In 1991, the JASON Remotely Operated Vehicle (ROV) successfully performed high-resolution imaging within complex vent fields on the northern Juan de Fuca Ridge. From June 22 to July 16, 1992, a team of Canadian and U.S. scientists and engineers joined in an expedition to develop sampling capabilities for a HYSUB 5000 ROV in a mid-ocean ridge hydrothermal vent environment. Our experience on the Juan de Fuca Ridge is another starting point for pursuing the science capabilities of deep-water ROVs.

The Remotely Operated Platform for Ocean Science (ROPOS) was built by International Submarine Engineering and is operated by the Institute of Ocean Sciences in Sidney, British Columbia. The cruise was staged off the National Oceanic and Atmospheric Administration's ship Discoverer, based at NOAA's Pacific Marine Center in Seattle, Wash. Support for the expedition came from the Department of Fisheries and Oceans Canada, the Department of Energy Mines and Resources Canada, the NOAA Vents Program, and the Natural Sciences and Engineering Research Council Canada.
