Alaskan National Park Glaciers: Status and Trends, First Progress Report

This is the first progress for a multi-year study of glaciers in Alaskan national parks. The project will be completed in December 2013. Here we present results from mapping of all glacier extents in Glacier Bay National Park and Preserve (NP&P) and Denali NP&P, from measurements of surface elevation changes on select glaciers in Glacier Bay NP&P, and from focus glacier research on Brady, Margerie, and Muir Glaciers in Glacier Bay NP&P.
