Ice ages have waxed and waned for millions of years. So have volcanic eruptions, maybe, on roughly the same scale. Could the two processes be related? A team of Lamont-Doherty scientists (together with colleagues from Harvard, Penn State and Oxford University) traveled to the Juan de Fuca Ridge in the North East Pacific in the fall of 2014 aboard the R/V Atlantis to find out if under-sea volcanism varied on ice-age like cycles. We collected deep-sea sediments holding geochemical tracers of past hydrothermal eruptions and sub-surface lava deposits and mapped the seafloor with seismic techniques under the Volcanoes, Ocean Ice and Carbon Experiments (VOICE) project.
