    Although scientists used to believe that there was no volcanic activity on Gakkel Ridge in the Arctic Ocean, recent expeditions uncovered evidence of hydrothermal vents and fragmented pyroclastic volcanic deposits that cover the axial valley of the ridge. Has anyone heard about that?

    Its been known for a number of years now. Its not surprising given the surrounding boundaries

    What are the findings and why don't we hear anything from the experts that this may be a cause for the melting of Artic glaciers and ice sheets...and be a source of heat causing the "global warming" controversy? I've heard or read NOTHING about this in the press! Vents from these moving Artic tectonic plates may be warming the waters and the ice directly above them!

    Because the ridge is far below the surface of the arctic ice and has been continuously active with no effect on the ice, the ocean currents pull the heated water away from the ridge and disperse it before any significant amount reaches the underside of the ice. So no the volcanic activity of the ridge is NOT effecting ice melt.
