Neutrino Sciences 2007

Deep Ocean Anti-Neutrino Observatory Workshop

Honolulu, Hawaii

March 23-25, 2007

The Center for Neutrino Sciences at the University of Hawaii at Manoa announces Neutrino Sciences 2007 DOANOW on March 23-25, 2007. This international meeting brings together particle physicists, earth scientists, and engineers with interests in a deep ocean, antineutrino observatory. Conference sessions explore studies of neutrino mass and mixing, nucleon decay, supernova and solar neutrinos, the composition and energetics of earth's interior, nuclear monitoring, and engineering/technical issues.

The deep ocean antineutrino observatory presents significant science potential when designed to allow relocation from one site to another. At a deep ocean location near Hawaii the observatory measures antineutrinos from uranium and thorium in earth's mantle and makes a sensitive search for antineutrinos from a hypothetical natural fission reactor in earth's core. A deployment offshore a nuclear reactor complex measures neutrino mixing parameters with the possibility of resolving neutrino mass hierarchy.

Workshop Summary

Hanohano information


All sessions of DOANOW will be held in the Pacific Room in Jefferson Hall at the East-West Center on the University of Hawaii at Manoa campus. It is just a short walk from here to the Physics Department in Watanabe Hall or the School of Ocean and Earth Sciences and Technology (SOEST).

Scientific Organizing Committee

Steve Dye (U. Hawaii), John Learned (U. Hawaii), John Mahoney (U. Hawaii), William McDonough (U. Maryland), Sandip Pakvasa (U. Hawaii), Joe Van Ryzin (Makai Ocean Engineering)


A $100 registration fee to be paid in full by cash will be charged to all participants to help cover workshop expenses. There will be no exceptions. The fee includes refreshments during the breaks, reception on Friday evening, and party Saturday night.
