Doug Elsey (Canada) — Arctic IV Expedition led by Dr. Joe MacInnis in Resolute Bay, Nunavut (Canada), in May 1974. Elsey descended to 67 m (220 ft) breathing oxy-helium under the supervision of Dr. Phil Nuytten. Ice thickness was over 2 m (6.5 ft). The same expedition also resulted in the first saturation dive under polar ice.
