摘要：

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.
