Water temperature, salinity, oxygen, dissolved inorganic carbon, pH, and others collected by CTD and Niskin bottles from research vessel Hugh R. Sharp in Mid-Atlantic Bight from 2017-08-25 to 2017-09-03 (NCEI Accession 0209187)

Discrete measurements of natural radiocarbon of dissolved inorganic carbon (DIC), DIC concentration, pH, and methane concentration were acquired from Niskin bottles during conductivity-temperature-depth (CTD) casts.

The CTD casts were conducted along five MAB transects oriented roughly perpendicular to the shelf break and stretching from the upper slope to about 1,000 m depth. Five CTD stations were occupied on each transect, and samples were collected throughout the water column from the near-surface waters (~2 m depth) to within 5 m of the seafloor, when possible. Approximately 12 samples were collected in the water column at the location of each CTD cast, for a total of 293 successful water samples at the 25 stations.
