Chemical group composition of particulate lipids from the intermediate zone between the Kara and Laptev Seas is studied by thin-layer chromatography with flame ionization detection (IATROSCAN TH-10). Hydrocarbons and complex polar lipids similar to those found in the previously studied southeastern area of the Kara Sea are basic components of particulate lipids. High content of triglycerides in the upper layers of the water mass north of the Severnaya Zemlya Islands is a characteristic feature of group composition of particulate lipids. Distribution of triglycerides correlates with localization of the ice cover boundary and complies with process of phytoplankton blooming in the ice edge zone. Distribution of lipid concentration depends on water stratification in the intermediate zone between the Kara and Laptev Seas.
