Discrete bottle dissolved inorganic carbon (DIC), total alkalinity (Talk), water temperature and salinity validation data for the First Landing MAPCO2 system located in the mouth of the Chesapeake Bay, North Atlantic Ocean (36.9981 N, -76.0873 W) from 2018-05-02 to 2020-10-06 (NCEI Accession 0250708)

Published by NOAA National Centers for Environmental Information | National Oceanic and Atmospheric Administration, Department of Commerce | Catalog Last Checked: August 03, 2026 at 04:05 AM | Dataset Last Updated: April 01, 2022 at 12:00 AM
This dataset contains discrete bottle sample data for total Dissolved Inorganic Carbon (DIC) and Total Alkalinity (TAlk), water temperature and salinity samples, collected for validation and internal consistency analyses at the First Landing MAPCO2 system in the mouth of the Chesapeake Bay (36.9981 N, -76.0873 W). Samples were collected and immediately preserved with 0.2 µL of saturated Mercuric Chloride from 2018-05-02 to 2020-10-06. Samples were transported to the Cai-Laboratory at the University of Delaware for analysis. DIC is analyzed via a nondispersive infrared laser LICOR analyzer after 1 ml of 10% H3PO4 is injected into the sample and the CO2 gas is “stripped” out. TAlk is measured via Gran titration with HCl to an end-point of pH 3.2. The method precision is >0.1%. This effort was conducted in support of the coastal monitoring and research objectives of the NOAA Ocean Acidification Program (OAP).
