We also observed seasonal blooms of diatoms\u00a0<em>Skeletonema, Chaetoceros, Rhizosolenia<\/em>\u00a0and <em>Thalassiosira.\u00a0<\/em>Diatoms are important for the marine ecosystems. However high nutrient concentration (particularly from human activities) in the water may lead to excessive proliferation of diatoms, inducing the hypoxic-anoxic conditions.
