Biogeochemical components of sea ice from T/S Oshoro maru 2023 Arctic Cruise / C145

Floating small sea ice (brash ice) samples were collected with landing net in the Chukchi sea. Sea ice were cut into small size (1-2 kg) and melted in gas-tight bags in the low-temperature room (4degreeC). We analyzed biogeocemical parameters of melted samples (Salinity, Stable oxigen isotopic ratio (delta18O), Dissolved inorganic carbon (DIC), Total alkarinity (TA), Nutrients, Colored dissolved orgnic matter (CDOM), Chlorophyll a, and Turbidity).
