This dataset includes discrete profile data collected during the R/V Rachel Carson cruises 201605CB, 201606CB, 201608CB, 201610CB (EXPOCODEs 32RC20160504, 32RC20160606, 32RC20160808, 32RC20161010) in the Chesapeake Bay and North Atlantic Ocean from 2016-05-04 to 2016-10-13. These data include dissolved inorganic carbon (DIC), total alkalinity (TA), temperature, salinity, dissolved oxygen and calcium ion measured from discrete bottles. The data are from the first bay-wide observational study of the main stem of the Chesapeake Bay. Four bay-wide cruises were conducted in the Chesapeake Bay on R/V Rachel Carson on May 4–6, June 6–10, August 8–12, and October 10–13, 2016, and one bay-wide cruise was on a commercial boat on February 21–22, 2019. The surface underway data from these cruises are archived at NCEI as Accession 0191507. The field research was supported by the U.S. National Oceanic and Atmospheric Administration, NOAA (NA15NOS4780190).
