This article belongs to the Special Issue “Physical and Biological Properties of Waters in the Region of the Antarctic Peninsula and Adjacent Basins of the South Atlantic,”: a Special Issue that is dedicated to recent research in the Atlantic sector of the Southern Ocean and Antarctica Peninsula region. The papers in this issue are focused on the field and theoretical research of the physical properties and ecology of this key region in the Southern Ocean. The main objects of the study were the properties of seawater, currents, the ecosystem, and biological communities in the South Atlantic, the Powell Basin of the northwestern Weddell Sea, the Bransfield Strait, and the Antarctic Sound. The Antarctic marine ecosystem is unique was terms of its biodiversity and high productivity of basic trophic levels of the ecosystem. This ecosystem was efficiently used by organisms such as seabirds, seals, and whales that fed on Antarctic krill.
The Antarctic Circumpolar Current System (ACC) and oceanic circulation at higher latitudes near the Antarctic continent are the oceanographic basis for the functionality of the Antarctic marine ecosystem. The processes in this region of the World Ocean have been intensely studied in recent decades but still remain not completely understood because of an insufficient number of expeditions to this region. The processes in Antarctica require more and more investigation by scientists. In recent decades, the Southern Ocean has experienced significant changes associated with global climate trends.
These issues of the Water MDPI journal have been composed on the basis of analyzing the results of multi-disciplinary studies based on the physics and biology of the Atlantic sector of the Antarctic during two cruises in January-February 2020 and in January-February 2022 on the R/V Akademik Mstislav Keldysh (cruises 79 and 87) [1,2].
This issue presents the results of multidisciplinary studies in Antarctica. The issue includes articles on marine physics, marine chemistry, and marine biology, which jointly compose a comprehensive multidisciplinary approach to a modern view of the processes that govern the mean state of the ocean and its variability. Research has been performed in the region of the Antarctic Circumpolar Current, Weddell Gyre, Weddell Sea, and Bransfield Strait. The most important areas of study were the Bransfield Strait between the Antarctic Peninsula [3], the South Shetland Islands, and the Powell Basin east of the northern tip of the Antarctic Peninsula [2].
Research has also been conducted in the region of the South Orkney Islands and Orkney Passage east of the Powell Basin. The Orkney Passage is the main pathway for Antarctic Bottom Water flow from the Weddell Sea [4]. On the route of the ship to the Antarctic continent, the propagation of Antarctic Bottom Water has been studied in the Vema Channel [5]. The upwelling on the Patagonian shelf and Malvinas Current became a topic of multidisciplinary research during the expedition. We also studied the processes across an eddy dipole in the interaction zone between Subtropical and Subantarctic waters in the Southwest Atlantic [6].
