Unified Interior Regions

Alaska

The Alaska Region represents a resource-rich, dynamic landscape shaped by volcanos, earthquakes, major rivers, and glaciers. Here, we conduct research to inform management of Alaska’s extensive natural resources, inform national Arctic energy policy, and provide scientific information to help others understand, respond to, and mitigate impacts from natural hazards.

Dabbling and Diving Duck Research

Dabbling and diving ducks, such as mallards, pintails and scaup, are widespread species throughout North America.  Additionally, their migratory flyways pass through Asia and North America overlap in Alaska.  Population trends of these species are closely tracked through aerial surveys by management agencies.  Results from these and other surveys are then used to formulate management actions...

Sea Duck Research

USGS research on sea ducks is designed to anticipate and address priority information needs of management agencies.  Additionally, work is focused on individual species biology, migration and population status and trends because until just recently, very little was known about sea ducks in Alaska.

Wildlife Disease and Environmental Health in Alaska

Environmental health is defined by connections between the physical environment, ecological health, and human health. Current research within the U.S. Geological Survey (USGS) recognizes the importance of this integrated research philosophy, which includes study of disease and pollutants as they pertain to both wildlife and humans. Due to its key geographic location and significant wildlife...

Waterfowl Research

Scientists at the USGS Alaska Science Center have conducted research on waterfowl species (ducks, geese, and swans) in Alaska since the 1970s. Because Alaska is an international crossroads of migratory bird flyways, with millions of birds from Asia and North America breeding in Alaska each summer, USGS research has also taken place in adjacent countries (Russia, Japan, Canada, Mexico) and in...

Shorebird Research

With its vast size and geographic position at one end of numerous migration pathways, Alaska is a critically important site for the world’s shorebirds. Thirty-seven shorebird species regularly breed in Alaska. Most of these species conduct epically long migrations to take advantage of abundant food resources, making Alaska a global resource for shorebirds. Shorebird research at the USGS Alaska...
