CTD and routine analysis of seawter: T/S Oshoro-maru cruise, C56, 2018

Profiles of CTD and DO (SBE 9) , in-situ fluorescence (fluorometer, Seapoint), beam attenuation coefficient (C-Star, WET Labs), CDOM fluorescence (ECO, WET Labs) in the Northern Bering and Southern Chukchi Seas during the cruise of T/S Oshoro-maru in 2018 summer. Water samples were taken by Niskin bottles on the CTD and dissolved oxygen (DO), nutrients, salinity, dissolved inorganic carbon, chlorophyll a concentration, DIC of the seawaters were analyzed. Underway data (temperature, salinity, chlorophyll fluorescence, turbidity) was continuously recoded along the track.
