Chemical, physical and profile oceanographic data were collected aboard the RYAN CHOUEST in the Gulf of Mexico from 2010-07-11 to 2010-07-13 in response to the Deepwater Horizon Oil Spill event on April 20, 2010, by the Subsurface Monitoring Unit (SMU), which consisted of multiple government and corporate agencies. These data include Total Petroleum Hydrocarbons (TPH) and fluorescence. The instruments used to collect these data included CTD, fluorometer and gas chromatograph along with other physical sampling devices. More specific information about each dataset is located in their individual metadata records. The CTD data underwent preliminary quality assurance and control procedures at the National Coastal Data Development Center (NCDDC). This dataset also contains products created for use in real time analysis and decision support. These products may include charts, graphs, maps, plots, and GIS formatted data files. Cruise level information consisting of data management documents, cruise reports and plans, videos and pictures, and other miscellaneous documentation were gathered by the data managers. The Hydrocarbon Sensor Array data are raw and provisional.
