The NUNAtak Ice Thinning (NUNAIT) Calculator for Cosmonuclide Elevation Profiles
Cosmogenic nuclides are widely used to constrain the landscape history of glaciated areas. At nunataks in continental polar regions with extremely arid conditions, cosmogenic nuclides are often the only method available to date the ice thinning history of the glacier. However, the amount of cosmogen...
