摘要

The ARIANNA high energy neutrino detector is planned to be deployed on the surface of the Ross Ice Shelfto search for astrophysical neutrinos. Collisions with nuclei in the ice generate showers of particles that emit short pulsesof radiation, created by the Askaryan mechanism, in the frequency range of 100 MHz to 1 GHz. The ARIANNA site islocated about 65 miles from McMurdo Station, the main hub of US Antarctic operations, and is protected from ambientRF interference by a geologic formation known as Minna Bluff. In this work, we report preliminary results for thefrequency interval 90-180 MHz from site studies of the field attenuation length (averaged over depth), and reflection andpolarization properties of the saltwater-ice boundary.
