Using the Power of the Sun to Study Sharks

Thursday, 02 January 2014 | by Pat's Picks

Solar power has made its way underwater - as researchers are now using solar-powered tags to track and study sharks. The South Florida Sun Sentinel says the new tags replace battery-powered ones that would sometimes die before scientists could get all the information they needed. Because most sharks don’t swim near the surface, the tags collect data for six months using conventional batteries, then detach and float to the surface where they can get solar power so the data can be transmitted.
