Based in France, the project has a specific objective to “enable [researchers and explorers] to live underwater for long periods of time,” says oceanographer Ariel Fuchs, executive director of the project. The oceanic research and exploration vessel took more than 12 years to plan. Construction is scheduled to begin this spring and, including integration of the initial scientific and communications equipment, is expected to cost $52 million and take 12 to 18 months.
