We report new limits on cosmic neutrino fluxes from the test flight of the
Antarctic Impulsive Transient Antenna (ANITA) experiment, which completed an
18.4 day flight of a prototype long-duration balloon (LDB) payload in early
2004. We search for impulsive events that could be associated with ultra-high
energy neutrino interactions in the ice, and derive limits that constrain
several models for ultra-high energy neutrino fluxes, including the
long-standing Z-burst model.
