Discrete surface underway measurements of dissolved inorganic carbon (DIC), total alkalinity (TA), pH (SWS), water temperature, salinity, dissolved oxygen, nutrients, partial pressure of carbon dioxide (pCO2) and other parameters during the NOAA Ship Ronald H. Brown GO-SHIP A13, A12 2020 section cruises (EXPOCODEs 33RO20200221; 33RO20200321) in the North and South Atlantic Ocean from 2020-02-21 to 2020-04-17 (NCEI Accession 0308013)

This dataset contains discrete underway and surface (above 10dbar) CTD bottle measurements collected during the NOAA Ship Ronald H. Brown Global Ocean Ship-Based Hydrographic Investigations Program (GO-SHIP) sections A13.5, A12 cruises in the North and South Atlantic Ocean from 2020-02-21 to 2020-04-17. There were 8 surface CTD measurements collected from Niskin Bottles and 330 discrete underway samples collected via a continuously flowing underway line. Discrete underway data has typically not been reported and the purpose of this dataset is to collate unpublished and published surface measurements together from the same research cruise in a usable format. Parameters include water pressure, water temperature, salinity, dissolved oxygen, DIC, TA, pH (SWS), pCO2, silicate, nitrite, nitrate and phosphate.
