Fine Beam RADARSAT-1 for Monitoring Pond Dynamics in the Alaskan Boreal Forest
Several recent scientific studies have used historic remotely-sensed imagery to document a substantial reduction in the number and size of ponds in many boreal regions of Alaska, including interior Alaska, the Kenai Peninsula, and the Seward Peninsula.
Uncertainties in Firn-Line Monitoring in Winter SAR Data
Since the launch of ERS-1 in 1991, SAR imagery has become widely used in glaciology. The ability to image a surface, regardless of cloud cover and solar illumination, is particularly useful in a discipline which is often concerned with polar regions or areas with a prevalence of cloud cover. Sea ice monitoring in North America and northern Europe has been one of the great success stories of spaceborne SAR. Now operational glacier monitoring using optical-thermal and SAR systems are underway.
