Since 2008, rules requiring ships to slow down to avoid collisions with North Atlantic right whales have reduced fatalities of the criticall
Excerpt from this story from Smithsonian Magazine:
Even though whales take up a lot of space, they can be surprisingly stealthy in the water. Regina Asmutis-Silvia, executive director of Whale and Dolphin Conservation North America, knows firsthand how difficult it can be to spot one and avoid a collision.
When sheâs steering a research boat, Asmutis-Silvia looks for specific types of ripples at the surface or spouts of water from a blowhole to signal that a whale is nearby. But even so, the animals can be unpredictable.
âTheyâre not out here paying attention to you,â she says. âWhales that are looking for food and eating are very focused. Itâs probably the whale version of hangry!â
Recently, Asmutis-Silvia was moving her boat extra slowly near Woods Hole Oceanographic Institution in Massachusetts, having noticed signs of whales in the area. Suddenly, a North Atlantic right whale popped up just 30 feet ahead, off the boatâs bow. âThatâs not atypical whale behavior for right whales,â Asmutis-Silvia says. âThese animals do what they want.â
She had time to turn her vessel away from the mammal, because of her low speed, but many other cases donât end so harmlessly. Whale strikes have been on the rise in areas along the East Coast, likely due to the growth of global shipping in the past few decades. Worldwide, vessels fatally hit an estimated 20,000 whales each year. Recent examples of dead whales washing ashore on New York and Delaware beaches have brought the toll of vessel strikes into the public eye.
Since 2008, the National Oceanic and Atmospheric Administration (NOAA) has regulated ship speed in some areas along the East Coast to protect critically endangered North Atlantic right whales. Mother-calf pairs are often sighted within about 40 miles of the New England shoreline. Because whales move north to south along the coast and major shipping lanes span east to west, the animals and vessels are liable to collide. Research has shown that the best way to prevent collisions, aside from rerouting ships entirely, is to have ships slow down.
Now, NOAA, which enforces laws within 230 miles of the United Statesâ coast, is calling into question the necessity of this ship speed regulation. The agency has begun investigating whether technology to detect whales may be sufficient to prevent strikes.
While conservationists support developing detection technologies, they are concerned that a change to the current speed limit could lead to more injured whales on our beaches and higher risks to the endangered right whales. Weakening the existing protections would be âreally dangerous for the survival of the species,â says Brett Hartl, government affairs director for the nonprofit Center for Biological Diversity.
