  abstract:
    en: 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.
