This pilot project for the Antarctic Ross Ice-Shelf Antenna Neutrino Array (ARIANNA) consists of seven autonomous stations, called the Hexagonal Radio Array (HRA). Located on the surface of the Ross Ice Shelf in Antarctica, the HRA is designed to detect short-duration radio pulses generated by neutrino interactions in the ice, which reflect from the ice-water boundary at the bottom of the Ross Ice Shelf up to the stations on the surface. These measurements provide important insight regarding the locations of the most powerful particle accelerators in the universe, and they allow physicists to probe for novel physics beyond the standard model used in the field.

Field Season Overview

Four participants will deploy to McMurdo Station and travel by helicopter to the ARIANNA site at Moore’s Bay, where they will remove all data-acquisition electronic boxes and antenna towers and return them to McMurdo for retrograde. Two participants will continue to South Pole for ten days to completely remove and retrograde the two stations installed there.
