AN INVENTORY OF ANTARCTIC SUBGLACIAL LAKES

An extensive analogue database of 60 MHz radio-echo sounding records o f Antarctica (covering 50% of the ice sheet) is held at the Scott Pola r Research Institute, University of Cambridge. This database was analy sed in order to determine the presence and location of Antarctic sub-g lacial lakes. In total, 77 sub-glacial lake-type records were identifi ed, 13 more than detected in previous studies. An inventory of these s ub-glacial lakes includes geographical coordinates, minimum length and overlying ice thickness for each lake. Information concerning the loc ation of these lakes indicates that the majority (similar to 70%) are found in the proximity of ice divides at Dome C and Ridge B within Eas t Antarctica.
