DEEP Vanguard ushers in a new era of underwater living

Key Points:

• DEEP’s Vanguard station, deployed in June 2023 in the Florida Keys, is the first new underwater human habitat in US waters in 40 years, designed to house four aquanauts for missions lasting five to seven days with modern eco-friendly systems.
• The station aims to support coral reef restoration and monitoring efforts in the Florida Keys National Marine Sanctuary, using saturation diving to maximize underwater research time and improve data quality.
• Florida has committed nearly $1 million to support research teams using Vanguard, with future missions planned to include marine scientists, military personnel, educators, and artists.
• Unlike past government-funded underwater habitats, Vanguard is privately owned by Canadian Robert MacGregor, with DEEP planning significant expansion including larger habitats and a global network of subsea stations.
• The resurgence of underwater habitats parallels the sustained human presence in space, with hopes to advance marine biology through long-term underwater living, although funding and collaboration remain critical challenges.
