Spatial and Temporal Variability of the Thermohaline Structure of Waters in the Antarctic Sound

Abstract

The sea straits of the Antarctic Peninsula region are characterized by intense currents, the presence of sea ice and large icebergs, strong tides, and many other factors that shape the thermohaline structure of the waters of this region and its temporal variability. The state of local ecological communities depends on the thermohaline properties of waters in the straits, which determines the relevance of this work. From this viewpoint, the Antarctic Sound, which connects the Bransfield Strait with the western Weddell Sea, is a very special object. Based on new field data, the thermohaline structure of this strait is described. For the first time, we have used unique data from autonomous sensors attached to local marine mammals, which made it possible to track water changes throughout the year. Transitional seasons are defined, as well as common limits of thermohaline characteristics of the waters in the strait. The spatial, seasonal, and interannual variability of the thermohaline structure of the waters in the strait was studied based on the data collected in the last 40 years.
