About OTN
The Ocean Tracking Network is an ocean research and technology development platform headquartered at Dalhousie University in Halifax, Nova Scotia.
OTN promotes the discovery, conservation and sustainable use of aquatic animals through a global acoustic infrastructure and oceanographic monitoring equipment. This state of the art technology provides insight on the movement, distributions, and survival of marine and aquatic animals that is essential for sustainable fisheries and strong fishing communities.

Tags and receivers
Tags (top) — acoustic transmitters are surgically implanted or externally attached to aquatic animals. Tags transmit a uniquely coded signal that is picked up by bottom-moored receivers stations.
Receivers (below) — Receivers detect coded signals, “pings,” from tags. Some receivers also collect environmental data, which helps researchers better understand movements, habitat use, and survival.
Ocean monitoring vessels
Gliders
Wave Glider — Measures meteorological and near-surface ocean conditions, including wave height.
Slocum Glider — Measures ocean physics, chemistry and biology at high resolution.
