Sea Trek is five fantastic voyages to the most exotic and dramatic underwater locations in the world from the team responsible for Reefwatch and Supersense.
Specially developed 'bubble helmets' enable the presenters Martha Holmes and Mike DeGruy, both marine biologists, to talk under water when they come face-to-face with the magnificent, unusual and sometimes dangerous creatures of the deep.
The Hawaiian Islands
Episode 1x5; Nov 04, 1991
A whale shark looms out of the blue, dwarfing divers Martha Holmes and Mike de Gruy. It's a moment of high drama, a breathtaking encounter with the biggest fish in the ocean. But the intrepid pair came to these Pacific islands to track down another heavyweight - the humpback whale. Surrounded by the mysterious sound of singing whales, their hopes rise. Their persistence pays off when a 35-ton mother with a newborn baby lingers quite unconcerned in front of the camera. For the divers it's the highlight of an eventful trip, and a fitting finale to the Sea Trek voyages.
