The Ocean Tracking Network (OTN) is a global aquatic research, data management & partnership platform headquartered at Dalhousie University in Halifax, Nova Scotia, Canada.

What does a whale sound look like? 🌊🎧 This spectrogram reveals a textbook fin whale song recorded by a Slocum glider deployed off the Scotian Shelf with JASCO Applied Sciences. The mission also detected sei, humpback & pilot whales, plus dolphins.

Our team had a great time at the H2O Conference in Halifax, connecting with ocean innovators, researchers, students, and industry partners. We also welcomed visitors into our glider shop during COVE's Demo Day to showcase how our Slocum and Wave Gliders support ocean research. 🌊 🐋

Proud to have joined the 2026 IAGLR–SCAS conference in Winnipeg 🌊 OTN shared research on Atlantic salmon & Ji’kaw (striped bass), hosted an R workshop on acoustic telemetry, and connected with partners across Canada. Thanks to all who stopped by!

🦇 Bat Glider!? A Wave Glider is now collecting data from both the ocean & sky. In a 1st-of-its-kind collaboration w/ ECCC, we've mounted an ultrasonic bat recorder on a Wave Glider to study offshore bat migration. Recently deployed, the Bat Glider will collect data from above and below the waves!

Last month, Iago Gradin from our telemetry ops team attended the All-Atlantic Ocean Research and Innovation Alliance forum in Brazil. He presented on OTN and joined a panel on ocean tech insights. A great opportunity to connect and share ocean science across the Atlantic 🌊

OTN is proud to support research in the Banc-des-Américains MPA (Gulf of St. Lawrence, off Gaspé), where telemetry tracks Atlantic wolffish and lobster. Using 50 OTN + 47 DFO acoustic receivers and diver tagging, researchers are revealing movements & habitat use to inform MPA monitoring 🪸 📸 DFO/MPO

The 2026 spring bloom mission is underway! 🌊 One of our Slocum gliders was deployed in February to monitor the NW Atlantic phytoplankton bloom. Working with Fisheries and Oceans Canada, we’re maintaining continuous glider coverage to capture this short but critical event. 📸: Melany Belzile, DFO/BIO
