  We present a compilation of recent results, submitted to the 2003
International Cosmic Ray Conference (Tsukuba, Japan). These include: a) Revised
Monte Carlo estimates of the radiofrequency signals produced by electromagnetic
showers in ice, b) an updated search for ultra-high energy (UHE) neutrinos
based on detection of radio-wavelength Cherenkov radiation; such radiation
results from neutrino-induced electromagnetic showers in cold Polar ice, and c)
An in situ measurement of the index of refraction through the South Polar firn.
