MONTREAL - A new marine monitoring system that can detect undersea earthquakes, whale songs, ship noise and tidal activity could help improve environmental regulations, according to a recently-published study.

The monitoring network, developed by scientists from McGill University, Natural Resources Canada, the Université du Québec à Montréal and Dalhousie University, has been deployed in Quebec’s Bas-Saint-Laurent region along the south shore of the lower St. Lawrence River.
