Abstract: VLF surface-impedance measurements were made along four traverses on the Antarctic ice sheet in the vicinity of Casey base. Computer modelling of the surface-impedance data allowed ice-depth predictions to be made; predictions which are almost independent of ice temperature for ice depths less than 800 m. Results agree with ice-radar and other ice-depth data. Surface-impedance anomalies were observed close to moraines and crevasses in the ice sheet. The technique is fast and the instrumentation sufficiently portable for single-person operation.
