Abstract
The Pechora Sea is a Barents Sea part located in the southeast. The natural conditions of the Pechora Sea are very different from the Barents Sea water area. There are various types of water masses and many dynamic processes. The purpose of the study is to assess the components of the water, heat and salt balances of the Pechora Sea. Based on the monthly average data of the CMEMS GLORYS12V1 and ERA5 reanalyses for the period 1993–2018, the water, heat and salt transport at the boundaries of the Pechora Sea (in longitude 50 E on the west, latitude 71 N on the north and in the Kara Strait) and the characteristics of the sea surface-atmosphere interaction are calculated. The average long-term resulting water transport on the Pechora Sea boundaries coming from the west (0.36 Sv) and from the north (0.04 Sv), leave the Pechora Sea through the Kara Gates (0.40 Sv). It is shown that in the region there is heat excess coming due to advection, which is compensated by sea-atmosphere interaction. All transports during the study period have a significant positive trend, which characterizes the growth of the transit of North Atlantic water through the Pechora Sea.
