Underway total alkalinity, water temperature, salinity and other variables collected from surface seawater during NOAA Ship Henry B. Bigelow cruises in the North Atlantic Ocean, U.S. East Coast in 2021 (NCEI Accession 0288836)

Published by NOAA National Centers for Environmental Information | National Oceanic and Atmospheric Administration, Department of Commerce | Metadata Last Checked: January 29, 2026 | Last Modified: 2024-02-09T00:00:00.000+00:00
This data package contains data measured using an autonomous total alkalinity titrator on board the NOAA Ship Henry B. Bigelow cruises in 2021. Data were collected from the ship's underway seawater supply during the seven hydrographic surveys, from March 12 to November 3, 2021. Spatial data coverage extends from the Gulf of Maine to Cape Hatteras. This effort was part of the NOAA Ocean Acidification Program (OAP) grant entitled "Optimizing Ocean Acidification Observations for Model Parameterization in the Coupled Slope Water". Along with total alkalinity, corresponding temperature and salinity measurements are included. Measurements of pCO2 taken on these cruises are available from NOAA's AOML.
