These data were collected using a redundant, quasi-three-component electric field sensors carried by the autonomous underwater vehicle (AUV) Sentry during an expedition to the Escanaba Trough in the northeast Pacific Ocean in 2022 (USGS Field Activity 2022-621-FA). A SP map was generated by using equivalent point sources to represent the electric field data and using the equivalent point sources to compute a representative potential. These data are available as a GeoTIFF float32 file.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P1359BKJ", "description": "Landing page for access to the data", "format": "XML", "mediaType": "application/http", "title": "Digital Data"}, {"@type": "dcat:Distribution", "description": "The metadata original format", "downloadURL": "https://data.usgs.gov/datacatalog/metadata/USGS.6a2b3e7a1ba49b815ce94909.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_6a2b3e7a1ba49b815ce94909", "keyword": ["Bathymetry and Elevation", "CMHRP", "Central Hill", "Coastal and Marine Hazards and Resources Program", "Escanaba Trough", "PCMSC", "Pacific Coastal and Marine Science Center", "U.S. Geological Survey", "USGS", "USGS:6a2b3e7a1ba49b815ce94909", "bathymetry", "bathymetry measurement", "electric field", "geoscientificInformation", "geospatial datasets", "marine geophysics", "metallic mineral resources", "mineral resources", "oceans", "sea-floor characteristics", "self-potential"], "modified": "2026-07-28T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-127.514841, 40.981920, -127.473402, 41.008992", "theme": ["geospatial"], "title": "Equivalent point source mapping of self-potential in the Escanaba Trough (Central Hill)"}
