Carbon contribution of sea ice floes in the Arctic Ocean
To estimate detailed contributions of particulate organic carbon (POC) as a potential food source in various environments of the Arctic sea ice floes, intensive investigations were executed at two different types of sea ice stations (ST I and ST 2) in the northern Chukchi Sea during the summer perio...
