Interviews with USGS Alaska Science Center Scientists
These videos provide an overview of four of the USGS Ecosystems research programs at the Alaska Science Center: polar bear and shorebird research, the state-of-the-art molecular ecology lab, and the quantitative and statistical team. These programs provide timely science information for our partners.
The Aleutian Cradle of Tsunamis
THE ALEUTIAN CRADLE OF TSUNAMIS (Click here to read EOS Feature: Seismic Sources in the Aleutian Cradle of Tsunamis) New research on the Aleutian Islands has offered better insights into past great Alaska earthquakes and the dangerous, often far-travelling tsunamis they send across the Pacific. Large & Frequent Aleutian Earthquakes: Between 1938 and 1965, nearly…
Q&A: USGS and 2024 the Anchorage Bike to Work Day
For the May 17, 2024, Anchorage Bike to Work Day, the USGS Alaska Science Center will again host a station along the Lanie Fleischer Chester Creek Trail where people can learn about the USGS streamgage on the creek and about the common birds of Chanshtnu. Chester Creek or Chanshtnu, which means ‘grass creek’ in the Dena’ina language, runs for about 20 miles from the Chugach mountains in the eastern part of Anchorage to the Knik Arm of Cook Inlet.
USGS Arctic Research
The USGS and its partners are addressing issues in a rapidly changing Arctic
How Elodea Affects Juvenile Salmon Growth
The U.S. Geological Survey, U.S. National Park Service, and U.S. Forest Service are collaborating to understand the impacts of Elodea, an invasive aquatic plant species to Arctic and Subarctic ecosystems. Elodea is already established in multiple waterbodies in Alaska. Research on Elodea will help prioritize management efforts for this aquatic plant invader.
Why are Arctic Rivers Turning Orange?
Permafrost thaw may be contributing to discoloration of Arctic rivers by exposing iron-bearing minerals that were previously frozen and are now subject to weathering and hydrologic transport. One consequence of these altered iron-cycling processes is the abrupt change in color (orange) of stream and river reaches, reflecting a dramatic shift in water quality.
Strait Science Lecture Series
These video talks, hosted by UAF Northwest Campus and Alaska Sea Grant, provide an overview of USGS Ecosystems research programs at the Alaska Science Center. These talks are designed to share information relevant to the community members of the Bering Strait Region.
