Laser mapping project shows effects of physical changes in Antarctica's Dry Valleys

The Canada Glacier in the McMurdo Dry Valleys. Researchers funded by the National Science Foundation (NSF) have publicly released high-resolution maps of Antarctica's McMurdo Dry Valleys, a globally unique polar desert.
The high-resolution maps cover 3,564 square kilometers of the McMurdo Dry Valleys and allow researchers to compare present-day conditions with lower-resolution LIDAR surveys conducted almost 13 years ago.
Scientists from Portland State University led the new research project, which mapped the area using ... More at
