Background:

Uncertain reports of submarine activity have been noted from a location beneath the Arctic icecap, along the Lomonosov Ridge extending between Greenland and Siberia. This site, at a reported depth of about 1500 m, lies only 192 km from the North Pole. Pumice deposits on the coast of Spitzbergen Island dated to the 2nd half of the 15th century and the 1st half of the 18th century were considered to apparently originate from this location (Hantke, 1962). During a four-day period in 1957, a scientific station on the Arctic pack ice reported sea quakes, rumbling and explosion noises, fracturing of icebergs, and a strong smell of hydrogen sulfide from one of the new fissures. Later work has shown, however, that the Lomonosov Ridge is a fault block consisting of a continental sliver separated from Eurasia during the propagation of the Mid-Atlantic Ridge into the Arctic Ocean (Vink et al., 1984; Jakobsson et al., 2003).
