Abstract
The ARIANNA project seeks to observe cosmogenic neutrinos with energy in excess of $10^{16}{eV}$ through the use of a grid of over 1000 independent radio detector stations. These stations search for the characteristic Askaryan radio pulses, from particle cascades generated in the ice by these neutrinos, with a bandwidth of $50 - 1000{MHz}$. Spaced a kilometer apart, this array would effectively survey approximately 750 cubic kilometers of Antarctic ice. Currently, the Hexagonal Radio Array (HRA) at the Moore's Bay site (Ross Ice Shelf) serves as a pilot for the ARIANNA concept. A neutrino signal analysis will be presented using data from two seasons of HRA operation. We will also discuss the projected sensitivity of the full ARIANNA array using real-world performance data from the HRA, and show that ARIANNA will be able to probe conservative models of the GZK neutrino flux.
