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...

Aleutian Islands Ecosystem Recovery Studies

The Aleutian archipelago is a 2,000 km long chain of volcanically-derived treeless islands stretching from Unimak Island in the east to the Commander Islands in the west.  These volcanic islands support a wide range of species including large numbers of seabirds and marine mammal species, some of which are threatened and endangered, leading to a high level of federal management concern.

Seabirds and Forage Fish Ecology

Alaska's coastal and offshore waters provide foraging habitat for an estimated 100 million birds comprising more than 90 different species; from loons and seaducks that nest inland, to petrels and puffins that breed on islands off shore. All these birds depend on the sea to provide a wide variety of food types— from clams, crabs and urchins nearshore— to krill, forage fish, and squid offshore...

Terrestrial Wildlife and Habitats

The USGS conducts research on trust Department of Interior migratory bird and mammal species and their habitats to inform agencies such as the US Fish and Wildlife Service, Bureau of Land Management and National Park Service in their natural resource management decisions.

The Alaska Science Center focuses its research on a wide range of species important to the Department.

Fish and Aquatic Ecology

Fish and aquatic habitats in Alaska support important commercial, sport, and subsistence fisheries and provide forage fish that support wildlife populations.  The USGS Alaska Science Center conducts interdisciplinary research to inform local, state, federal, and international policy makers regarding conservation of fish, aquatic species, and their habitats.  We work collaboratively with...

USGS Research Vessel Alaskan Gyre

The R/V Alaskan Gyre is a 50-foot fiberglass seiner that has been converted into a versatile research vessel to provide USGS scientists and collaborators with access to remote marine areas of Alaska and serve as a mobile laboratory.  The vessel was built by Ledford Marine of Marysville, Washington in 1989 and is named after the Alaskan Gyre, a series of wind driven currents that...

Beak Deformities in Landbirds

Over the past 20 years, Alaskans have witnessed a startling increase of beak deformities among Black-capped Chickadees and other species of resident birds. This disease, called avian keratin disorder (AKD), is characterized by debilitating beak overgrowth and other abnormalities of keratinized tissues. Affected birds have difficulty feeding and preening, and may suffer high rates of mortality...

Goose Research

Over the past two decades the USGS Alaska Science Center has had a central focus on addressing science questions related to geese in Alaska.  Science information is needed for these species because all have undergone changes in population size through time and are important resources for subsistence and sport hunters in the state and outside of Alaska where these birds spend the winter.  The...

Dabbling and Diving Duck Research

Dabbling and diving ducks (such as the northern pintail, mallard, teal, and scaup) are highly migratory and widespread species throughout North America.  For many species, their migratory flyways through Asia and North America overlap in Alaska and northeastern Russia.  Population trends of these species are closely tracked through aerial surveys by management agencies.  Results from these and...
