VISIONS ’15 work is scheduled at the cabled observatory's main study sites: two (Axial Base and Axial Caldera) are associated with Axial Seamount, an active underwater volcano 300 miles west of Astoria, Oregon; one is at the base of the continental slope, 60 miles west of Newport, Oregon; one is on the continental shelf at Southern Hydrate Ridge, the site of active methane seeps and methane-ice deposits. Two other cabled sites on the continental shelf (Inshore and Offshore) are associated with the Endurance Array, the OOI coastal component led by Oregon State University.
