Partial pressure (or fugacity) of carbon dioxide, salinity and other variables collected from Surface underway observations using Carbon dioxide (CO2) gas analyzer, Shower head chamber equilibrator for autonomous carbon dioxide (CO2) measurement and other instruments from the GORDON GUNTER in the G

NODC Accession 0117697 includes Surface underway, chemical, meteorological and physical data collected from GORDON GUNTER in the Gulf of Mexico from 2008-04-03 to 2008-11-20. These data include AIR-SEA DIFFERENCE - PARTIAL PRESSURE (OR FUGACITY) OF CARBON DIOXIDE, BAROMETRIC PRESSURE, Partial pressure (or fugacity) of carbon dioxide - atmosphere, Partial pressure (or fugacity) of carbon dioxide - water, SALINITY and SEA SURFACE TEMPERATURE. The instruments used to collect these data include Carbon dioxide (CO2) gas analyzer and Shower head chamber equilibrator for autonomous carbon dioxide (CO2) measurement.

These data were collected by Rik Wanninkhof, Denis Pierrot and Kevin Sullivan of US DOC; NOAA; OAR; Atlantic Oceanographic and Meteorological Laboratory as part of the Gordon_Gunter_Coastal_Cruises_2008 data set. CDIAC assigned the following cruise ID(s) to this data set: 805 Leg 3, GU0801, GU0802 Leg 2, GU0802 Leg1, GU0804 Leg 2, GU0805 Leg 1 and GU0805 Leg 2.

The Global Coastal Carbon Data Project data includes the bottle (discrete) and surface (underway) carbon-related measurements from coastal research cruises, the data from time series cruises and coastal moorings. The coastal regions data are very important for the understanding of carbon cycle on the continental margins.
