Ships in southeastern Atlantic and mid-Atlantic U.S. waters must slow down to protect endangered right whales starting this week.

A landmark regulation going into effect on Dec. 9 will require ships 65 feet or longer to travel at 10 knots or less in certain areas where right whales gather. These new speed restrictions will take effect in waters off New England beginning in January 2009 when whales begin gathering in this area as part of their annual migration. The goal is to reduce the chances ships will collide with whales, injuring or killing them.

With only 300 to 400 in existence, North Atlantic right whales are among the most endangered whales in the world. Their slow movements and time spent at the surface and near the coast make right whales highly vulnerable to being struck by ships, especially since shipping lanes into East Coast ports cut across their migration routes.

The 10-knot speed restriction will extend out to 20 nautical miles around major mid-Atlantic ports. According to NOAA researchers, about 83 percent of right whale sightings in the mid-Atlantic region occur within 20 nautical miles of shore. The speed restriction also applies in waters off New England and the southeastern U.S., where whales gather seasonally.

The speed restrictions apply in the following approximate locations at the following times; they are based on times whales are known to be in these areas:

  • Southeastern U.S. from St. Augustine, Fla. to Brunswick, Ga. from Nov. 15 to April 15
  • Mid-Atlantic U.S. areas from Rhode Island to Georgia from Nov. 1 to April 30
  • Cape Cod Bay from Jan. 1 to May 15
  • Off Race Point at northern end of Cape Cod from March 1 to April 30
  • Great South Channel of New England from April 1 to July 31

NOAA also will call for temporary voluntary speed limits in other areas or times when a group of three or more right whales is confirmed. Scientists will assess whether the speed restrictions are effective before the rule expires in 2013.

The rule is part of NOAA's broader effort to help the right whale population recover by protecting their habitat and reducing chances of ships colliding with right whales and of right whales entangling in fishing gear. Existing protective actions include surveying whale habitat by aircraft, mandatory ship reporting systems that provide advisories and information on right whale locations to mariners, shifting shipping lanes into Boston, recommending shipping routes into other coastal areas to prevent collisions, and regulations to prevent entanglement in fishing gear.

NOAA understands and predicts changes in the Earth's environment, from the depths of the ocean to the surface of the sun, and conserves and manages our coastal and marine resources.
