Intertidal and Subtidal Sea Otter Prey Sampling in Mixed Sediment Habitat in Glacier Bay National Park and Preserve, Alaska, 1998 to 2011

This dataset provides clam species abundance and size data from intertidal and subtidal mixed sediment habitats in Glacier Bay National Park and Preserve (GBNPP). Data are provided for all observed clams, horse mussels, or urchins 14 mm or larger. Sampling involved excavating 25 cm of substrate from quadrats (approximately 0.25 sq meter) along transects at random and selected sites, 10 quadrats at the 0 Mean Lower Low Water (MLLW) tide level for intertidal sampling and 20 quadrats at approximately 9 m depth for subtidal sampling. Site and taxonomic information are provided. Abundance and size data are provided in two tables with different data configurations: (1) a compact version with data for those species observed...

Bioenergetics and Morphology of Mussels (Mytilus trossulus) in Kenai Fjords National Park

This dataset provides one table of bioenergetic and morphological measurements of Pacific blue mussels (Mytilus trossulus; N = 444) collected at three intertidal sites in Kenai Fjords National Park, Alaska. Mussels were collected at the same tidal height across all three sites on a nearly monthly basis from 2014-2015.

This data release includes 2 child items with tracking data for Surf Scoters, a seaduck species that breeds throughout higher latitudes of Alaska and Canada and winters along coastal areas of North America. Child Item 1: "Argos Satellite Tracking Data for Surf Scoters (Melanitta perspicillata) - Processed Data" Quality-controlled data collected from Argos satellite transmitters. Child Item 2: "Argos Satellite Tracking Data for Surf Scoters (Melanitta perspicillata) - Raw Data" All raw data collected from Argos satellite transmitters, provided for completeness of the archive. The "Argos Processed Data" (Child Item 1) are better suited for most analytical purposes.

Child Item 2: Argos Satellite Tracking Data for Surf Scoters (Melanitta perspicillata) - Raw Data

This metadata document describes the data contained in the "Argos Raw Data" (Child Item 2) of this data release. This data release contains all data collected by the Argos System from 25 satellite transmitters attached to Surf Scoters on their winter ranges in southeast Alaska and Baja California, Mexico, 2005-2008. Five data files are included in the "Argos Raw Data" (Child Item 2) of this data release. Two data files (with identical content) contain the raw Argos DIAG (Diagnostic) data, one in the legacy verbose ASCII format and one in a tabular Comma Separate Value (CSV) format. Two other data files (with identical content) contain the raw Argos DS (Dispose) data, one in the legacy verbose ASCII format and one...

Genetic Data from Barrow's Goldeneye and Common Goldeneye

This data set describes nuclear microsatellite genotypes derived from eight autosomal loci (Aph02, Aph11, Aalµ1, Sfiµ4, Smo4, Smo7, Smo12, and Sfiµ8) and accession numbers for double digest restriction-site associated DNA (ddRAD) sequences.
