Particulate matter and organic compounds in snow, ice, and water of the Lazarev and Cooperation Seas

Integrated studies of particulate matter and organic compounds in surface waters and the snow-ice cover by means of geochemical (concentrations of the particulate matter, Corg, hydrocarbons, lipids, and chlorophyll a) and optical techniques were performed in the Southern Ocean and in the East Atlantic Ocean along the vessel's route: Africa - Antarctica - Africa - St. Petersburg. Correlations between studied compounds were found. It was shown that supply of pollutants affects not only concentrations but also proportions of the considered compounds. New data were obtained on the processes of accumulation of particulate matter and organic compounds under ice formation.

本研究采用地球化学技术（涵盖颗粒物浓度、有机碳（Corg）、烃类、脂类及叶绿素a的测定）与光学技术，沿非洲-南极洲-非洲-圣彼得堡的船舶航行航线，于南大洋及东大西洋海域开展了表层海水与冰雪覆盖层内颗粒物及有机化合物的综合探测研究。研究结果表明，目标化合物间存在显著相关性；污染物输入不仅会改变所研究化合物的浓度水平，还会影响其相对占比。同时，本研究获取了冰形成过程中颗粒物与有机化合物积累过程的全新观测数据。
