Tracking Data for Caribou (Rangifer tarandus granti) in Alaska Available here are tracking data of Caribou, a terrestrial mammal that ranges between the Alaska and Canada. These data were collected from animals marked in interior and northern Alaska to understand seasonal movement patterns and the effects of fire regime on the movements. USGS Alaska Science Center scientists collect data from wildlife tracking devices to: determine locations of animals throughout their annual cycles, understand patterns of habitat use, quantify time spent on various behaviors, and identify geographic areas repeatedly used by wildlife that may indicate sites of importance to species and populations. Tracking data from other wildlife species can be found at: https://doi.org/10.5066/P9VYSWEH.

The walrus distribution and utilization estimates are based on location data from satellite-linked radio-tracked walruses in the Chukchi Sea (2008-2011). Compared to previous years this period was marked by earlier and more extensive sea ice retreat (June - September) and delayed sea ice freeze-up (October - November). This allowed walruses to arrive earlier, occupy slightly more northern areas, and stay later in the Chukchi Sea than previously. Data are combined for all four years and...
