Objects: Bellingshausen Sea, currents on the shelf of the Antarctic Peninsula. The goal of the project is to study the circulation and processes of water mass formation on the shelf of the Bellingshausen Sea, including as a factor of biological productivity under conditions of climate change in Antarctica. The report presents the results of combining the ocean circulation model around Antarctica and the Lagrangian method of tracking the trajectories of virtual particles in order to study the features of circulation and water mass formation in two important regions of the Bellingshausen Sea: the Bransfield Strait in the north and in the ice shelf area in the south of the sea. The study used the circulation data in the Weddell and Bellingshausen Seas from the detailed WAOM circulation model to analyze the trajectories of water masses using the Lagrangian Parcels model. At the same time, new kernels were developed for the Parcels model, one of which ensures the conservation of the number of particles in the flows around the irregularities of the bottom relief and the lower edge of the ice shelf, and the other is used to parameterize convection in the upper mixed layer. The obtained statistical characteristics of the particle movement, such as visitation frequencies and characteristic trajectories, allowed us to identify the structure of the flows between the Weddell Sea and the Bellingshausen Sea, as well as the structure of the flows in the northern and southern parts of the Bellingshausen Sea. It was found that the main source of particles transported from the Weddell Sea to the Bellingshausen Sea is the shelf zone adjacent to the Larsen Ice Shelf. In the southern part of the Bellingshausen Sea, water flows that have flowed out from under the ice shelves in the Bellingshausen Sea mix with the waters of the Antarctic Circumpolar Curr  Product Description popup.authors Brovchenko Roman V.
