USGS Leads a National Study on Hypoxia in the Gulf of Mexico
The USGS was the lead agency for a recently released national study on the Flux and Sources of
Nutrients in the Mississippi-Atchafalaya River Basin. This report is part of a multi-agency
assessment of the causes and consequences of hypoxia in
the Gulf of Mexico. Nutrients from the Mississippi River
Basin are believed to be responsible, at least in part, for the large hypoxic zone that develops on
the Louisiana-Texas shelf in the Gulf of Mexico each summer.
This map shows the
locations of the 9 large subbasins studied in the Committee on Environment and Natural Resources
(CENR) hypoxia assessment.
