Pegasus Airfield Repair and Protection: Laboratory Trials of White Ice Paint to Improve the Energy Reflectance Properties of the Glacial-Ice Runway Surface
The U.S. Antarctic Program at the National Science Foundation (NSF) Division of Polar (PLR) is currently in the planning stages of a logistics support project to reestablish an all-season wheeled airfield to service McMurdo Station. In the interim, NSF-PLR is also investigating remedial and triage-t...
