The hole truth: scientists solve mystery of ‘pogo-stick’ seabed tunnels

When scientists discovered holes poked into the floor of the Bering Sea, they were baffled. Now they think they have found the culprit

During an expedition in the cold waters of the Bering Sea, between Russia and Alaska, last summer, a team of scientists spotted neat lines of holes poked into the seafloor. But they did not know who – or what – had created them.

Scientists on the German research vessel Sonne set about hunting for clues. They sifted through several hundred images captured by a camera towed above the seafloor.
