Biogeochemical components from CTD Data from T/S Oshoro maru 2023 Arctic Cruise / C145

To understand biogeochemical characteristic of the seawater in the Chukchi Sea, we collected vertical seawater samples by using Niskin bottles mounted on the CTD/Carousel 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)).
