Project Status: (20070808) - The 2007 SEAMAP survey has been declared finished. Unfortunately, because of ship and equipment problems, there are several gaps in the data this year. All available hypoxia data is available now for download and through the Interactive Map application. After QA/QC is finished, we plan to publish any adjusted data along with temperature and fluorescence profiles for the CTD casts.

The Gulf of Mexico Hypoxia Watch is a cooperative project among the National Oceanic and Atmospheric Administration's (NOAA) National Marine Fisheries Service (NMFS), the National Coastal Data Development Center (NCDDC), and the CoastWatch - Caribbean/Gulf of Mexico Regional Node. The effort is part of the annual Southeast Area Monitoring and Assessment Program's (SEAMAP) summer groundfish survey conducted by NMFS in the Western and North-central Gulf of Mexico aboard the NOAA Ship OREGON II. The site includes an Interactive Map of preliminary data products.

The objective of Hypoxia Watch is to develop new near-real time data and map products using shipboard measurements of bottom dissolved oxygen and to disseminate them over the Internet. These products form the basis for summertime advisories on anoxic and hypoxic conditions in the North-central Gulf of Mexico. The survey follows a predetermined stratified random survey designed to sample fish and invertebrates in trawls, bongo and neuston nets, and to acquire environmental data with an environmental profiler at stations located east of the Mississippi River and in the area between the 10 and 200 m isobaths from Brownsville, Texas eastward to the Mississippi River. The profiler is equipped with sensors to measure water temperature, salinity, dissolved oxygen, fluorescence, and transmittance continuously from the surface to the sea bottom. During the 2007 summer groundfish cruise, approximately 200 stations will be sampled from June 6th through July 15th, barring any disruption by equipment problems or weather.

The initial leg of the 2007 summer groundfish survey will begin on Wednesday, June 6th and will survey the area east of the Mississippi River and from Brownsville to Corpus Christi, Texas. Two additional cruise legs are planned for the area from Corpus Christi to the mouth of the Mississippi River. The detailed cruise schedule is provided on the 2007 Schedule page.

  Interactive Map
This mapping application 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. Near real-time data are received from the NOAA ship Oregon II twice weekly and are assimilated into a geospatially enabled database. Maps from previous years are also stored in a geospatially enabled database and are available through this site.
