Q&A: USGS and the 2025 Anchorage Bike to Work Day
For the May 16, 2025, 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...
Eelgrass
Eelgrass is the predominant aquatic plant within embayments of southwestern Alaska and provides an important habitat for birds, fish, and invertebrates. The USGS has conducted extensive research on the status, trends, and use of eelgrass by migratory birds in southwestern Alaska primarily at the Izembek National Wildlife Refuge.
High Priority Species for Avian Influenza in Alaska
In early 2006, an Alaska Interagency Avian Influenza Working Group was formed to develop a ranking matrix for selecting priority species to be sampled within Alaska. Most wild bird species with populations that utilize areas of both Alaska and Asia were identified and considered in the ranking exercise. Based on scoring criteria, 28 target species were chosen for sampling. Alaska is a...
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 recently, very little was known about sea ducks in Alaska.
Natural Resources Preservation Program
This is a nation-wide collaborative program, supported by the USGS Ecosystems Mission Area, through which USGS and National Park Service staff address priority research needs identified by the National Park Service. On this page, we highlight research taking place in Alaska as part of this program.
Q&A: Marine Ecosystems Research at the USGS Alaska Science Center
The USGS Alaska Science Center is a leader and collaborator in marine ecosystems research on topics ranging from ocean bottom-dwelling invertebrates and small pelagic forage fish (food for Pacific walrus, sea otters, and marine birds) to polar bears (an apex predator in the Arctic). Here, we highlight current research by the USGS Alaska Science Center that focuses on marine ecosystems of Alaska.
