Concerns have been raised that the installation of the monopiles of the Vesterhav North wind farm offshore Denmark could cause a small pod of dolphins to leave the area. The dolphins have, however, neither left the area nor have they changed their behaviour, Vattenfall, the owner and developer of the wind farm, said.

In 2020, wildlife and underwater photographer Lars Mikkelsen discovered a pod of seven Common Bottlenose dolphins during a sailing trip in the canal between the North Sea and the Limfjord at the Danish coastal town of Thyborøn. Since then, Mikkelsen has been closely following the dolphins that are rare guests in the seas around Denmark.
