Abstract
The goal of the work: assessment of summer oceanographic conditions of the Barents and Kara Seas.
Materials and methods: the data presented in the work were obtained on the 96rd cruise of the R/V «Akademik Mstislav Keldysh» (July 25, 2024–August 31, 2024). During the expedition, hydrological and chemical characteristics (temperature, salinity, dissolved oxygen, silicates, mineral and organic forms of nitrogen and phosphorus and dissolved organic carbon) were measured from the surface to the bottom. Chemical analysis was carried out in the ship’s laboratory, according to certified methods for sea and fresh waters. Dissolved organic carbon samples were using a filtration through membrane filters (0.45 μn) and fixed with hydrochloric acid for further determination using high-precision TOC–L equipment in a stationary laboratory in Moscow. In total, 13 oceanological sections and 183 complex oceanological stations were completed.
The practical significance of the research: assessment of the production potential of the economically significant seas of the European Arctic for Russia in the area of maximum climate changes, replenishment of the monitoring system of hydrological and biogeochemical characteristics based on ship observations in accordance with the Order of the Government of the Russian Federation of October 29, 2022 No. 3240-r.
