Giant Ocean Tank
Night and Day in
the Giant Ocean Tank
When the sun sets and it gets dark at Central Wharf, the same effect is replicated above the Giant Ocean Tank.
And at 8 a.m. each day, the GOT’s LED lighting transitions back to daylight, during which time there is a beautiful blue hue that last for a few minutes.
The lighting system, which was part of extensive renovation work on the GOT in 2013, is designed to simulate natural lighting transitions to help maintain the rhythm of a Caribbean coral reef and ensure the well-being of the animals in the GOT. Each day at 8 a.m., the night lighting begins to transition to a sunrise as the lighting gradually changes to a blue hue and then to typical daytime lighting. During the day, the lights can be turned on and off and rotated around the tank to imitate cloud cover.
From night to sunrise to day
The 2013 renovation of the GOT was extensive and included some new artificial corals, larger viewing windows, an expanded dive room for the divers, a handicap-accessible ramp, and the replacement of the upper concrete perimeter with viewing glass to allow for better views into the 200,000-gallon tank. A new communication system was also added allowing a diver in the GOT to communicate with visitors gathered at the top. Every day at 2:30 p.m., a diver wears a full facemask that allows the underwater diver to hear and respond to visitors’ questions that are relayed by the educator on the platform. The diver also is equipped with a small camera, and video is fed live to the screens atop the GOT.
