Abstract
The aim of the paper is to identify current trends in oceanographic conditions of the Barents Sea.
The material for the study was the data obtained during surveys in the Barents Sea by PINRO. As well as other available information on hydrometeorological conditions of the Barents Sea was used.
Methods of descriptive statistics as well as comparative, correlation and regression analyses were applied.
Results: An overview of meteorological (storm activity, air temperature) and oceanographic (sea water temperature and salinity, areas of water masses, ice coverage) conditions of the Barents Sea in 2016–2020 is presented. The period from 2016 to 2020 is characterized as warm, low-ice, fresh and with increased storm activity. Since the record warm year of 2016, there has been a declining trend in water and air temperatures as well as in the area occupied by warm Atlantic waters in the Barents Sea, while an increasing trend has been observed in the sea ice extent and areas of Arctic and cold bottom waters in the recent years. At the same time, for the investigated period, storm activity remained stably high, and salinity was still at a low level.
Practical significance: The obtained results of the analysis of the Barents Sea oceanographic conditions are useful for better understanding the processes occurring in the sea ecosystem and possible scenarios for their development, especially in the context of current global climate changes in this region, being of great importance for the fishing industry.
