Thompson cruise on GO-SHIP repeat section A22 (EXPOCODE 325020210420) in the North Atlantic Ocean from 2021-04-20 to 2021-05-16 (NCEI Accession 0259287)",
    "description": "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 A22 (EXPOCODE 325020210420) in the North Atlantic Ocean from 2021-04-20 to 2021-05-16. 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\u00b0 20\u2019N in the North Atlantic Ocean enables scientists to better tackle important unresolved aspects of the Atlantic Ocean\u2019s response to decadal scale variability and increases in both heat and carbon dioxide as a result of anthropogenic activities. The A22 2021 cruise aboard the UNOLS vessel R\/V Thomas G. Thompson was undertaken as part of the US GO-SHIP (Global Ocean Ship-based Hydrographic Investigations Program), a major contributor to international GO-SHIP. The program\u2019s overall objective is to collect quasi-decadal, highly accurate, surface-to-bottom, coast-to-coast, physical, and chemical oceanic observations. These measurements are essential to monitoring long-term changes in heat, freshwater, carbon, oxygen, and other tracers in the global ocean, the main reservoir in the Earth System.",
