Abstract
The results of statistical processing of the occurrence of krill individuals depending on some environmental factors, based on the actual data of hydrophysical measurements, at the studied stations in the Powell Basin of the Weddell Sea, the Bransfield Strait and Antarctic Sound, as well as off the South Orkney Islands in the austral summer of 2022 are discussed. Data were obtained on the association of the main abiotic environmental factors and their values, which are optimal for juvenile and mature krill individuals, and a number of abiotic environmental factors that affect the distribution of Antarctic krill in the studied region were identified. The results of such statistical modeling are important for monitoring the state of Antarctic ecosystems and their components under changing environmental factors, including current trends in climate change.
