Biology instructor Jessica Fain (USA) spent 73 days 2 hours 34 minutes living 7.31 m (24 ft) underwater in Jules’ Undersea Lodge, a steel-and-glass facility anchored at a depth of 9.14 m (30 ft) just off the coast of Key Largo, Florida, USA. Fain achieved her record in a joint effort with biology professor Bruce Cantrell: the two scientists entered the underwater habitat on 3 October 2014 at 12:08 EST and left it on 15 December 2014 at 13:42 EST.
During their stay, a joint venture between the Marine Resources Development Foundation (MRDF) and Roane State Community College (RSCC) in Harriman, Tennessee, they hosted a series of weekly videos streamed on YouTube as part of an educational project about marine conservation and biology called Classroom Under the Sea.
The precedent was set by a all-female team led by Sylvia Earle living under the sea in Tektite II in Great Lameshur Bay, St. John's Virgin Islands from 6 to 20 July 1970. The Mission 6-50 team members included Renate True, Alina Szmant, Margaret Ann Lucas and Ann Hartline.
