Physical and chemical data collected by bottle and CTD in the Gulf of Mexico from the R/V Gyre and R/V Pelican, April 2004 - July 2009 to help resolve the dominant oceanographic processes that control the timing, duration, and severity of hypoxia of the region (NCEI Accession 0088164)

Data were submitted from the project Mechanisms Controlling Hypoxia on the Louisiana Shelf. This data are part of a comprehensive and multidisciplinary study of the Texas-Louisiana Shelf that included interdisciplinary process cruises and shelf-wide surveys to complement, and provide rates and other parameters necessary for the initiation, control, and skill assessment of a realistic coupled three-dimensional hydrodyamic-biological-geochemical-sediment numerical modeling and statistical (multivariate) modeling elements.
