NASA | IceBridge Flies High over Both Poles

The video discusses two campaigns surveying polar ice in the Arctic and Antarctic. Both missions use laser altimeters and photographic mappers on smaller aircraft. The campaigns aim to provide annual snapshots of ice conditions, measuring changes in snow and ice levels. Icebridge uses a G5 aircraft for the Antarctic and a Falcon 20 for the Arctic, with a focus on efficiency and precision. The Antarctic campaign includes the DMS photographic system and the high-altitude laser altimeter, Elvis, to monitor ice sheet changes and their impact on sea levels.

What is the purpose of the airborne topographic Mapper (ATM) in the ice campaigns?

What information does the laser altimeter called Elvis provide during the Antarctic campaign?
