Water temperature, salinity, dissolved oxygen, and other measurements from CTD taken in the northern Gulf of Mexico during the summers as part of the Southeast Area Monitoring and Assessment Program (SEAMAP) from 1992 to present

Published by NOAA National Centers for Environmental Information | National Oceanic and Atmospheric Administration, Department of Commerce | Catalog Last Checked: August 03, 2026 at 08:16 AM | Dataset Last Updated: August 11, 2025 at 12:00 AM
These datasets consist of profile data collected by CTD casts in the northern Gulf of Mexico that are collected as part of the annual summer groundfish survey supported by the Southeast Area Monitoring and Assessment Program (SEAMAP). SEAMAP is a State/Federal/university program for collection, management and dissemination of fishery-independent data and information in the southeastern United States. Data are in Sea-Bird CNV format.
