Абстракт
Abiotic characteristics of the waters in the Bransfield Strait were studied in a section from the South Shetland Islands to the Antarctic Peninsula. The Bransfield Current was recorded northeastward flowing along the archipelago with a speed of 20-47 cm/s. It is marked by the water temperature and salinity in the core (2.7 degrees C and 34.18%). The depth of the lower boundary of the euphotic layer varies from 40 m near the South Shetland Islands to 80 m on the shelf of the Antarctic Peninsula. The oxygen content and parameters of the carbonate system indicate the predominance of production over destructive processes in the surface layer of the central part of the Strait during the period under study. A countercurrent from the Weddell Sea was recorded on the shelf of the Antarctic Peninsula, which is distinguished by the oxygen saturation (90%) and silica content (74 mu M). Four water masses were identified in the region under studied: Antarctic Surface Water, Circumpolar Deep Water, modified water of the north-western Weddell Sea shelf, and Bottom Bransfield Water.
