Large Underwater Observatory Disappears Without a Trace, Baffling Scientists

A large monitoring station used to gather important scientific data in the Baltic Sea has mysteriously vanished.

The underwater observatory, which had been on the seafloor since December 2016, is managed by the GEOMAR Helmholtz Center for Ocean Research Kiel and the Helmholtz Center Geesthacht (HZG). On August 21 at 8:15 p.m. local time, transmissions from the €300,000 ($330,000) station came to a sudden halt. Divers were dispatched to the site, only to find—much to their astonishment—that the entire structure was gone, save for a shredded transmission cable, according to a GEOMAR statement.

The observatory was in a restricted area off the northern coast of Germany. Boats, including fishing vessels, are not allowed into the area, the BBC reported. That somebody, or a group of individuals, removed the observatory remains the most plausible explanation. Other factors, such as a massive storm, heavy currents, or even marine animals, were ruled out as potential causes owing to the weight of the instrument. Who or what removed the science station, and why, is a complete mystery. German police were alerted to the incident and are now investigating, according to GEOMAR.

The Boknis Eck Observatory is—or at least was—located at the outlet of Eckernförde Bay, which is north of Kiel, Germany and south of the Danish border. It was 1.8 kilometers (1.1 miles) off shore, planted at a depth of 22 meters (72 feet), reported the BBC.

The station collected data about water temperature, nutrients, salinity, the speed of water flow, and concentrations of chlorophyll and methane. This data is used to evaluate the health of the ecosystem in and around the southwestern Baltic Sea. By monitoring these changes, scientists can be alerted to potential problems and take the required countermeasures. Scientists have been collecting data in the bay since the 1950s. The observatory is also used in the COSYNA network (Coastal Observing System for Northern and Arctic Seas) of the HZG.

“[At] first we thought of a transmission error,” Hermann Bange, project coordinator for the Boknis Eck Observatory, said in the GEOMAR statement. This prompted a diving mission to the site, revealing the disappearance. “The devices were gone, the divers could not find them anymore,” he said. “When the divers reached the bottom of the sea last week at the observatory’s location, they found only the torn off land cable. It was completely shredded.”

The missing observatory consists of two racks, one weighing 250 kilograms (550 pounds) and the other 100 kilograms (220 pounds) each. The racks include a frame holding the power supply (along with a heavy cable connecting the station to the coast) and a frame to hold the sensors. Both racks were “removed with great force from their position,” according to the GEOMAR statement.

Bange described the data collected by the observatory as “downright priceless.” GEOMAR and HZA conducted their own search for the missing station, but with no luck. The scientists are now pleading for the public’s help, asking anyone who knows anything about the incident to come forward.

What interests me is that the cable was shredded, not cut. If it were thieves who knew of the equipment, I would have thought they'd have brought insulated bolt cutters to cut the wires. I half wonder if something ate the equipment.

Probably got snagged and dropped accidently. They prob didnt even know what they were doing.

Did you read the article, it has been down there and stationary since 2016, it wasn't moving around nor being lifted for any reason...

I did not click the link but did read the post...

I just thought if a ship would have dropped anchor and snagged it, then dropped it somewhere along their route without realizing it... a large ship might not even notice that it was dragging sonething... if there were weather or surge that caused it and its anchor to lift/drift.

Possibly but it's in a restricted area...

Could it have been pirates?
