While providing advice is the major component in our mandate, CEMAM scientists are also involved in fundamental, leading edge science. This research includes such activities as our participation in the international Trans-North Atlantic Sighting Surveys, of which the Canadian component provided the first estimates of abundance and distribution of many cetaceans, turtles and basking sharks along the Canada Atlantic coast. Also, we have been active in the development of a new framework for the management of seals, deployments of cameras on seals to study foraging behaviour; studying habitat use of blue whales and beluga using time-depth recorders and developing new data analyses approaches; documenting the increase in observations of killer whales in the Arctic, looking at movements of satellite equipped seals, and reactions of bowhead whales to seismic activity; studying killer whale predation on other cetaceans, completing the first ever Pacific-wide estimate of humpback whale abundance, or the ongoing changes in killer whale survival and its tight link to Chinook salmon stocks.
