Hypoxia Watch

Point of Contact


The Gulf of Mexico Hypoxia Watch evolved as a cooperative project among the National Oceanic and Atmospheric Administration's (NOAA's) National Marine Fisheries Service (NMFS), National Centers for Environmental Information at Stennis (NCEI), and the CoastWatch-Caribbean/Gulf of Mexico Regional Node. Hypoxia Watch provides near-real-time data and map products using shipboard measurements of bottom-dissolved oxygen. These products form the basis for summertime advisories on anoxic and hypoxic conditions in the north-central Gulf of Mexico.

This map provides a near-real-time, geospatially referenced view of dissolved oxygen measurements made during the annual summer Gulf of Mexico Southeastern Monitoring and Assessment Program (SEAMAP) cruise in the northwest and north-central Gulf of Mexico.

Personnel on the NOAA ship Oregon II send data packets to NCEI every 3-5 days during the cruise. We then process the data and make it available online for download through this map service. The site also makes data measurements available from previous years.
