Abstract
The article summarizes data on the suspended particulate matter content and dissolved and particulate organic carbon concentrations in Kara Sea water for 2007–2022. A difference in the distributions of dissolved (DOC) and particulate (POC) organic carbon in the water column during autumn (September) and spring–summer (July–August) was revealed. An increase in dissolved organic carbon concentrations was recorded both on the surface and in the water column in summer. Analysis of the dependences of DOC concentrations on salinity showed that the increase in these concentrations is not associated with an increase in DOC concentrations in river runoff water. There was also a significant increase in DOC and POC concentrations in phytoplankton bloom zones throughout the water column. Thus, a relationship has been identified between seasonal increases in organic matter concentrations in the open part of the sea and phytoplankton bloom processes.
期刊介绍：
Oceanology, founded in 1961, is the leading journal in all areas of the marine sciences. It publishes original papers in all fields of theoretical and experimental research in physical, chemical, biological, geological, and technical oceanology. The journal also offers reviews and information about conferences, symposia, cruises, and other events of interest to the oceanographic community.
