Suspended particulate matter (SPM) as a main proxy of sedimentation conditions has potential to improve the study and monitoring of the consequences of rapid warming of the Arctic. In this study, we report the concentration of SPM and its major phase composition in the South Kara sedimentary basin in September 2022 as part of a climate experiment to investigate the composition of air and characteristics of the underlying surface in the Russian region of the Arctic and Siberia. In order to understand the sources, sinks, and hydrodynamic influences on SPM distribution in the South Kara Sea, three sections were carried out during cruise: longshore coastal section at the Priyamal shelf and two zonal sections through the center of the study area. These sections of SPM were overlain by salinity, temperature, turbidity, and chlorophyll-a fluorescence contours. Full depth profiles of SPM mass and volume concentrations obtained by a set of methods demonstrate layers of particle accumulation at density interfaces in the upper water column and widespread distribution of near bottom nepheloid layers. Particle composition and chlorophyll-a concentration analyzed from filtered samples throughout the water column aided considerably in determining the sources and distribution of SPM.
