Shediac Valley, Gulf of St. Lawrence, Canada, July 2022


Study objectives

A Teledyne Webb Research Slocum G3s glider equipped with passive acoustic listening device (DMON/LFDCS) was deployed in the Laurentian Channel region of the Gulf of St. Lawrence (GoSL) for a multi-month mission with an extended lithium primary battery pack. The purpose of this mission is to monitor for North Atlantic right whales and study their regional habitat use.
