SUMMARY:Searching for UHE Cosmic Neutrinos with the Radio Cerenkov Tec
 hnique\, NPAC (Nuclear/Particle/Astro/Cosmo) Forum\, Amy Connolly\, Oh
 io State University
DESCRIPTION:There are strong motivations for a detectable flux of ultr
 a-high energy (UHE) cosmic neutrinos above 10$^{17-18}$~eV both from c
 osmic ray interactions with cosmic microwave background photons and di
 rectly from UHE astrophysics sources. The radio Cerenkov technique is 
 the most promising technique for instrumenting a detection volume larg
 e enough to sustain a long-term program measuring the low expected flu
 xes at the highest energies.  The ANtarctic Impulse Transient Antenna 
 (ANITA) is a balloon-borne antenna array that searches for radio impul
 ses from neutrino interactions from 37 km above the Antarctic ice shee
 t.  Its third flight under NASA's long-duration balloon program is pla
 nned for the end of 2014.  <br><br>
\nI will present the world's best 
 limits above 10^{19} eV from ANITA\, and plans for both ANITA 3 and th
 e future balloon project EVA.<br><br>
\nThe Askaryan Radio Array (ARA)
  is an antenna array being deployed at 200 meter depth near the South 
 Pole.  I will present the results of ARA's first search for UHE neutri
 nos using a prototype Testbed station in shallow ice.  The first stati
 ons of the proposed 100 km^2 area array have been deployed and neutrin
 o searches with these stations is underway.    I will also address the
  implications of current and future UHE neutrino measurements for part
 icle physics and astrophysics.<br><br>
