Users will find links to tracking data from other wildlife species. https://doi.org/10.5066/P9VYSWEH This data release includes 2 child items with tracking data for Marbled murrelets tagged in Washington state and Alaska, 2008 and 2013. Child Item 1: "Argos Satellite Tracking Data for Marbled Murrelets (Brachyramphus marmoratus - Processed Data" -- Quality-controlled data collected from Argos satellite transmitters. Child Item 2: "Argos Satellite Tracking Data for Marbled Murrelets (Brachyramphus marmoratus - Raw Data" -- All raw data collected from Argos satellite transmitters, provided for completeness of the archive. The quality-controlled, "Argos Processed Data" (Child Item 1) are better suited for most analytical purposes. These data were collected to better understand the timing and patterns of movements of Marbled murrelets along the north Pacific coast of North America. 2008 2013 observed Complete None planned North Pacific coast of North America 173.131 -120.306 61.588 47.086 USGS Metadata Identifier USGS:686eea41d4be020e5c01c3bb ISO 19115 Topic Category Biota Environment NASA GCMD Earth Science Keyword Thesaurus Animals/Vertebrates Birds Waders/Gulls/Auks and Allies Migratory rates/routes Species life history Telemetry USGS CSA Biocomplexity Thesaurus Migratory birds Seasonal distribution Seasonal movement Overwintering Breeding sites Capture-recapture studies Tracking equipment Tagging devices USGS Thesaurus Wildlife Ornithology Migratory species Coastal ecosystems Marine ecosystems Animal tracking None Pacific Americas flyway Satellite transmitter Platform Transmitter Terminal PTT Argos None Marbled murrelet Brachyramphus marmoratus USGS Geographic Names Information System (GNIS) Alaska Prince William Sound Attu Island Washington Puget Sound None Animals Vertebrates Birds Seabirds Marbled murrelet ITIS Integrated Taxonomic Information System Unknown online database online ITIS-North America Taxonomic details retrieved July 2, 2025 from the Integrated Taxonomic Information System online database https://www.itis.gov https://doi.org/10.5066/F7KH0KBK Species were identified by skilled observers in the field based on general appearance, plumage, behavior, and vocalization.
