Description :
Accumulation rate measurements on the East Antarctic plateau are challenging due to both spatial and temporal variability. The AA. present a suite of accumulation rate measurements collected over several seasons at Taylor Dome. They compare net accumulation results from direct burial rate measurements and β-activity firn cores along a 35 km traverse. They map the depth of shallow radar layering to interpolate and extrapolate these point-location measurements and show that considerable variations occur over kilometer scales resulting from subtle surface topography.
