Level 1 data (Required)

US GO-SHIP Level 1 measurements are core measurements (required with stringent data policy and timeline for submission of data):

  • Dissolved inorganic carbon (DIC)
  • Total Alkalinity (TAlk)
  • pH
  • CTD pressure, temperature, salinity (calculated)
  • CTD oxygen (sensor)
  • Bottle salinity
  • Nutrients by standard auto analyzer (NO3/NO2, NO2, PO4, SiO3)
  • Nitrate NO3 (calculated)
  • Dissolved oxygen
  • Chlorofluorocarbons (CFC-11, -12) and SF6
  • Dissolved organic carbon
  • Total dissolved nitrogen
  • Surface underway system (T, S, pCO2)
  • ADCP shipboard
  • ADCP lowered
  • Underway navigation and bathymetry
  • Meteorological
