Scientists are in the process of creating an effective global network of watching the oceans in motion. The Ocean Tracking Network will be based on electronic tags implanted into creatures such as salmon, tuna, sharks, sturgeon, penguins or polar bears to register their movements via satellite or acoustic receivers on the floors of the oceans.

Ron O’Dor, a biologist at Dalhousie University in Canada said, “Today we know less about our marine life—how these animals live, where they go – than we know about the back side of the moon.” This new technology will open the path to smarter fisheries management, to better sea life conservation measures, and to the potential of abundant and sustainable stocks of commercial fish. It will also provide scientists with a massive increase in observations of rapidly shifting marine conditions.
