Unified Interior Regions

Alaska

The Alaska Region represents a resource-rich, dynamic landscape shaped by volcanos, earthquakes, major rivers, and glaciers. Here, we conduct research to inform management of Alaska’s extensive natural resources, inform national Arctic energy policy, and provide scientific information to help others understand, respond to, and mitigate impacts from natural hazards.

Are the USGS Benchmark Glaciers spatially representative? Using geodetic constraints to develop a regional glacier mass balance record- Shad O’Neel

This project will integrate observations collected over a 50-year interval to provide deep insight into long-term patterns of glacier change in Alaska. Results will contribute to a broad range of disciplines from sea level change to fish biology. Work with an enthusiastic, dynamic group to understand the forcing behind the rapid change in the complex Alaska mountain glacier region.

Aufeis accumulations in stream bottoms in arctic and subarctic environments as a possible indicator of geologic structure: Chapter F in Recent U.S. Geological Survey studies in the Tintina Gold Province, Alaska, United States, and Yukon, Canada--results of a 5-year project

Thick accumulations of ice, called “aufeis,” form during winter along stream and river valleys in arctic and subarctic regions. In high-gradient alpine streams, aufeis forms mostly as a result of ground-water discharge into the stream channel. The ice occludes this discharge, perturbing the steady-state condition, and causing an incremental...
