Scientists now think that they know why whales are failing

Scientists now believe that sonars used by ships cause such stress in animals that they interrupt their natural diving pattern – giving themselves "in turns".

"Elbows" is a painful condition in which nitrogen bubbles accumulate in the blood and afflict human divers if they resurface too quickly.

Autopsies of stranded whales showed that they too could suffer meanders.

Researchers now believe that the medium-frequency active sonar (MFAS) used to detect submarines can "frighten" whales, especially beaked whales.

Lead author Yara Bernaldo de Quiros, a researcher at the University of Las Palmas de Gran Canaria in Spain, said: "In the presence of sonar, they are stressed and swim vigorously to get away from the sound source, which modify their dive pattern.

"In other words, the stress response takes precedence over the diving response, which forces the animals to accumulate nitrogen.

"It's like a shot of adrenaline."
