Continental Shelf Station Two, Underwater research station in Port Sudan, Sudan.
Continental Shelf Station Two was a starfish-shaped underwater research facility located near Port Sudan in the Red Sea. The complex featured multiple interconnected modules positioned at different depths, providing living areas, laboratory space, and a hangar for submersible vehicles.
The station was built in the early 1960s as an experimental center for deep-water research in the region. It represented part of a broader international effort to develop methods for ocean exploration and extended underwater habitation.
The project demonstrated how people could actually live and work underwater for extended periods, challenging previous assumptions about human limits. This vision of underwater habitation captured the public imagination as a glimpse into future exploration.
The site is underwater and can only be explored by divers, not by surface visitors, so you will need appropriate diving certification and experience. Visiting requires hiring a local dive guide who knows the location well and can handle the specific conditions of the Red Sea.
The station included a pressurized deep chamber set at 30 meters below the surface where scientists could study how human bodies respond to extreme pressure conditions. This deep component was essential for understanding adaptation to the ocean's crushing force.
