A nonprofit group called Project Nautilus will attempt to break the Guinness World Record for the longest open-water scuba dive this coming December.
The group will be attempting to keep a diver submerged on scuba for 100 hours. Additionally, the organization will be fundraising for the Make-a-Wish Foundation with a goal of raising US$1 million.
Project Nautilus will be attempting to double the current record of 50 hours, with a four-day, four-hour dive. During that time, the diver will be doing everything from eating, sleeping and cleaning up the surrounding reef. (No word yet on where or how said diver will, ahem, relieve him/herself.)
The dive is scheduled to take place in December 2015 off of Coki Beach on the island of St. Thomas in the U.S. Virgin Islands.
The group is looking for volunteers to be safety or standby divers.
