Abstract

Field works on cruise 79 of the R/V Akademik Mstislav Keldysh aimed at investigating the ecosystems in the Atlantic sector of Antarctica were conducted from January 16 to March 1, 2020. Hydrophysical and biological studies were carried out in the Drake Passage and the Bransfield and Antarctic Sound straits. The regions of Russian fishery interest were covered. Data were collected that characterize the environmental state; plankton communities, including krill, ichthyoplankton, macronecton; bottom fauna; and spatiotemporal variations in the most important ecosystem components.
