This data package contains Underway total alkalinity, water temperature, salinity and other variables collected from surface seawater during the NOAA Ship Ronald H. Brown GOMECC2021 cruise RB2103 (EXPOCODE 33RO20210913) in the Gulf of Mexico, North Atlantic Ocean from 2021-09-13 to 2021-10-21. Data were collected from the ship's underway seawater supply during the GOMECC-4 cruise. This effort was part of the NOAA Ocean Acidification Program (OAP) grant entitled "Expanding near-shore carbonate measurements along the East-coast and Gulf of Mexico through multiple collaborations". Along with total alkalinity, corresponding temperature and salinity measurements are included. Measurements of pCO2 taken on these cruises are available from NOAA's AOML.

This dataset contains surface discrete measurements of dissolved inorganic carbon, total alkalinity, water temperature, salinity and other variables collected from surface discrete observations using flow through pump, CTD, Niskin Bottles and other instruments during NOAA Ship Ronald H. Brown cruise RB10-07 (EXPOCODE 33RO20101014), in the Gulf of Mexico from 2010-10-14 to 2010-11-04. Increasing amounts of atmospheric carbon dioxide from human industrial activities are causing changes in global ocean carbon chemistry. Through the SOOP program we measure air and ocean surface pCO2 and take discrete samples of other carbon parameters. This effort is in support of the coastal monitoring and research objectives of the NOAA Ocean Acidification Program (OAP) and the Climate Program Office.

This data package contains Underway total alkalinity, water temperature, salinity and other variables collected from surface seawater during the NOAA Ship Ronald H. Brown 2022 East Coast Ocean Acidification cruises (ECOA2022) (EXPOCODEs 33RO20220806, 33RO20220906) in the North Atlantic Ocean, U.S. East Coast from 2022-08-06 to 2022-09-23. Data were collected from the ship's underway seawater supply. This effort was part of the NOAA Ocean Acidification Program (OAP) grant. Along with total alkalinity, corresponding temperature and salinity measurements are included. Measurements of pCO2 taken on these cruises are available from NOAA's AOML.

This data package contains Underway total alkalinity, water temperature, salinity and other variables collected from surface seawater during the NOAA Ship Ronald H. Brown 2021 West Coast Ocean Acidification cruise RBWCOA2021 (EXPOCODE 33RO20210613) in the North Pacific Ocean from 2021-06-14 to 2021-07-20. Data were collected from the ship's underway seawater supply during the NOAA Ocean Acidification Program-funded West Coast Ocean Acidification (WCOA) cruise. This underway TA effort was part of the NOAA Ocean Acidification Program (OAP) grant entitled "Expanding near-shore carbonate measurements along the East-coast and Gulf of Mexico through multiple collaborations". Along with total alkalinity, corresponding temperature and salinity measurements are included. Measurements of pCO2 taken on these cruises are available from NOAA's AOML.

This dataset contains profile discrete measurements of dissolved inorganic carbon, total alkalinity, water temperature, salinity and nutrients collected from profile discrete observations using CTD, Niskin Bottles and other instruments during the NOAA Ship Nancy Foster cruise NF10-13 (EXPOCODE 33NF20100701), in the Gulf of Mexico from 2010-07-01 to 2010-07-18. Increasing amounts of atmospheric carbon dioxide from human industrial activities are causing changes in global ocean carbon chemistry. Through the SOOP program we measure air and ocean surface pCO2 and take discrete samples of other carbon parameters. This effort is in support of the coastal monitoring and research objectives of the NOAA Ocean Acidification Program (OAP) and the Climate Program Office.

This dataset includes surface underway measurements of mole fraction of CO2 in the equilibrator headspace (dry) at equilibrator temperature, mole fraction of CO2 measured in dry outside air, barometric pressure in the equilibrator headspace, barometric pressure, corrected to sea level, water temperature in equilibrator, sea surface temperature, sea surface salinity, fugacity of CO2 in sea water at SST and 100% humidity, and difference between sea water fCO2 and interpolated air fCO2 measured during the NOAA Ship Gordon Gunter cruises in the Gulf of Mexico and North Atlantic Ocean in 2022. The instruments used to collect these data include carbon dioxide (CO2) gas analyzer and shower head chamber equilibrator for autonomous carbon dioxide (CO2) measurement.

This dataset includes surface underway, chemical, meteorological and physical data collected during NOAA Ship Gordon Gunter cruises in the Gulf of Mexico and North Atlantic Ocean from 2016-04-10 to 2016-11-22. These data include partial pressure (or fugacity) of carbon dioxide - atmosphere, partial pressure (or fugacity) of carbon dioxide - water, sea surface temperature, sea surface salinity and barometric pressure. 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 NOAA Atlantic Oceanographic and Meteorological Laboratory as part of the Gordon_Gunter_Coastal_Cruises_2016. 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.
