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 - Gulf of Mexico Regional Node. The effort is part of the annual Southeast Area Monitoring and Assessment Program's (SEAMAP) summer ground fish 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 is to develop new near-real time map products using shipboard measurements of bottom dissolved oxygen that would form the basis for summertime advisories on anoxic and hypoxic conditions in the North-central Gulf of Mexico and disseminate the data over the Internet. The survey follows a predetermined stratified random survey design to sample fishes and invertebrates in trawls, bongo and neuston nets, and 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 2006 summer ground fish cruise, approximately 200 stations will be sampled from June 14th through July 17th assuming that the cruise schedule is not disrupted by equipment problems or weather.

The USGS provides scientific information to support management actions intended to reduce excess nutrients in the Mississippi River Basin and Hypoxia in the Gulf of Mexico. USGS has participated in the Mississippi River/Gulf of Mexico Watershed Nutrient Task Force since its inception in 1997.

The EPA conducted an analysis of point source nutrient loadings in the Mississippi River System to support the White House Committee on Environment and Natural Resources' (CENR) Gulf of Mexico Hypoxia Working Group efforts to assess the causes and consequences of hypoxia in the Gulf of Mexico. Two documents provide the procedures used and a summary of the data collected.

National Ocean Service

As one of five NOAA Line Offices, NOAA's National Ocean Service (NOS) works to observe, understand, and manage our nation's coastal and marine resources. NOS measures and predicts coastal and ocean phenomena, protects large areas of the oceans, works to ensure safe navigation, and provides tools and information to protect and restore coastal and marine resources.

In providing these services, NOS works closely with its NOAA partners: the National Weather Service, Oceanic and Atmospheric Research, National Marine Fisheries Service, National Environmental Satellite Data and Information Service, and NOAA Marine and Aviation Operations. Such partnerships are important to achieving a "one NOAA" vision. Partnerships can also bring a broader range of experience, knowledge, and skill to the table—to develop tools and services that benefit a greater number of people and solve complex resource management problems.

LUMCON provides coastal laboratory facilities to Louisiana universities, and conducts in-house research and educational programs in the marine sciences. LUMCON's primary facilities are located at the DeFelice Marine Center in Cocodrie, approximately 85 miles southwest of New Orleans. This location, situated within the estuarine wetland complex of the Mississippi River delta plain between the Atchafalaya and Mississippi Rivers, provides ready access to the most productive estuaries in the United States, to a variety of coastal environments, and to the open Gulf of Mexico. To provide additional access to special environments, a field station is maintained at Port Fourchon.
