također prikazani. Preciznost predloženih metoda je procijenjena koristeći „leave-one-out“ unakrsnu validaciju, te rezultati pokazuju da je preciznost unutar teoretskih limita metoda baziranih na Ladsat 8 satelitu. Rezultati klasifikatora upoređeni su sa mjerenjima na terenu i pokazuju da je dnevni klasifikator u mogućnosti da klasificira oblast od interesa sa manje of 2% pogreški.
