The Ocean Tracking Network (OTN) began at Dalhousie University in 2008.

The TWS gliders are electrically powered and collect physical, biological and chemical information.

Additionally, OTN maintains a rental fleet of Innovasea Vemco acoustic receiver units for use by those in academia, government, non-profits and industry.

[4]The Natural Sciences and Engineering Research Council of Canada (NSERC) gave $10 million in network funding; and additional funding was received from the Social Sciences and Humanities Research Council (SSHRC) and international partnerships.

[5] OTN and the Prince William Sound Science Center formed a partnership in 2013, to support the science center’s Pacific Ocean Shelf Tracking (POST) project.
