A life support system for an undersea habitat which derives oxygen and potable water directly from the sea, without connection to shore or supply ships. Dissolved gases including oxygen and nitrogen, are stripped from sea water by passing a stream thereof in counter-current with rising steam derived from sea water heated in the boiler of a rectification tower. Oxygen is then separated from the other desorbed gases and conveyed to the habitat. The exhaust gas from the habitat is passed through a carbon dioxide absorber before being recirculated in the habitat. The carbon dioxide from the absorber and the residue of desorbed gases from the stripper, including nitrogen, are reabsorbed in the sea water, which is ultimately cooled and returned to the ocean.
