Results of the Arctic Mid-Ocean Ridge Expedition (AMORE 2001) - Seafloor Spreading at the Top of the World
The Arctic Mid-Ocean Ridge Expedition (AMORE 2001) returned in early October 2001 after an incredibly sucessful ten-week study of the Gakkel Ridge and its surrounding basins in the high Arctic. AMORE 2001 was an international effort involving two icebreakers: PFS Polarstern, from the Alfred Wegener...
