Vessel Strikes on Whales Are Increasing With Warming. Can Ships Slow Down?

"Rising ocean temperatures and marine heat waves are pushing whales closer to busy shipping lanes. Flexible speed reduction areas could help prevent ship collisions, scientists say."

"Last March, a California giant perished. The 49-foot humpback nicknamed Fran washed up on a beach in the coastal city of Half Moon Bay. Fran had visited these waters for the entirety of her 17-year life, easily recognized by Californians due to the distinctive markings and shape of her tail.

This massive marine mammal provided crucial data to help scientists understand the intricacies of humpback feeding and breeding behavior—information crucial to the long-term survival of this enigmatic species.

A later necropsy revealed that the beached whale had a fractured vertebrae, severe chest bruising and her skull was dislocated from her spine, all injuries consistent with a ship collision. This whale’s suspected death is not the first of its kind—not by a long shot.

Shipping, cruise and fishing vessels fatally strike an estimated 20,000 whales around the world annually. In the United States, 80 endangered whales become “ocean roadkill” each year off the West Coast, and more than a third of all Atlantic right whale deaths along northeastern coastlines can be attributed to ship collisions."
