Satellite Telemetry Dataset (Raw): Juvenile Bearded and Spotted Seals, 2004-2006, Kotzebue, Alaska

Metadata Updated: May 1, 2024

Bearded seals (Erignathus barbatus) are one of the most important subsistence resources for the indigenous people of coastal northern and western Alaska, as well as key components of Arctic marine ecosystems, yet relatively little about their abundance, seasonal distribution, migrations, or foraging behaviors has been documented scientifically. Ice-associated seal populations may be negatively impacted by offshore oil and gas development as well as by climate change. During a cooperative effort between scientists and subsistence hunters in October 2004, 2005, and 2006, 13 female and 13 male juvenile (i.e., age <2) bearded seals (Erignathus barbatus) were tagged with satellite-linked dive recorders (SDRs) in Kotzebue Sound, Alaska. While the focus of this study was on young bearded seals, an additional three female spotted seal (Phoca largha) pups and two adult spotted seal males were captured and deployed with satellite telemetry devices.

The data files within this dataset represent the 'raw' data obtained from the Wildlife Computers data portal. Each deployment (unique tag id + animal id combination) is provided as a zipped archive. The root folder also includes additional documentation. The various files and detailed column descriptions are described in the 'Spreadsheet-File-Descriptions.pdf' which was downloaded from Wildlife Computers (https://wildlifecomputers.com/support/downloads/). The '00_kotzeb04_get_data.Rmd' file is an RMarkdown file that provides code and documentation of the data retrieval process. The corresponding '00_kotzeb04_get_data.hml' file is generated from the RMarkdown file.

Lineage All data provided are included as zipped archives that contain a variety of files processed on the Wildlife Computers Data Portal. The specific files included are dependent upon the tag hardware, firmware, and programming options selected. The files and column heading descriptions are provided in the 'Spreadhseet-File-Descriptions.pdf' which was downloaded from the Wildlife Computers web site (https://wildlifecomputers.com/wp-content/uploads/manuals/Spreadsheet-File-Descriptions.pdf) on December 15 2018. The programming specifications and tag details are provided in either a *.htm or *.rpt file. These are the files created at the time the tag was programmed. The included '00_kotzeb04_get_data.Rmd' is an R Markdown file that describes the process for downloading and renaming files from the Wildlife Computers Data Portal. The '00_kotzeb04_get_data.html' file is created when this R Markdown file is run
