Organization's Description:

OTN Ocean Glider Programme
@ Dalhousie University

The world's oceans are vast and ever changing. They are impossible to describe properly using research vessels only, although ships will always be needed to sample directly. Satellite technology has greatly improved our ability to obtain global coverage of some environmental variables such as sea-surface temperature, currents and the abundance of phytoplankton, but satellites cannot see into the ocean's interior. Underwater gliders can help to fill the gaps between satellite imagery and shipboard sampling.

As part of the work of the Ocean Tracking Network, Dalhousie University has purchased two Teledyne Webb Slocum electric gliders (OTN200 and OTN201) that are deployed along the Halifax Line, running from Chebucto Head to approximately 250 km offshore. Their mission is to provide oceanographic context for the animal tagging efforts of OTN. Ultimately, data from the gliders will provide foundations for models of ocean dynamics that will be related directly to the activities of tracked species.

The OTN gliders fly through the water in a saw-tooth pattern, carrying a suite of sensors to measure physical, chemical and biological characteristics of the ocean interior. They are relatively inexpensive to operate and can be deployed year round in all sea states. While at the surface, they communicate via satellite to transmit data and receive new instructions. Some data are presented on this site. OTN researchers can access data now by contacting When appropriate quality control procedures are implemented, results will be made available to the public.
