Sant Ocean Hall

Smithsonian National Museum of Natural History

Dive In!

There’s not another Earth system that affects all of life as profoundly as the ocean. This 23,000-square-foot exhibition takes you from the shore and shallows all the way down to the ocean floor. On this fascinating dive, you’ll also travel through time, from the origins of the ocean 3.8 billion years ago to the challenges and exciting scientific opportunities the ocean presents today.

The Sant Ocean Hall contains more than 600 specimens, as well as life-sized models like Phoenix, a real North Atlantic right whale who scientists have been tracking since her birth in 1987.

The ocean is a global system, essential to all life.
