Five voyages to the most exotic and dramatic underwater locations in the world.
The Kelp Forests of Calif orn ia. In this third film bubblehelmeted divers
Martha Holmes and Mike deGruy dive beyond the pounding
Californian surf to a submarine forest of breathtaking beauty - and predatory blue sharks. The underwater trees are a type of seaweed, giant kelp. Through sunlit glades the divers find harbour seals, bat rays, clouds of colourful fish and sea otters.
Just beyond the kelp, the angel shark proves to be no angel, while further out in deep water, a dive with blue sharks calls for heavy protection. Producer Robin Hellier
