Concentrations of particulate organic carbon in the Kara Sea and in the Obskaya Guba (Ob River estuary) in September 1993
Contents and distribution of particulate lipids were studied by thin-layer chromatography technique with flame ionization detection (Iatroscan TH-10) along the transect from the Ob River towards the Kara Sea. Lipid contents range from 18.4 to 266 µg/l with, average 84.97 µg/l, which comprises from 4...
