A moon pool is a feature of marine drilling platforms, drillships and diving support vessels, some marine research and underwater exploration or research vessels, and underwater habitats, in which it is also known as a wet porch. It is an opening in the floor or base of the hull, platform, or chamber giving access to the water below, allowing technicians or researchers to lower tools and instruments into the sea. It provides shelter and protection so that even if the ship is in high seas or surrounded by ice, researchers can work in comfort rather than on a deck exposed to the elements. A moon pool also allows divers or small submersible craft to enter or leave the water easily and in a more protected environment.
Moon pools can be used in chambers below sea level, especially for the use of scuba divers, and their design requires more complex consideration of air and water pressure acting on the moon pool surface.

Famous quotes containing the words moon and/or pool:
“The moon was waiting for her chill effect.
I looked at nine: the swarm was turned to rock
In every lifelike posture of the swarm,
Transfixed on mountain slopes almost erect.”
—Robert Frost (1874–1963)
“Just getting in the pool for seven straight hours is unbearable to me.... It’s grueling. There’s nothing physically pleasurable about it. If you’re doing a hard workout, you’re throwing up in the gutter. At night you cling to your pillow and just hope that your body revives before you have to go back and do it again.”
—Diana Nyad (b. 1949)
