The Ocean Tracking Network tracks the enormous migrations of sea creatures including Lydia the Shark, now famous for her transatlantic odyssey over the past year
Dalhousie University’s Ocean Tracking Network (OTN) tags marine animals such as fish, sharks, seals and polar bears and tracks them using satellites and acoustic arrays. Placed across bodies of water, these devices create an acoustic wall that can detect the tagged animals as they pass through it. This allows OTN to record the movements of sea creatures in real time, study their survival and migration patterns, and observe their response to changing ocean climate. OTN also looks at the animals’ genetic markers, diet, physiology, breeding strategies and how deep they dive to get prey.
