Marine animals hold promise for extending ocean monitoring
"An international team of researchers led by the University of Exeter suggests that a wide variety of marine species could be used for monitoring the world's oceans. Using electronic tags, scientists could exploit the natural behavior of sharks, penguins, turtles, seals and other species to fill gaps in our knowledge of the seas.
With three-quarters of the Earth's surface covered with water, having a comprehensive understanding of the oceans is very important in dealing with everything from fishing quotas to climate change. The problem is that the oceans are much bigger than most people realize and many parts aren't easily, if at all, accessible."
