Man made underwater air pockets

359 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.

They pump air into it. The gazebo is basically just an upside-down bowl. The air stays there because it has no where else to go.
