Available here are tracking data of Caribou, an ungulate that ranges between the Alaska Peninsula, up through interior Alaska and the Arctic Coastal Plain, and over to the Yukon Territory. These data were collected from animals living in three different herds including the Fortymile herd, Nelchina herd, and Denali herd.

Alaska Science Center Ecosystems data releases are grouped by topic: Terrestrial Ecosystems, Aquatic Ecosystems, Wildlife Health and Genetics, Environmental Health and eDNA, Habitat and Landscape Change, and Ecosystem Analytics.

Available here are tracking data of Polar Bear. Research focuses on the two polar bear subpopulation’s whose range includes Alaska: the Southern Beaufort Sea subpopulation that ranges between the North Slope of Alaska and western Canada and the Chukchi Sea or Alaska-Chukotka subpopulation that ranges between the northwest coast of Alaska and eastern Russia.

Climate changes and interacting disturbances such as wildfires, insect and disease outbreaks, and erosion and flooding can perturb and reorganize ecosystems.

The Arctic is warming at higher rates than much of the rest of the world. For Alaska, this results in changes in hydrology and ecosystems – permafrost is thawing, changing landscapes and releasing nutrients to soils and streams.

Catchment hydrology focuses on the movement of water and solutes from landscapes to waterbodies. Our research addresses questions such as: Where is the stream water coming from? How long did it take to get here? What solutes, nutrients, and/or contaminants did the water pick up along the way? Because streams and lakes gather water and solutes, we can learn about the entire watershed by studying...
