The Leviathan Habitat is the undersea habitat designed specifically for the Atlantica Expeditions world record breaking 80 day mission scheduled to begin in 2009.  The Leviathan is designed for continuous habitation four aquanauts during the extended undersea mission.The Leviathan is designed to maximize functionality in a restricted space.  Its floor plan allows for two private aquanaut staterooms as well as a private bath, separate wet room with hot shower and a command and control room that doubles as the community space and entertainment module.The Leviathan features an air handling system with triple redundancy throughout: three air conditioners – dehumidifiers and three air circulators.  The habitat’s life support system consists of oxygen delivery via air from S3 mounted compressors, dual carbon dioxide scrubbing systems that are also each triply redundant.

The Leviathan’s energy is supplied by a surface support system (S3) that features triply redundant air compressors, four independent 3000 watt remotely operated generators and an contingency battery bank.  The S3 also consists of four wind generators and a bank of solar panels.

The Leviathan was designed with 21st century electronic throughout including exclusive use of very low energy and low heat producing LED lighting throughout the habitat.

The habitat’s communication system features state of the art 21st century digital communications including full cell telephone service, high speed internet, satellite telephone and video links.

The Leviathan is a fully functioning scientific laboratory featuring environmental monitoring and data collection as well as some wet lab capabilities.

The Leviathan will enable three aquanauts to live onboard for a record breaking 80 day non-stop mission as well as allowing for one or two additional aquanauts to join them for 24 to 72 hour missions.  Up to six aquanauts will be able to join the mission as two may occupy the adjoining New World’s Explorer at any time during the mission.

One of the prime purposes of the Leviathan design is to test systems and procedures for implementation in the much larger Challenger Station habitat scheduled to be launched in 2012 as the first permanent undersea colony off the Florida coast.
