Vertical distribution of nutrients and DOC in lake waters near Syowa Station, Antarctica
The vertical distribution of inorganic nutrients and DOC (dissolved organic carbon) was determined for two freshwater and three saline lakes near Syowa Station in January to February, 1977. In the freshwater lakes of O-like and Skallen Oike, the concentrations of nutrients were very low and their di...

The vertical distribution of inorganic nutrients and DOC (dissolved organic carbon) was determined for two freshwater and three saline lakes near Syowa Station in January to February, 1977. In the freshwater lakes of O-like and Skallen Oike, the concentrations of nutrients were very low and their distributions were vertically homogeneous. Saline lakes of Nurume and Suribati, were typically meromictic and anoxic below 10m depth. In the anoxic layers of these lakes, PO_4-P and NH_4-N were highly concentrated. These nutrients were probably originated from the decomposition of organic materials in the bottom sediments. The concentrations of nutrients in Lake Hunazoko, which is the most saline lake around Syowa Station, were considerably lower than those of Lakes Nurume and Suribati except for SiO_2-Si.
