Recorded 28 feet below the surface of the water, join Mandela in the Discovery Center's Underwater Observatory for an interview with Daniel Crook & Andrea Ferris. Daniel & Andrea are nature guides in The Milford Sound of Fiordland National Park on New Zealand's South Island's West Coast. The Discovery Center is a floating building which gives visitors the chance to view extremely rare species usually found between 50-5,000 feet deep in the ocean.Overlaying the sea water in the fiord is a layer of fresh water, the result of high annual rainfall in Fiordland. This combined with the narrow shape of the fiord causes a phenomenon known as deep water emergence where light is not allowed to penetrate past the fresh water. This creates a similar environment to the deep ocean at a much shallower depth, allowing visitors the chance to see deep sea species close up.Unlike an aquarium, the fish are free to come and go; it is the people who are contained. This provides a unique opportunity to observe real life situations deep below the surface of the fiord, quite different from the artificial environment of an aquarium.​
