It will detect coherent radio Cherenkov emissions from the particle showers produced by neutrinos with energies above about 10^17 eV.
ARIANNA will be built on the Ross Ice Shelf just off the coast of Antarctica, where it will eventually cover about 900 km^2 in surface area.
ARIANNA detector stations will each contain 4-8 antennas which search for brief pulses of 50 MHz to 1 GHz radio emission from neutrino interactions.
An initial search for neutrinos was made; none were found, and an upper limit was generated.
