The towed seafloor sampler Camper grabbed these volcanic rocks from the
seafloor of the Arctic Ocean for study by WHOI geologist Susan Humphris
and colleagues. Now that the 40-day expedition to the Gakkel Ridge is
over, the researchers have months of heavy lifting to do back in the
laboratory...cataloging and analyzing their samples from a part of the
ocean floor that has scarely been studied.
