Man made underwater air pockets

351 views

In NASA’s Aquarius research facility, there are 2 waystations called Pinnacle and Gazebo, where divers can refill their oxygen tanks as well as catch a breather because they’re air pockets. Could anyone explain how these air pockets are created right in the middle of a lot of water, with no cave like formations or anything? If you search online the waystations, literally look like a mini gazebo/tent that is open from underneath where water passes, however if you stand underneath it, till your torso there’s an air pocket. It’s really weird to look at, seems almost magical and that’s why I wanna know how it works.

It works similar to how a diving bell works. As air is light it naturally wants to go up and is caught up under the tent like structure to stop it escaping. The water cannot enter the air pocket because the pressure of the air is pushing down on it, keeping it out.
