Longest stay in an underwater habitat (Europe)

36 days | Lacustris Programme (Romania) — Aquanauts Liviu Miron & Constantin Mihai set the European record of 36 consecutive days in July 1994 while living aboard the L.S.-1 Underwater Laboratory in Lake Bicaz. The scientific programme, which focused on habitat operations, scuba diving, as well as human physiology and behaviour, was supervised by Dr. Ionel Miron of Alexandru Ioan Cuza University. Upon exiting the L.S.-1, Miron and Mihai were greeted by the Romanian Minister of Youth and Sports (Alexandru Mironov) and media representatives, including Jeffrey Gallant, who had earlier interviewed the aquanauts inside the habitat (watch video below). Launched in 1967, the L.S.-1 is the longest serving underwater habitat still in operation. It was installed on a rail-based mobile platform that was first used to carry lumber up a hillside after the Bistrița Valley was cleared of trees during the construction of the Izvorul Muntelui Dam in the 1950s. The L.S.-1 may thus be lowered or raised at the desired depth to conduct scientific research or to allow aquanauts to undergo decompression while still inside the habitat. Its original purpose was to study fish behaviour in aquaculture at a time when remote viewing with underwater cameras was still technically challenging, i.e. the aquanauts observed captive fish placed in cages in front of the habitat’s portholes.
