Roseway Basin, Canada, September 2025
Study objectives
A Teledyne Webb Research Slocum G3s glider equipped with a passive acoustic monitoring system (DMON/LFDCS) was deployed in Roseway Basin for a 3-4 week mission in early September, 2025. The goal of this mission is to acoustically monitor for North Atlantic right whales and other large whale species in the Roseway Basin critical habitat. A second Slocum G3s glider equipped with an Ocean Observer acoustic system was deployed at the same time, and will continue monitoring until the end of October.
