Effectiveness of mandatory vessel speed limits for protecting North Atlantic right whales
To reduce right whale Eubalaena glacialis deaths caused by ship collisions along the US East Coast, a rule was implemented on 8 December 2008 requiring all vessels ≥65 feet (19.8 m) to travel 10 knots (18.5 km h-1) or less in 10 seasonal management areas (SMAs). To evaluate the effectiveness of this...
