Project Summary |
Activity Area |
Secondary Activity Area |
| Airborne Studies of Ice Sheet Mass Balance | Krabill,
W. |
NASA | Take a “snapshot” of large areas of Greenland's glaciers, which have shown some dramatic changes in recent years. The measurements obtained during the aircraft flights will help scientists better understand glacial changes caused by global climate change. scrapbook | ||

C. |
NSF* |
Use an integrated observing system that will provide year-round measurements of volume, liquid freshwater and ice fluxes across Davis Strait. Fluxes through the Strait represent the net integrated Canadian Archipelago through flow, modified by terrestrial inputs and oceanic processes during its southward transit through Baffin Bay.
