Waterfowl Research

Scientists at the USGS Alaska Science Center have conducted research on waterfowl species (ducks, geese, and swans) in Alaska since the 1970s. Because Alaska is an international crossroads of migratory bird flyways, with millions of birds from Asia and North America breeding in Alaska each summer, USGS research has also taken place in adjacent countries (Russia, Japan, Canada, Mexico) and in...

Shorebird Research

With its vast size and geographic position at the northern end of several migration pathways, Alaska is a critically important site for the world’s shorebirds. Thirty-seven shorebird species regularly breed in Alaska. Most of these species conduct epically long migrations to take advantage of Alaska’s abundant food resources and breeding habitat, making Alaska a global resource for shorebirds...

Alaska Streamflow Statistics

The USGS conducts various studies of streamflow statistics for data collected at streamflow-gaging stations.

Arctic – Boreal Catchment Studies

Catchment hydrology focuses on the movement of water and solutes from landscapes to waterbodies. Our research addresses questions such as: Where is the stream water coming from? How long did it take to get here? What solutes, nutrients, and/or contaminants did the water pick up along the way? Because streams and lakes gather water and solutes, we can learn about the entire watershed by...

Hot springs (Alaska) caused by geothermal activity underground.

Hot springs can occur in many parts of the world. The water is hot not due to climate, but rather due to geothermal activity underground, such as volcanic activity or active hydrothermal heating from hot material in the ground. Hot springs result from water heated by underground geothermal activity finding its way to the land surface.
