Water quality of the Anabar River indicated by phytoplankton structure and hydrochemical characteristics

This is the first study of phytoplankton structure and physicochemical characteristics of the full length of the Anabar River-a large river in the Arctic basin. The study has revealed characteristics of phytoplankton assemblages and hydrochemistry of the reaches of the river. Water quality was found to decrease where mineral resources industry operates. The data on phytoplankton structure and physicochemical characteristics of the upper reaches of the Anabar River can serve as reference for monitoring the river status during commercial development of the area.
