Eight critically endangered North Atlantic right whales have died this summer, several of them hit by ships.
In the last two years alone, 20 North Atlantic right whales have been found dead in Canadian waters. Of the 11 that could be studied, seven were found to have died as a result of vessel strikes.
That has prompted Canada's Department of Fisheries and Oceans to announce a new round of funding to develop better ways for ships to find whales and avoid hitting them.
One of those technologies is thermal infrared imaging.
