SEALAB's Ocean Colony Dream Ends in Tragedy and a Quiet Fade

SEALAB in the 1960s tested whether humans could live underwater to enable ocean colonization. After early successes (SEALAB I–II) and extended stays, SEALAB III ended tragically with Berry Cannon’s death from likely carbon-dioxide asphyxiation, leading the Navy to end saturation-diving experiments by 1970. Offshore diving and robotic work persisted, while the underwater-colonization dream faded; Aquarius Reef Base remains a functioning undersea lab, and much of SEALAB’s hardware lives on only as museum relics.

First Private Subsea Habitat Goes Live, Enabling Real-Time Ocean Research From the Seafloor

DEEP’s Vanguard subsea habitat, located 17 meters underwater off the Florida Keys, will host up to four crew for near-real-time ocean science, with surface air, power, and satellite comms provided via an umbilical. The vessel uses a staged decompression after entry and features a moon pool for access to the seafloor, enabling longer, deeper research than traditional dives. NASA-trained aquanaut Dawn Kernagis is among the scientists involved, and the project aims to scale into broader subsea habitation through the Sentinel program by 2027, with potential applications in science, defense, and tourism.
