To release an interpretation of bottom features based on bathymetry data collected during NOAA survey H11997 and sediment samples and bottom photography collected during USGS survey 2010-015-FA offshore in eastern Long Island Sound, in a geographic, WGS84 coordinate system. These data can be used to provide information on surface geology and sedimentary processes.
Are there legal restrictions on access or use of the data?
