Reducing the risk of lethal encounters: vessels and right whales in the Bay of Fundy and on the Scotian Shelf
The North Atlantic right whale Eubalaena glacialis is endangered, in part, due to vessel-strike mortality. We use vessel traffic and right whale survey data (similar to 3 nautical miles [n miles], similar to 5.6 km resolution) for the Bay of Fundy and on the Scotian Shelf (northwest Atlantic) to det...
