Biogeochemical components from underway water sampling system from CTD Data from T/S Oshoro maru 2023 Arctic Cruise / C145

To understand biogeochemical characteristic of the surface water in the Chukchi Sea, we collected surface seawater samples from underway water sampling system. We analyzed the biogeochemical parameters (Dissolved Inorganic Carbon (DIC), Total Alkalinity (TA), Nutrients, stable oxygen isotopic ratio, Colored Dissolved Organic Matter (CDOM), and High Performance Liquid Chromatography (HPLC)).
