Chemical, physical, profile and other oceanographic data collected aboard the RYAN CHOUEST in the Gulf of Mexico from 2010-10-07 to 2010-10-17 in response to the Deepwater Horizon Oil Spill event (NCEI Accession 0069356)

Published by NOAA National Centers for Environmental Information | National Oceanic and Atmospheric Administration, Department of Commerce | Metadata Last Checked: October 13, 2025 | Last Modified: 2021-10-15T00:00:00.000+00:00
Chemical, physical, profile, imagery, laboratory analysis and sediment analysis oceanographic data were collected aboard the RYAN CHOUEST in the Gulf of Mexico from 2010-10-07 to 2010-10-17 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 CDOM fluorescence, Carbon - Total Organic, Metals, Semivolatile Organic Compounds, Total Petroleum Hydrocarbons (TPH), Volatile Organic Compounds, conductivity, dissolved oxygen, hydrostatic pressure, salinity, sediment properties, sound velocity, temperature and water density. The instruments used to collect these data included CTD, bottle, fluorometer, oxygen meter and sediment sampler - corer along with other physical sampling devices. More specific information about each dataset is located in their individual metadata records. Sediment cores were analyzed for physical characteristics, and recorded in photos and data files. 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. The CTD data underwent preliminary quality assurance and control procedures at the National Coastal Data Development Center (NCDDC). The analytical chemistry data are provisional and provide results of onshore laboratory analysis of water and sediment samples. 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.
