The 4125 Towfish utilizes EdgeTech\u2019s Full Spectrum CHIRP technology to produce higher resolution images than a non-CHIRP system. EdgeTech Discovery Software was used to acquire the side scan sonar data using the JSF format at a resolution of about 2.3 cm. All JSF files collected using EdgeTech\u2019s Discover Software were processed using John Gann\u2019s Chesapeake Technology SonarWiz5. Dimensions of contacts should be considered accurate to +/- 30% of the measured dimensions. This system also records the direct arrival intensity data.", "distribution": [{"@type": "dcat:Distribution", "description": "Cruise track lines in ESRI shapefile (.shp) format", "downloadURL": "https://irma.nps.gov/DataStore/DownloadFile/647257?Reference=2278681", "format": "zip", "mediaType": "application/zip", "title": "SH_tracklines.zip"}], "identifier": "http://datainventory.doi.gov/id/dataset/NPS_DataStore_2278681", "issued": "2017-02-10T00:00:00Z", "keyword": ["Benthic Ecology", "GATE", "Gateway National Recreation Area", "Hurricane Sandy", "HxSandy", "NCBN", "New Jersey", "Northeast Coastal and Barrier Network", "Sandy Hook", "Seafloor", "Seafloor Mapping", "Sediment", "Sidescan Sonar", "bathymetry", "benthic habitat", "benthic habitat mapping", "marine Geology", "submerged habitat", "submerged habitat mapping"], "landingPage": "https://irma.nps.gov/DataStore/Reference/Profile/2278681", "modified": "2017-02-10T00:00:00Z", "programCode": ["010:118", "010:119"], "publisher": {"@type": "org:Organization", "name": "National Park Service"}, "spatial": "-74.14016,40.3950768,-73.77641,40.65834", "temporal": "2015-07-01/2015-08-01", "theme": ["geospatial"], "title": "Cruise Track Lines, 2015, Gateway National Recreation Area"}
