  Description:
    Abstract:
      The Contaminated Sediments Database for the Gulf of Maine provides a compilation and synthesis of existing data to help establish the environmental status of our coastal sediments and the transport paths and fate of contaminants in this region. This information, in turn, forms one of the essential bases for developing successful remediation and resource management policies.
      	The Contaminated Sediments Database for the Gulf of Maine provides a compilation and synthesis of existing data to help establish the environmental status of our coastal sediments and the transport paths and fate of contaminants in this region. This information, in turn, forms one of the essential bases for developing successful remediation and resource management policies
      	This product is the result of a collaborative effort of principal investigators from the U.S. Geological Survey Coastal and Marine Geology Program, Woods Hole Oceanographic Institution, the University of New Hampshire, Bigelow Laboratory for Ocean Sciences, the University of Massachusetts, and active participation from the U.S. Army Corps of Engineers, the U.S. Environmental Protection Agency, the Massachusetts Water Resources Authority, the National Oceanic and Atmospheric Administration, and other federal and state agencies. Funding was provided by participating institutions and the Gulf of Maine Regional Marine Research Program.
    Purpose: The purpose of this data layer is to release a subset of the Gulf of Maine Contaminated Sediments Database that can be used to interpret surficial sediment distribution off the northeastern U.S.

    Process_Step:
      Process_Description: Textural and lithologic data from the Gulf of Maine were clipped from the whole Gulf of Maine Contaminated Sediments Database in Excel and exported to an ASCII file.  Stations and sediment data were imported from the ASCII text file to an ArcView table. The table was later converted to an event theme and saved as the final shapefile.
