The spatial coverage includes the Gulf of Alaska, Bering Sea, Aleutian Islands, Chukchi Sea, and Beaufort Sea. Fish species within the database include Pacific sand lance, Pacific capelin, Pacific herring, juvenile walleye pollock and Pacific cod, myctophid, squid, and euphausiid. The data package is comprised of six tables: (1) catch_table includes counts, weight, and individual morphological characteristics (length, sex, age) of the sampled species; (2) event_table includes sampling time, location, and methods; (3) gear_table includes specifics about of the gear used for sampling when applicable; (4-5) two tables with taxonomic designations for forage species or predator species; and (6) a reference table that provides summary information about each contributed dataset.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P9WZQJ8N", "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.ASC607.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_ASC607", "keyword": ["Foraging behavior", "Forage fish", "Aleutian Islands", "Pacific herring", "Trophic relationships", "USGS:ASC607", "Trophic Dynamics", "Relative abundance analysis", "Chukchi Sea", "Alaska", "Environment", "Myctophid", "Seasonal distribution", "Biota", "Species life history", "Population dynamics", "Marine ecosystems", "Beaufort Sea", "Fisheries", "Food fishes", "Diets", "Range changes", "Bering Sea", "Squid", "Pacific cod", "Gulf of Alaska", "Sand lance", "Fish", "Pacific capelin", "Walleye pollock"], "modified": "2024-05-17T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-179.9900, 51.1855, -130.4756, 72.5035", "theme": ["geospatial"], "title": "Alaska Forage Fish Database (AFFD)"}
