SUMMARY

SED Dataset 2_17_11: Seafloor Sediment Composition in Massachusetts Determined Using Point Data

This GIS data layer represents point coverage of seafloor sediment size and composition in Massachusetts territorial waters. The data were created by aggregating available sediment point data collected from the United States Geological Survey's (USGS) usSEABED, version 1.0, U.S. Geological Survey Data Series 118 (Reid 2005), the Massachusetts Water Resources Authority, the Massachusetts Division of Marine Fisheries, and the United States Environmental Protection Agency.

Sediment data were collected between 1884 to 2008 from a variety of published and unpublished sediment texture and other geologic data. As such, the data has a variety of different horizontal accuracies and sampling and analysis methodologies. The dataset includes relative data quality for each point.

These data were produced by the:
