THE NEW STEINHART AQUARIUM
Project Description
The new Steinhart Aquarium will be one of the most biodiverse and interactive aquariums in the world. Home to an estimated 10,000 animals representing more than 600 separate species, it will offer guests an unprecedented view of underwater life and provide insight into the critical role that aquatic environments play in life on Earth.
Ties to the Past
The original Steinhart Aquarium opened in Golden Gate Park in 1923. It quickly became world famous for its novel exhibits and unusual animals, and was the model for many of the public aquariums that opened in the years that followed. Several components of the old Steinhart Aquarium will return when the new Aquarium opens back in the park in 2008, including the dramatic entrance columns, the vaulted ceiling, the sea horse railing, and the Swamp (alligator) exhibit.
New Exhibits
More than half of the public exhibit space in the new California Academy of Sciences will be devoted to Steinhart Aquarium. New technologies and advances in animal husbandry have made it possible for the Steinhart to create a suite of stunning new aquarium exhibits, including the world’s deepest living reef tank, a four-level rainforest display, and a unique, ever-changing Water Planet exhibit.
Living Coral Reef
• The coral reef tank, which will be the second largest living coral reef display in the world, will measure 12,000 square feet and hold 212,000 gallons of water.
• At a depth of 25 feet, the new coral reef display will be the deepest exhibit of live corals in the world. Visitors will be able to view the exhibit from the surface as well as from five underwater windows.
• The exhibit will house a broad range of aquatic life from the coral reefs and mangroves of the Philippines, one of the most diverse reef systems in the world. These animals will include delicate soft and hard corals, sharks, rays, and more than 4000 colorful reef fishes.
• All of the animals for the reef exhibits will be captive bred, or come from sustainable wild sources, highlighting the importance of in-country research and conservation programs.
• The special needs of the fish and corals will be met by a sophisticated life support system that will filter the entire tank volume about once an hour. 120 metal halide lamps will simulate natural sunlight.
• A glass “bridge†will allow for close observation of sharks and rays cruising just inches below the guests.
• A jet system will simulate ocean movements and stimulate the corals.
• The exhibit will incorporate in-tank cameras and video footage, interactive displays, and regular in-tank diver presentations. To support its dive programs, the new Steinhart will be recruiting over 100 volunteer divers to help maintain the large exhibits, feed the fish and interact with the public.
