The USGS Benchmark Glacier mass balance program strives to quantify glacier mass changes, climate parameters and streamflow at four glacierized basins in North America. The glaciers are distributed in different climate regimes to better define glacier response to changes in climate forcing. Data from two glaciers located in climatically distinct basins form the basis of this project in Alaska: Gulkana Glacier, a continental glacier located in the Alaska Range, and Wolverine Glacier, a maritime glacier located in the Kenai Mountains. Outside of Alaska, the project includes Washington state's South Cascade Glacier, which is located in a mid-latitude maritime environment, and Montana's Sperry Glacier, located in the mid-latitude continental or transitional climate regime, within Glacier National Park. This research is aimed at refining knowledge of how glacier-climate interactions drive socio-economic problems including sea level change, water supply and ecosystem linkages. Over the 1966–present study interval, study glaciers have retreated and lost mass, primarily as a result of summer warming.
