Cold Regions Lake and Landscape Research

Submitted by Anonymous (not verified) on

The Cold Regions Lake and Landscape Research at the Alaska Science Center studies the Arctic and Subarctic landscape. The primary objective is to understand landscape change in the recent (50 years) and distant (20,000 years) past using a combination of techniques that include remote sensing, GIS, field surveys, laboratory analyses, and model development. Comparing historical aerial photography with more contemporary high-resolution commercial satellite imagery shows changes to the abundance and surface area of lakes in two regions that provide important fish and wildlife habitat as well as sources of water for winter oil and gas exploration.  These studies allow land managers to make better resource management decisions.
