From February 1st to March 23rd, a team comprising members from various research institutions worldwide will embark on GO-SHIPs A13.5 CO2 Hydrography Cruise. The purpose of the cruise is to conduct research on quantifying changes in ocean heat content, inorganic and organic carbon, oxygen, nutrients, and other natural and man-made tracers of ocean circulation in international waters. Equipped with state-of-the-art technology and onboard laboratories, this team will gather and analyze data of water columns cross multiple latitudes.
