Frequency of whale and vessel collisions on the US eastern seaboard : ten years prior and two years post ship strike rule

"Protected species science programs are frequently asked to provide management advice based on imperfect data associated with occurrence rates of rare events such as strandings, road kills or other rarely detected mortalities. Ship strikes of large whales and right whales are such settings, and they are of particular interest because economically significant management actions have been enacted to hopefully reduce their occurrence"--Introduction. by Richard M.
