Water-column environmental variables and accompanying discrete CTD measurements collected offshore the U.S. Mid- and South Atlantic (ver. 2.0, July 2022)	SBE 19plus V2 SeaCAT Profiler CTD	Various water column variables, including salinity, dissolved inorganic nutrients, dissolved inorganic carbon, and radio-carbon isotopes were measured in samples collected using a Niskin-bottle rosette at selected depths from deepwater sites offshore the US Mid- and South Atlantic from September 2017 to April 2019. CTD (Conductivity Temperature Depth) data were also collected at each depth that a Niskin-bottle sample was collected and are presented along with the water sample data during the following five cruises: PC1704 (USGS field activity 2017-004-FA) in September 2017, ENG615 (USGS field activity 2018-024-FA) in June 2018, AT41 (USGS field activity 2018-042-FA) in August 2018, BMCC-2018 (USGS field activity 2018-053-FA) in October 2018, and RB1903 (USGS field activity 2019-620-FA) in April 2019. This data release supersedes version 1.0, published in March 2021 at https://doi.org/10.5066/P9V7ODDR. Versioning details are documented in the accompanying VersionHistory_P9K2GOAL.txt file.
