Features of plankton community in the Chukchi Sea in August-September, 2017
Zooplankton in the eastern Chukchi Sea is described on the data of summer observations in 2017. The northern part of the surveyed area was occupied by the cold water masses from the Arctic Ocean and Beaufort Sea. Large-sized zooplankton dominated here, including copepods Calanus glacialis, C. hyper...
