New finds along Arctic mid-ocean ridge



A recent expedition to explore the 1,100-mile Gakkel Ridge beneath the Arctic ice cap has turned up 12 previously unknown volcanoes, hydrothermal vents with species that are potentially new to science, and other unexpected findings about the world's slowest-spreading and least volcanically active mid- ocean ridge.

Researchers aboard the U.S. Coast Guard Cutter Healy and the German icebreaker F.S. Polarstern made the findings during a July 31–October 3 cruise as part of the Arctic Mid-Ocean Ridge Expedition (AMORE), funded by the U.S. National Science Foundation. The researchers announced their results on November 28.
