They always say its the U.S. Navy's fault for sonar throwing them off course. I don't know much about the subject but I think that is a bunch of BS.

I personally think it might have to do with rapid changes in water temperature and/or salinity, but again, I don't have any knowledge in this area. http://news.yahoo.com/news?tmpl=sto...p/20060430/ap_on_sc/tanzania_dolphin_deaths_6 Someone probably has a geographical database of beaching. They still have no idea how the whale managed to get up the Thames?
