This comparative study discusses the concentration and major phase composition of suspended particulate matter (SPM) derived from observations collected in the White, Barents and Kara seas in 2001-2021. A selective synthesis is based on our field data on SPM concentrations obtained from water samples and optical data determined from beam attenuation coefficient and light scattering revealed a pronounced difference of seawater optical properties of the western Arctic shelf of Eurasia. The heterogeneous origin of SPM in the studied Arctic seas largely determines different particle size distribution (PSD) and major phase composition of particulate matter in this region. This impacts the optical properties of the water column and hence primary production and sedimentation processes on the western Eurasian Arctic shelf. In recent decades, the dramatic changes in the Arctic climate system, including sea ice, affecting the concentration and composition of SPM as well as optical properties of sea water on the Barents Sea shelf becomes close to ice-free and seasonally ice-free shelves of the White and Kara seas. A pronounced benthic nepheloid layer (BNL) was reveled widespread in the studied seas but it has different thickness and SPM concentration. SPM distribution in the euphotic zone of the seas is much differs due to mostly various catchment-derived material, including river discharge (particulate and dissolved), and other natural geographical conditions. It is necessary to develop regional and seasonal algorithms linking in situ data with remote sensing of bio-optical characteristics of sea water of the Eurasian Arctic shelf.

“…Repeatedly, the influence of smoke aerosol arriving with long-range transport from forest fires has been traced in the change in the physico-chemical characteristics of the atmosphere of the Arctic region [1][2][3] . The ice and snow cover of the Kara Sea stratify incoming impurities and contribute to their spatial and temporal variability 4,5 . The main sources of air pollution in the Kara Sea are the estuaries of the Ob and Yenisei rive 6,7 .…”
