Organic Compounds and Suspended Particulate Matter in Snow of High Latitude Areas (Arctic and Antarctic)
Long-term studies of suspended particulate matter (SPM) and organic compounds (OCs)—C org , lipids, hydrocarbons (aliphatic—AHCs and polycyclic aromatic—PAHs), and chlorophyll a in the snow cover of the Arctic (Franz Victoria Trough, Mendeleev Rise, White Sea) and Antarctica (in the coastal waters o...
