From the clever folk who brought you the ECOCEAN Whale Shark Database:

The newest innovation in ‘citizen science’ is the sharkGrid. This web-based system borrows your computer’s spare processing capacity to match digitised whale shark spot patterns – allowing whale shark sightings from all over the world to be analysed and mapped. In short: the longer lunch break you take, the more you help whale shark science. Do it for the fish.

Proving the effectiveness of the ECOCEAN system, we had another match returned today of a South African whale shark, MZ-022. This four metre shark was first photographed at Sodwana Bay by Rob and Sam Bester of Whale Shark Watch in January 2007 and re-sighted in Tofo two months later by Chris Williams from Quest Underseas. Very cool!
