MarineLab Undersea

Laboratory Museum

From 1985 - 2018, the MarineLab Undersea Laboratory was located in a lagoon at the Marine Resources Development Foundation’s campus in Key Largo. Hundreds of aquanauts, ranging from high school students to physicists and medical researchers, visited or even stayed overnight in the Undersea Lab.

The MarineLab Undersea Laboratory was raised from the lagoon in 2018 and restored to its 1985 condition. Visitors can climb up inside the habitat and experience what it was like for aquanauts staying underwater, without having to get wet!

The MarineLab Undersea Laboratory Museum may be visited Tuesday through Sunday from 8 am to 3 pm at MarineLab Undersea Park.
