Recent data on the lipid composition in suspended matter from the intermediate area between the Kara and Laptev seas

Chemical group composition of suspended matter lipids from the intermediate zone between the Kara and Laptev seas is studied by thin-layer chromatogra phy with dame ionization detection (IATROSCAN TH-10). The basic components of the suspended matter lipids are hydrocarbons and complex polar lipids, s imilar to those found in the previously studied southeastern area of the Ka ra Sea. The high content of triglycerides in the upper layers of the water mass north of the Severnaya Zemlya islands is a characteristic feature of t he group composition of suspended matter lipids. The distribution of trigly cerides correlates with the localization of the ice cover limit, and compli es with the process of phytoplankton blooming in the ice edge zone. The dis tribution of the lipid content is determined by water stratification in the intermediate zone between the Kara and Laptev seas.
