US plans to slow ships down to protect critically endangered North Atlantic Right whales

August 2008. National Oceanic and Atmospheric Administration (NOAA) is in the final steps in the process of implementing new legislation designed to protect the critically endangered Northern right whale. The ship strike reduction rule aims to reduce the number of endangered North Atlantic right whales injured or killed by collisions with large ships.

10 knot speed limit
The final proposal contains six alternatives, including NOAA's preferred alternative that would require a vessel speed restriction of 10 knots or less in designated areas along the U.S. East Coast. The preferred alternative also includes a five year sunset provision to allow for further consideration of ongoing scientific research.

"NOAA is looking forward to taking a significant step in our efforts to protect right whales," said retired Navy Vice Admiral Conrad C. Lautenbacher, Jr., under secretary of commerce for oceans and atmosphere and NOAA administrator. "Our scientific analysis shows that a 10-knot speed limit in critical areas will significantly reduce the
threat to these endangered marine mammals."

Whale feeding grounds
The 10-knot speed limit would apply to right whale feeding grounds along the coast in the northeastern United States and to calving grounds near the southeastern United States, where the whales spend most of their time. In the mid-Atlantic area where right whales migrate, the 10-knot speed restrictions would extend out to 20 nautical miles around the major ports. NOAA's Fisheries Service researchers report that approximately 83 percent of right whale sightings in the mid-Atlantic were within 20 nautical miles of shore. The preferred alternative also would establish temporary voluntary speed limits in other areas when an aggregation of three or more right whales is confirmed.

Just 300 whales left alive

With about 300 in existence, North Atlantic right whales are among the most endangered whales in the world. Slow moving right whales are highly vulnerable to ship collisions, since their migration route crosses major East Coast shipping lanes. Along with existing measures to prevent entanglement of right whales in fishing gear, this would be the most comprehensive approach that NOAA has taken to regulate vessel operators in its effort to help right whales recover.

"The bottom line is that this critically endangered species needs our help," said Lautenbacher. "The preferred alternative is a balanced approach grounded in science that would significantly enhance our ability to protect right whales, but it would also take into account concerns about the safety of ship crews and the impact on an important segment of our economy."
