Abstract

Extensive increase of phytoplankton is considered as a threatening factor in marine ecosystems by influencing food networks and biodiversity. Increase of minerals and nutrient due to human activities cause abnormal increase of this microorganism. As a result, phytoplankton biomass monitoring can be used as an effective method for identifying marine ecosystem from human activity pressure and eutrophication. In this study SEAWIFS and MODIS AQUA data were used for the study area. After preprocessing of CHLOROPHYLL-A and SST data and extracting time series algorithms of these data from 1998 to 2015, rate of the changes calculated by median trend. Result of this test showed that amount of CHLOROPHYLL-A concentration in the investigation surface water area from 1998 to 2015 have increasing trend (0.02 mg/m3) and also SST (Sea Surface Temperature) increased 0.11°C. Also, result showed good correlation between a concentration and MNEMIOPSIS LEIDYI (R2=0.65). In other words, amount of chlorophyll a Concentration in the alga bloom area is more than another area. In hence, one of the most important in chlorophyll a is algal blooms.
