While focused initially in Canada, OTN is deploying Canadian-made acoustic receivers and oceanographic monitoring equipment in all of the world’s five oceans. This global receiver infrastructure comprehensively examines the local-to-global movements of tagged marine animals such as sharks, sturgeon, eels, and tuna, as well as other marine species including squid, sea turtles, and marine mammals. OTN’s underlying concept is to share costs, resources, expertise and data with global partners to enable the creation of a global acoustic telemetry network.
