Alaska Science Center
Home
The Alaska Science Center provides 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.
Spotlight on Science
Dr. Colleen Handel, 2019 Islieb Award recipient, has authored more than 80 scientific papers that chronicle her interdisciplinary research on the ecology of poorly studied shorebirds and landbirds throughout Alaska.

Study of Alaskan Landslide Could Improve Tsunami Modeling
A rare submarine landslide provides researchers with a reference point for modeling the biggest tsunamis. (EOS article)
New tsunami evidence along one of Earth’s largest faults, the Alaska-Aleutian megathrust
Recent geological studies of a key section of the Aleutian Island chain of Alaska suggest Aleutian tsunamis may occur more frequently than previously understood.
2018 Anchorage Earthquake
A magnitude 7.0 earthquake struck north of Anchorage, Alaska, on November 30, 2018, at 8:29 a.m. local time (17:29:28 UTC).

Geographic variation in the intensity of warming and phenological mismatch between Arctic shorebirds and invertebrates
Responses to climate change can vary across functional groups and trophic levels, leading to a temporal decoupling of trophic interactions or ‘phenological mismatches.’ Despite a growing number of single-species studies that identified phenological mismatches as a nearly universal consequence of climate change, we have a limited understanding of...

The influence of body size, condition, and age on recruitment of four Alaskan brown bear populations
Recruitment of brown bear (Ursus arctos) offspring into a population is the product of initial cub production and subsequent survival and is a critical component of overall population status and trend. We investigated the relationship between maternal body size, body condition, and age (as a surrogate for gained experience) and recruitment of...
Hilderbrand, Grant V.; Gustine, David; Joly, Kyle; Mangipane, Buck; Leacock, William; Cameron, Matthew; Sorum, Mathew; Mangipane, Lindsey; Erlenbach, Joy Effects of simple acid leaching of crushed and powdered geological materials on high-precision Pb isotope analyses
We present new results of simple acid leaching experiments on the Pb isotope composition of USGS standard reference material powders and on ocean island basalt whole rock splits and powders. Rock samples were leached with cold 6 N HCl in an ultrasonic bath, then on a hot plate, and washed with ultrapure H2O before sample digestion in HF‐...
