I just attended a very informative and entertaining seminar. It was on this proposed mobile neutrino detector under the project called "Hanohano", where "Hano" here means "Hawaiian Anti-Neutrino Observatory". Of course, it is led by the University of Hawaii.
It's a fascinating project of moving a large chamber full of scintillators on a barge to the middle of the ocean (or any place that has a deep ocean floor), and then sinking the detector chamber to the bottom of the ocean. You can read for yourself from the link why there is a significant advantage to having something like that. Not only is something like this useful in terms of studying the fundamental properties of neutrino oscillation, but it has also many other practical applications in terms of studying the structure and properties of our earth via the detection of geo-neutrinos, and even military monitoring of rogue nuclear detectors and detonation of nuclear weapons.
Always something new to learn every single day....
