Amur River/Geochemical cycle Nutrient status of snow cover and sea ice in the southern Sea of
Samples of sea ice and snow cover on sea ice were collected with the icebreaker P/V Soya in early February 2007 in the southern Sea of Okhotsk in order to evaluate the amount of nutrients in the sea ice and snow. The concentration of nitrate + nitrite, phosphate and silicic acid in the samples was m...
