Humpback whale 'Timmy' released in the North Sea after weeks stranded off Germany

The mammal’s health deteriorated as it became repeatedly stranded in shallow waters near the coastal city of Wismar, and unsuccessful efforts to coax it toward deeper seas were livestreamed across the globe.

The environment minister for Germany’s Mecklenburg-Western Pomerania state gave the green light for the attempt to save the whale, proposed by a private initiative, despite some warnings from the scientific community that it may be too much for the animal.

Jens Schwarck, a member of the private initiative who was on site, said the whale was released around 9 a.m. local time, according to the German news agency dpa. The agency reported that the whale was released 70 kilometers (about 45 miles) from the coast of Skagen, Denmark.

Drone footage showed a whale swimming and spouting water near the barge, though it was not immediately confirmed that the animal was indeed Timmy.

A debate emerged about whether to let the whale die in peace or try to assist its return to the Atlantic Ocean. Activists staged protests on the beach in Wismar calling for its liberation, while others have supported new ideas about how the whale could be transported.

Some scientists believe the whale had searched for shallow waters because it was weak and needed rest. The veterinarians of the private initiative, however, considered the animal fit for transport.

Before the release, a GPS transmitter was reportedly attached to track the whale’s future location, according to dpa.

It is not clear why the whale swam into the Baltic Sea, far from its natural habitat in the Atlantic Ocean. Some experts say the animal may have lost its way while swimming after a shoal of herring or during migration.

Since then, the mammal became repeatedly stranded in shallow waters. It was in clear distress, breathing irregularly and often barely moving for days.

Timmy also suffered from a bad skin condition, related to the Baltic Sea’s low salt content, and rescuers applied kilos (pounds) of zinc ointment.

Local media produced dayslong livestreams to feed the outsized public attention over the fate of the whale. Online newspapers blasted push alerts with the smallest developments about Timmy’s health.
