Scats were collected at various sites on the Umpqua River and at Desdemona sand spit on the Columbia River. Apart from describing the diet of Pacific harbor seals in these regions, of special interest was to determine the level of predation by these seals on endangered or threatened salmonids (e.g., cutthroat trout; Oncorhynchus clarkii). Fecal samples were collected to examine the diet (and inter-annual changes therein) of Pacific harbor seals at Umpqua and Columbia Rivers. In addition to general diet information, data were used to describe the level of predation on endangered salmonid species (esp. cutthroat trout) by these seals. completed historicalArchive NOAA National Centers for Environmental Information ncei.info@noaa.gov https://www.ncei.noaa.gov/contact HTTPS NCEI Contact Information Information for contacts at NCEI. information pointOfContact asNeeded https://www.ncei.noaa.gov/access/metadata/landing-page/bin/gfx?id=gov.noaa.nodc:0139413 Preview graphic PNG 0139413 NCEI ACCESSION NUMBER 2015-12-15 publication biological data OTOLITH SPECIES IDENTIFICATION theme NODC DATA TYPES THESAURUS microscope instrument NODC INSTRUMENT TYPES THESAURUS biological laboratory analyses theme NODC OBSERVATION TYPES THESAURUS NOAA Alaska Fisheries Science Center, Marine Mammal Laboratory dataCentre NODC COLLECTING INSTITUTION NAMES THESAURUS NOAA Alaska Fisheries Science Center, Marine Mammal Laboratory dataCentre NODC SUBMITTING INSTITUTION NAMES THESAURUS North Pacific Ocean place NODC SEA AREA NAMES THESAURUS oceanography theme WMO_CategoryCode 2012-09-15 publication DOC/NOAA/NMFS/AFSC/MML > Marine Mammal Laboratory, Alaska Fisheries Science Center, National Marine Fisheries Service, NOAA, U.S. Department of Commerce dataCentre Global Change Master Directory (GCMD) Data Center Keywords 2026 revision 24 Earth Science Data and Information System, Earth Science Projects Division, Goddard Space Flight Center (GSFC), National Aeronautics and Space Administration (NASA) Greenbelt MD https://forum.earthdata.nasa.gov/app.php/tag/GCMD%2BKeywords HTTPS GCMD Keyword Forum Page Global Change Master Directory (GCMD). 2025.

Fecal samples were cleaned using nested sieves or a washing machine set on gentle cycle (Orr et al. 2003). Prey hard parts were separated from waste material and subsequently identified to the lowest taxon possible using a microscope, prey reference collection, and prey identification keys. Sizes of prey were determined from measurements of fish otoliths and cephalopod beaks. Sizes were measured using calipers or ocular micrometer. Measurements were used to estimate prey size from published regression equations. Data were entered into a database. Data analyses were performed to address research questions about Pacific harbor seal diet. More detailed methods are provided in Browne et al. 2002, Laake et al. 2002, Orr et al. 2004; Data Quality Information: Identifications and size measurements of prey were double checked before transcription. Difficult prey identifications were verified by an expert. Data entered into database were cross-checked with transcribed data (exact information for each field, number of entries) asNeeded Metadata are developed, maintained and distributed by NCEI. Updates are performed as needed to maintain currentness.
