Sea temperature from August to September 2012 as recorded by OTN's Slocum electric glider deployed along the Halifax acoustic telemetry line. Data from OTN's fleet of autonomous gliders supports the ocean observing and modeling platform by surveying essential physical, chemical, biological and ecological processes and interactions.

Technicians from the University of Tasmania deploy acoustic receiver moorings in the Bass Strait, between Australia and Tasmania. The OTN Tasmania and OTN Perth Arrays are helping researchers monitor large-scale species movements and the role of the East Australian Current to improve the accuracy of the ocean observing model currently in place. Data from the projects can be found on the OTN Members' Portal

OTN employs two Teledyne Webb Slocum electric gliders on the Halifax Line (268 acoustic receiver and monitoring stations from Halifax to the edge of the Scotian Shelf). The gliders are providing oceanographic data that will be related directly to the activities of tagged animals that's north-south movements are tracked on the Halifax Line.
