Dataset Overview | National Centers for Environmental Information (NCEI)

Surface underway measurements of partial pressure of CO2 (pCO2), sea surface temperature, sea surface salinity and barometric pressure collected during the Wave Glider GEOMAR-4 sail in the North Atlantic Ocean from 2021-11-14 to 2022-01-14 (NCEI Accession 0277801)

Preview graphic

This dataset includes surface underway, chemical, meteorological and physical data collected during the Wave Glider GEOMAR-4 sail in the North Atlantic Ocean from 2021-11-14 to 2022-01-14. These data include partial pressure (or fugacity) of carbon dioxide - atmosphere, partial pressure (or fugacity) of carbon dioxide - water, sea surface salinity, sea surface temperature and barometric pressure. A Wave Glider equipped with a VeGas CO2 system, a GPCTD and additional BGC sensors was deployed north of the CVOO site. The deployment served as a test of the VeGas systems performance as a possible cross reference tool for BGC_Argo floats as well as to study eddys in closer proximity to the islands.
