Professor Marv Lilley is about to return from an expedition to the 73°N on the Mid-Atlantic Ridge led by Professor Rolf Pedersen from University of Bergen. They have successfully located, mapped and sampled the northernmost hydrothermal vent field. The UW Press release:
Scientists break record by finding northernmost hydrothermal vent field: "Inside the Arctic Circle, scientists have found black smoker vents farther north than anyone has ever seen before. Dissolved sulfide minerals that solidify when vent water hits the icy cold of the deep sea have, over the years, accumulated around the vents in what is one of the most massive hydrothermal sulfide deposits ever found on the seafloor."
