- Аннотация: Hydrographic observations, carried out in March-May, 2019 during “Transarktika-2019” expedition onboard R/V“Akademik Tryoshnikov” allowed studying mechanisms of Atlantic Water (AW) transformation in the Barents Sea.Although this research topic is rather traditional for oceanographic studies, there are still a number of questions, whichrequire clarification. Among these is a deeper understanding of the AW transformation in specific regions in cold season,when the coverage by observations is scarce. In this study we performed temperature and salinity (TS) analysis ofconductivity — temperature — depth (CTD) data, collected in the north-eastern “corner” of the Barents Sea — this isthe area with difficult access in winter due to high concentration of pack ice. The results allowed identification of areasalong the pathways of AW branches, where various types of open sea convection and cascading acted as dominantprocesses of AW properties change. We distinguish several driving mechanisms controlling modification of the watersof Atlantic origin. An advantage of winter measurements is that the active stage of AW transformation mechanismsis explicitly observed at the consecutive CTD sections.
