Three miles beneath the Arctic ice cap, just shy of the North Pole, lies an ancient underwater midocean ridge known as the Gakkel. It was one of the last areas on Earth yet to be explored, but intrepid geologist Rob Reves-Sohn of the Woods Hole Oceanographic Institution decided eight years ago that he wanted to change that. At the Gakkel, Earth's crust is spreading slowly apart, uncovering new volcanoes and deep hot springs rife with never-before-seen extreme microbes. Reves-Sohn knew the region would teach him and other scientists new lessons about how Earth's plates move and what lies beneath them—so he had to go there, and soon. ...
