Underway total alkalinity, water temperature, salinity and other variables collected from surface seawater during NOAA Ship Henry B. Bigelow cruises in the East Coast of the U.S. in 2023 (NCEI Accession 0288992)

Published by NOAA National Centers for Environmental Information | National Oceanic and Atmospheric Administration, Department of Commerce | Metadata Last Checked: January 29, 2026 | Last Modified: 2024-02-16T00:00:00.000+00:00
This data package contains data measured using an autonomous, automated total alkalinity titrator on board NOAA Ship Henry Bigelow. Data were collected from the ship's underway seawater supply during the seven hydrographic surveys, from May 8 to October 10, 2023. 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 "Expanding near-shore carbonate measurements along the East-coast and Gulf of Mexico through multiple collaborations". Along with total alkalinity, corresponding temperature and salinity measurements are included. Measurements of pCO2 taken on these cruises are available from NOAA's Atlantic Oceanographic and Meteorological Laboratory.
