Large numbers of cetaceans are dying from lethal collisions with vessels, even in protected areas. Now science may provide the means to protect them
that compared fatal strikes to strikes that, allegedly, didn’t kill the whale. The results showed that the probability of a whale dying of a strike is around 50% at 10 knots, compared to the near-certainty of death at double the speed.suggests that even if 95% of large ships in the Santa Barbara channel slowed to 10 knots, the reduction in whale mortality would be 30% at most.
Unwieldy, high-speed container ships, on the other hand, need much more warning time, so the cameras have to detect whales when they are further away. Because blows last only a few seconds, they are tricky to reliably detect at a distance. “Right now [the reliable detection range] is between two and three kilometres and actually we need it to go to about four,” says Zitterbart.
If everybody just thinks about Moon, so that if they see a [whale’s] blow, they slow down, that would be wonderfulSome pitfalls remain. For instance, OrcaAI’s algorithms mainly detect the whale’s tail, but Zitterbart says whales only show their tails when diving, which usually takes them out of danger.
