Radar absorption due to impurities in Antarctic ice / Hugh Corr, John Christopher Moore, Keith W. Nicholls.

Title: Radar absorption due to impurities in Antarctic ice / Hugh Corr, John Christopher Moore, Keith W. Nicholls.
Author(s): Corr, Hugh.
Moore, John Christopher.
Nicholls, Keith W.
Date: 1993.
In: Geophysical Research Letters. (1993.), Vol. 20(11) (1993)
Abstract: Measurements of radar echo strength on Ronne and George VI ice shelves show differences in ice-column absorption that cannot be resolved by considering ice temperatures alone. Presents absorption model that resolves discrepancy by considering ice impurity concentration as well as ice temperature. Using this model, impurity levels in ice column at George VI site are deduced from radar strength measurements and found to be typical of levels measured in Antarctic ice at similar elevations and distances from sea. In particular, measurements suggest that concentrations of biogenically derived acids are much lower than unusually high levels found on east coast of Antarctic Peninsula.
