Creed. The objective of the multiple echosounder surveys was to map the bathymetry and surficial sediments over time as dredged material was placed in the HARS to remediate contaminated sediments. Maps derived from the multibeam surveys show sea-floor bathymetry, shaded-relief bathymetry, and backscatter intensity (a measure of sea-floor texture and roughness) at a spatial resolution of 3 meters. The area was mapped by the U.S. Geological Survey in cooperation with the U.S. Army Corps of Engineers and with support from the Canadian Hydrographic Service and the University of New Brunswick.", "distribution": [{"@type": "dcat:Distribution", "description": "The metadata original format", "downloadURL": "https://data.usgs.gov/datacatalog/metadata/USGS.58826259e4b0dc04318b6dde.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}, {"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/F74B2ZGX", "description": "Landing page for access to the data", "format": "XML", "mediaType": "application/http", "title": "Digital Data"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_58826259e4b0dc04318b6dde", "keyword": ["imageryBaseMapsEarthCover", "U.S. Army Corps of Engineers (USACE)", "University of New Brunswick (UNB)", "multibeam sonar", "geospatial datasets", "3-m grid", "Simrad EM 1000", "Hudson Shelf Valley", "elevation", "Middle Atlantic Bight", "sea-floor characteristics", "Woods Hole Coastal and Marine Science Center (WHCMSC)", "marine geophysics", "North Atlantic Ocean", "USGS:58826259e4b0dc04318b6dde", "Open-File Report 00-503", "sea floor", "Canadian Coast Guard ship (CCGS) Frederick G.
