Deep Water Emergence in the Milford Sound of Fiordland National Park (recorded underwater)

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.​ Hosted on Acast.
