The neutrino and the whale

Nature News : Giorgio Riccobene , a particle physicist at the Southern Laboratories of the Italian National Institute for Nuclear Physics (INFN) in Catania, was hoping to show that hydrophones could be used to detect subatomic particles called neutrinos that had come from deep space. Giovanni Pavan, a marine biologist from the University of Pavia in Northern Italy, was there to help Riccobene deal with background noise in the recordings.
But what Riccobene and Pavan discovered as they analyzed data from a series of hydrophones placed 28 kilometers off shore was the sound clicks of sperm whales, more whales in fact than biologists believed to exist in the area (see also powerpoint presentation 7.9 Mb ).
