        <gco:CharacterString>Chemical, physical and profile oceanographic data were collected aboard NOAA Ship GORDON GUNTER in the Gulf of Mexico from 2010-07-25 to 2010-07-31 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 conductivity, dissolved oxygen, hydrostatic pressure, salinity, sound velocity, temperature and water density. The instruments used to collect these data included CTD and oxygen meter along with other physical sampling devices. More specific information about each dataset is located in their individual metadata records. 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). 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.</gco:CharacterString>
      </gmd:abstract>
      <gmd:purpose>
        <gco:CharacterString>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 Deepwater Horizon oil spill.</gco:CharacterString>
