Dissolved inorganic carbon (DIC), total alkalinity, pH on total scale, discrete pCO2, chlorofluorocarbons (CFC11, CFC12), dissolved organic carbon (DOC), water temperature, salinity, dissolved oxygen, nutrients and other hydrographic and chemical variables collected from discrete samples and profile observations during the R/V Thomas G. Thompson cruise on GO-SHIP repeat section A20 (EXPOCODE 325020210316) in the North Atlantic Ocean from 2021-03-16 to 2021-04-16 (NCEI Accession 0258957)

Published by NOAA National Centers for Environmental Information | National Oceanic and Atmospheric Administration, Department of Commerce | Catalog Last Checked: August 03, 2026 at 04:11 AM | Dataset Last Updated: August 16, 2023 at 12:00 AM
This dataset includes discrete profile measurements of Dissolved inorganic carbon (DIC), total alkalinity, pH on total scale, discrete pCO2, chlorofluorocarbons (CFC11, CFC12), dissolved organic carbon (DOC), water temperature, salinity, dissolved oxygen, nutrients and other hydrographic and chemical variables collected from discrete samples and profile observations during the R/V Thomas G. Thompson cruise on GO-SHIP repeat section A20 (EXPOCODE 325020210316) in the North Atlantic Ocean from 2021-03-16 to 2021-04-16. GO-SHIP repeat transoceanic surveys (www.goship.org) provide full water column hydrographic observations with temporal and spatial resolutions adequate to resolve decadal variability in oceanic storage of heat, freshwater, carbon, oxygen, nutrients and transient tracers. Repeat hydrographic physical-biogeochemical measurements nominally along 52° 20’N in the North Atlantic Ocean enables scientists to better tackle important unresolved aspects of the Atlantic Ocean’s response to decadal scale variability and increases in both heat and carbon dioxide as a result of anthropogenic activities. The U.S. GO-SHIP A20 2021 hydrographic section revisited this line for the fourth time, with prior transects occurring in 1997, 2003, and 2012.
