Hydromagnetic and VLF wave studies at the South Pole.

A brief description is presented of some recent analyses of ULF (D.C. to ~0.1 Hz) and VLF (~1 kHz) magnetic field investigations made at the South Pole. This set of data is particularly interesting in that it presents evidence for closed magnetic field lines at this very high latitude station. This report has been prepared for the annual review issue of the U.S. Antarctic Journal.
