Britain's Secret Seas Part 3: The Power of the East

This time, the team set out to explore the waters off out eastern coastline, which are constantly pounded by the raw power of the waves.

These are the shallowest waters off our shores but over the centuries they have been some of our most productive, providing oil and gas as well as fish for our tables. But things are changing in the North Sea and the Secret Seas team discover a sea full of surprises.

On the Farne Islands they come face-to-face with England's largest colony of Grey Seals to find out what makes them such extraordinary divers and successful hunters. Grey Seals can dive for over 40 minutes on a single breath and the team find our just how they do it and how they are coping with the East coast's changing conditions far better than the Harbour Seal.

Elsewhere, Frank Pope looks at the newest form of energy in the North Sea, at a wind farm off the Norfolk coast and Tooni examines what effect the wind turbines are having on marine life.

Paul Rose also uncovers the intriguing history of light vessels across the sandbanks of the Thames Estuary and Tooni gets to the bottom of a bumper lobster harvest in the port of Bridlington.
