Eruptions of strong gas plumes near the Bennett Island (Arctic, Russia, De Long Archipelago) observed during 1973-1986 were
studied on the base of complex field and laboratory works. The site of probable sources has been found as presented by submarine
cones of presumably basaltic outflows dated as a period from 1974 to 1983. Iron-manganese nodules picked up near the cones are
hydrothermal products. Rhythmic character of gas explosions is comparable with the change of the Earth rotation velocity and similar
to rhythm of volcanic process and the strength of eruptions is adequate to average strength of basalt cones production. The volcanic
hypothesis of the Bennett gas plumes origin, expressed before, is confirmed.
