One New and One Extended Vessel Speed Restriction Zone South & Southeast of Nantucket to Protect Right Whales Through March 18

NOAA Fisheries announces one new and one extended voluntary vessel speed restriction zone (Dynamic Management Area or DMA) south and southeast of Nantucket.

On March 3, 2020, the NOAA aerial survey team observed two separate aggregations of right whales, one 31 nautical miles south of Nantucket and the second 47 nautical miles southeast of Nantucket. 

The DMAs are in effect immediately, through March 18, 2020.  

These DMAs both cover areas in shipping lanes. Mariners are requested to route around both areas or transit through it at 10 knots or less.

Right Whales Are Migrating 

North Atlantic right whales are on the move along the Atlantic coast of the U.S. NOAA is cautioning boaters and fishermen to give these endangered whales plenty of room. We are also asking all fishermen to be vigilant when maneuvering to avoid accidental collisions with whales and remove unused gear from the ocean to help avoid entanglements. Commercial fishermen should use vertical lines with required markings, weak links, and breaking strengths. 

Right Whales in Trouble

North Atlantic right whales are protected under the U.S. Endangered Species Act and the Marine Mammal Protection Act. Scientists estimate there are only about 400 remaining, making them one of the rarest marine mammals in the world.

North Atlantic right whales are NOAA Fisheries' newest Species in the Spotlight. This initiative is a concerted, agency-wide effort to spotlight and save marine species that are among the most at risk of extinction in the near future. 

In August 2017, NOAA Fisheries declared the increase in right whale mortalities an “Unusual Mortality Event,” which helps the agency direct additional scientific and financial resources to investigating, understanding, and reducing the mortalities in partnership with the Marine Mammal Stranding Network, Canada’s Department of Fisheries and Oceans, and outside experts from the scientific research community.
