Tracking Data for Kittlitz's Murrelet (Brachyramphus brevirostris)
Available here are tracking data for the Kittlitz’s murrelet, a rare seabird species that nests solitarily on the ground in barren, often alpine areas near the North Pacific and Bering Sea.
Pacific Marine Heatwave
The USGS conducts research on marine wildlife, habitats, and ecosystem processes to provide science to inform our partners as they make decisions relative to species status, resource use, and human activities. These studies examine impacts of severe heatwaves on marine ecosystems of the North Pacific.
Collaborative Science for Priority Information Needs
One of the primary missions of the USGS is to address the science needs of Department of Interior bureaus, particularly those that manage natural resources and lands. This mission is fulfilled through the research and other activities of USGS scientists but also specifically through three USGS nationally-funded programs listed below.
Bird Species Checklists from USGS Alaska Science Center Field Camps
Scientists from the USGS Alaska Science Center regularly work in remote field camps, often for days or weeks at a time. Though not the primary research focus of these camps, many researchers maintain daily checklists of all bird species encountered during field work. These checklists can provide documentation of the presence, distribution, timing of arrival and departure, and breeding...
Molecular Ecology Laboratory
The main objectives of the USGS ASC molecular ecology research program are to 1) Identify and fill gaps in our knowledge about species and population diagnosis, biodiversity, and health of wildlife and their habitats to inform decision making by management agencies and 2) Provide state-of-the-art molecular science applications and protocols for USGS, Department of Interior, and other partners...
Ecosystems Analytics
Ecosystems Analytics is a group of quantitative biologists and research statisticians with a diverse range of expertise and experience (summarized below). We collaborate with internal and external partners to answer challenging ecological questions that are a high priority of the U.S. Geological Survey Alaska Science Center, sister agencies within the Department of the Interior (DOI), and...
Swan Research
USGS research on swans in Alaska has focused on pathogens, contaminants, and demographic rates in each of the different breeding areas of Alaska. The vastly different migration patterns of swans in Alaska means that there are multiple factors on the wintering grounds and during migration that may influence population size and trends.
Beavers Impacting Tundra Ecosystems (BITE)
The range expansion of the North American beaver (Castor canadensis) has implications for water quality, aquatic ecosystems, and fisheries in Arctic streams.
North Pacific Pelagic Seabird Database
The North Pacific Pelagic Seabird Database (NPPSD) includes more than 460,000 survey transects that were designed and conducted by numerous partners primarily to census seabirds at sea.
USGS Alaska Science Center Wildlife Tracking Data Collection
Understanding the short- and long-distance movements of wildlife is critical for a wide variety of ecological research questions and management decisions. Since the mid-1980s, the USGS Alaska Science Center has used information from telemetry devices on wildlife species to determine locations of animals throughout their annual cycles, understand patterns of habitat use, quantify time spent on...
Changing Arctic Ecosystems
Arctic regions of Alaska are important for cultural and economic sustainability and host a wide variety of wildlife species, many of which are of conservation and management interest to the U.S. Department of the Interior. The USGS and collaborators provide information about Arctic ecosystems that are used by Arctic residents, management agencies, and industry.
Loon Research
Scientists at the USGS Alaska Science Center have conducted research on Alaska’s three loon species since the late 1970s. Loons rely on freshwater lakes for nesting habitat and fish and invertebrates inhabiting lakes and marine ecosystems for food. All three loon species in Alaska occur within the National Petroleum Reserve-Alaska (NPR-A) on Alaska’s northern coast. Research by the USGS is...
