Cruise 15, Summary of data collected from the R/V Ocean Veritas, August 18-22, 2010] [electronic resource] / [U.S. Dept. of Commerce, National Oceanic and Atmospheric Administration ; U.S. Environmental Protection Agency ; BP]. [2010]

Collection of documents and data online in JPEG, Microsoft Excel, Microsoft Word, PDF, and PNG formats obtained during R/V Ocean Veritas cruise 15 for the NOAA Subsurface Monitoring Unit (SMU) activities related to the Deepwater Horizon incident response, August 18-22, 2010, Mississippi Canyon 252 area, Gulf of Mexico. Collection includes status reports, data reports, images, SMU data management documents, requirements, and guidance, including sample station locations maps, sample log, sample inventory, navigation logs, and equipment list. Products may include geospatial data files, maps, charts and/or data plots or graphs. Datasets associated with this cruise will be processed and published as they become available. Data also available via the National Oceanographic Data Center, Ocean Archive System (OAS) database, NODC Accession 0069105. Chemical, physical, profile and laboratory analysis oceanographic data were collected aboard the Ocean Veritas in the Gulf of Mexico from August 18-22, 2010, 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 Attenuation/Transmission, CDOM fluorescence, Semivolatile Organic Compounds, Total Petroleum Hydrocarbons (TPH), Volatile Organic Compounds, conductivity, dissolved oxygen, hydrostatic pressure, salinity, sound velocity, suspended solids, temperature and water density. The instruments used to collect these data included CTD, Laser In-Situ Scattering and Transmissometer (LISST), Transmissometer, bottle, fluorometer and oxygen meter along with other physical sampling devices. 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. The Subsurface Monitoring Unit (SMU) was formed by US Federal Government Agencies NOAA and EPA working with BP as part of the coordinated response to the Deepwater Horizon Oil Spill (MC252 incident) in the Gulf of Mexico in April 2010. The SMU coordinated DWH response data collection and sampling efforts across Academia, private and US Federal, State and International agencies and scientists. The goal of the data collection and sampling efforts was to support comprehensive characterization of the Gulf of Mexico sub-surface conditions as well as the fate and transport of dispersed petroleum as a result of the Deep Water Horizon oil spill.
