The military operations underway during the Russia-Ukraine war seems to be disrupting dolphins sonars, causing them to wash up dead.
, an environmental scientist at The Conflict and Environment Observatory, a charity based in the U.K, toldin October that the impacts of marine life during conflict are perhaps"the most difficult environmental damages to monitor during war."
"The most visible sign of damage is the washing up of cetaceans on the beaches around the Black Sea. Anecdotally numbers are higher than in previous years, suggesting a link with the conflict—most likely military sonar, where there is a relatively well-established link to behavioral change in cetaceans," Darbyshire said.
Dolphins have their own sonar for navigating the ocean. They use them to get around and seek out prey.Ewa Węgrzyn, an author of the Royal Society study at the University of Rzeszów, Poland, told"Previous research on the effect of military exercises on cetaceans showed that exposure to sonar signals led to a great energy deficit in whales. Energy loss over 40 percent is a lethal threat to cetaceans and it may result from only ten days of fasting," Węgrzyn said.
"It has been documented that sonar signals can disrupt cetacean behavior over distances of up to 90 nautical miles suggesting that the extended and large-scale military operations during the war may have left little undisturbed space for cetaceans in the Black Sea."
