Right whales are surface feeders that inhabit shallow areas close to shore, easily subjecting them to ship collisions, or “ship strikes.” Their niche also made them easy prey for commercial whalers, so currently there are exceedingly few right whales.

Cousins to the Bowhead whales, many of their calls are in the range of human hearing. Their moans and whelps suggest elephants, and the North Atlantic males produce a “gunshot” sound, so sound recordings could be mistaken for an elephant hunt.

That these animals are rare and threatened has brought a lot of focus to their preservation. This has facilitated the development of a fabulous monitoring program in the Stellwagen Bank National Marine Sanctuary designed, installed, and managed by Chris Clark’s lab (Cornell). Much is being learned about the whales, but also about shipping noise and masking models.
