Alaska Science Center

The mission of the Alaska Science Center is to provide objective and timely data, information, and research findings about the earth and its flora and fauna to Federal, State, and local resource managers and the public to support sound decisions regarding natural resources, natural hazards, and ecosystems in Alaska and circumpolar regions. We have offices in Anchorage, Juneau, and Fairbanks.

A model of the spatiotemporal dynamics of soil carbon following coastal wetland loss applied to a Louisiana salt marsh in the Mississippi River Deltaic Plain

The potential for carbon sequestration in coastal wetlands is high due to protection of carbon (C) in flooded soils. However, excessive flooding can result in the conversion of the vegetated wetland to open water. This transition results in the loss of wetland habitat in addition to the potential loss of soil carbon. Thus, in areas experiencing rapid wetland submergence, such as the Mississippi Ri

Evaluating the efficacy of aerial infrared surveys to detect artificial polar bear dens

The need to balance economic development with impacts to Arctic wildlife has been a prominent subject since petroleum exploration began on the North Slope of Alaska, USA, in the late 1950s. The North Slope region includes polar bears (Ursus maritimus) of the southern Beaufort Sea subpopulation, which has experienced a long-term decline in abundance. Pregnant polar bears dig dens in snow drifts dur

Late Paleoproterozoic to early Mesoproterozoic deposition of quartz arenites across southern Laurentia

Supermature siliciclastic sequences were deposited between 1.64 Ga and 1.59 Ga over a broad swath of southern Laurentia in the Archean, Penokean, Yavapai, and Mazatzal Provinces. These siliciclastic sequences are notable for their extreme mineralogical and chemical maturity, being devoid of detrital feldspar and ferromagnesian minerals, containing the clay mineral kaolinite (or its metamorphic equ

Tracking Data for Long-tailed Ducks (Clangula hyemalis)

Available here are tracking data of long-tailed duck, a species of seaduck that breeds throughout the circumpolar Arctic and spends the winter in coastal areas of northern and mid latitudes. These data were collected to determine range-wide migratory routes, migratory timing, and stopover habitats of this species.

Tracking Data for Pacific Walrus (Odobenus rosmarus divergens)

Available here are tracking data of Pacific walrus, a marine mammal that ranges between the Alaska Peninsula, up through the Bering and Chukchi seas, and over to Russia. These data were collected from animals marked in the northern Bering and Chuckchi sea to understand seasonal movement patterns, use of coastal haulouts in northwestern Alaska, and determine estimates of abundance in autumn.

Use and History of the North Pacific Pelagic Seabird Database (NPPSD)

Data on the distribution and abundance of seabirds at sea have been used for many decades to assist in understanding the marine ecology of seabirds away from their breeding colonies, measure population status and trends, assess the impact of human activities on ocean habitats and fish stocks, and to identify critical marine habitats for seabirds.
