When the Boknis Eck Observatory – an environmental monitoring station on the floor of the Baltic Sea off the coast of Germany – stopped sending data on 21 August, scientists thought there was a problem with the data transmission.
But when they sent divers down to check, the whole 740-kilogram (1,630-pound) car-sized kit and kaboodle was just… gone. Completely vanished. All that remained was the cable.
“The devices were gone, the divers could not find them anymore,” said marine biogeochemist Hermann Bange of the GEOMAR Helmholtz Centre for Ocean Research in Kiel.
