Abstract

Deep-sea volcanism on the Gakkel Ridge The latest deep submergence technologies have been used to perform the first high-definition photographic survey of the ultra-slow spreading Gakkel Ridge in the Arctic Basin, focusing on an area that is believed to have experienced a major eruption event in 1999. The images show that the axial valley at 4,000 m water depth is blanketed by an extensive set of pyroclastic deposits, raising important questions regarding the accumulation and discharge of magmatic volatiles on such ridges and demonstrating that large-scale pyroclastic activity is possible along even the deepest portions of the global mid-ocean ridge volcanic system.
