Secrets of the North Sea (2013)

Die Nordsee: Unser Meer is a feature-length nature documentary directed by Klaus Müller, which looks as the fauna and flora that resides in the water and along the coastlines of the North Sea in northern Europe; from gray seals swimming in the waters off Heligoland in Germany or basking on the chalk cliffs of Dover in England, to large squid in the Dutch Oosterschelde, the film uses helicopters and underwater cameras to observe these lovely creatures from all possible perspectives.
