Cruise>Climate Variability and Predictability (CLIVAR) A22,A20 (AT20, EM122)

The hydrographic surveys will consist of approximately 180 full water column CTD/LADCP casts along the trackline. Each cast will acquire up to 36 water samples on the upcast, which will be analyzed for salinity, oxygen, and nutrient concentrations. Water samples will also be analyzed during the cruise for dissolved inorganic carbon (DIC), pH, total alkalinity and transient tracers (CFCs and SF6). Additional water samples will be collected and stored for shore-based analysis of dissolved organic carbon (DOC), helium/tritium, 13C/14C, and chromophoric dissolved organic matter (CDOM). Underway measurements will include surface pCO2, temperature, conductivity, dissolved oxygen, fluorescence, various meteorological parameters, and bathymetry.
