Stratigraphic And Hydrology Of A Subpolar Ice Field, King George Island

A GPR survey was carried out to study the ice structure and hydrology at the main dome of the King George Island ice<br>field, Antarctica. The transmitted wavelets bandwidth was centered at 50MHz. Data show the presence of free water in<br>snow and in ice fractures. The water signature was inferred from the wavelet phase. A nearby borehole allowed the<br>calibration of the GPR sections in terms of composition and of resolving power of ice layers. Broadside perpendicular<br>and parallel antenna data collection schemes allowed for the identification of crevasses in the area.
