Most Recent Measure Definition (From FY2010 or FY2010, if available):
Terms and Phrases:The hypoxia zone in the Gulf of Mexico is an area where seasonal oxygen levels drop too low to support most life in bottom and near-bottom waters. This hypoxic area is primarily caused by high nutrient levels which stimulate an overgrowth of algae that sinks and decomposes. The decomposition process in turn depletes dissolved oxygen in the water. The hypoxic zone is of particular concern because it threatens valuable commercial and recreational Gulf fisheries.
Methodology for Computation of Results:Essential components of the environmental monitoring program in the Gulf of Mexico include efforts to document the temporal and spatial extent of shelf hypoxia, and to collect basic hydrographic, chemical, and biological data related to the development of hypoxia over seasonal cycles.
Units:Square kilometers
Universe:n/a
Baseline:14,128 km² (FY 2005)
