The ocean is one of the five biomes within Biosphere 2. The others are: rainforest, savannah, desert, and marsh. This view down onto the ocean shows a rowboat pulled onto the beach.
The ocean is a million gallons of saltwater, complete with fish and coral reef. The beach in the foreground was a favorite picnic spot for the Biospherians. The marsh is in the background.
The rainforest is at the top of the cliff.
