The North Atlantic Right Whale (NARW) is one of the most endangered whale species, with only about 366 remaining in the world. In 2017, 12 individuals died in the Gulf of  St. Lawrence. The high mortality rate is mainly due to the collision with vessels and the entanglement with fishing gears.

Protection measures, which include vessel speed reduction, fishing closure, and investing in new acoustic technologies, were then put in place by the Department of Fisheries and Oceans (DFO) to prevent the recurrence of such events.

Passive Acoustic Monitoring (PAM) is an observation method where hydrophones are deployed in the ocean to capture sounds from the surrounding environment. Marine mammal acoustic experts periodically, 2 to 4 times a year, collect the recordings from the hydrophones. PAM has become a crucial tool in observing endangered whales providing continuous round-the-clock information over the season.
