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

Michael Cameron, Josh London, Kathy Frost, Alex Whiting & Peter Boveng
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...
