A long-standing mystery among marine biologists is why otherwise healthy whales, dolphins, and porpoises — collectively known as cetaceans — end up getting stranded along coastal areas worldwide. Could severe solar storms, which affect Earth’s magnetic fields, be confusing their internal compasses and causing them to lose their way?
A long-standing mystery among marine biologists is why otherwise healthy whales, dolphins, and porpoises — collectively known as cetaceans — end up getting stranded along coastal areas worldwide. Could severe solar storms, which affect Earth’s magnetic fields, be confusing their internal compasses and causing them to lose their way?
Although some have postulated this and other theories, no one has ever initiated a thorough study to determine whether a relationship exists — until now. NASA heliophysicist Antti Pulkkinen, who works at the agency’s Goddard Space Flight Center in Greenbelt, Maryland, has teamed with the federal Bureau of Ocean Energy Management, or BOEM, and the International Fund for Animal Welfare, or IFAW, to determine whether a link exists.
Strandings occur around the world, involving as few as three to as many as several hundred animals per event. Although a global phenomenon, such strandings tend to happen more often in New Zealand, Australia, and Cape Cod, Massachusetts, said project collaborator Katie Moore, the director of IFAW’s global Animal Rescue Program. Headquartered in Yarmouth Port, Massachusetts, IFAW operates in 40 countries, rescuing animals and promoting conservation to secure a safe habitat for wildlife.
