  • Explosive volcanism on the ultraslow-spreading Gakkel ridge, Arctic Ocean 

    Sohn, Robert A.; Willis, Claire; Humphris, Susan E.; Shank, Timothy M.; Singh, Hanumant; Edmonds, Henrietta N.; Kunz, Clayton G.; Hedman, Ulf; Helmke, Elisabeth; Jakuba, Michael V.; Liljebladh, Bengt; Linder, Julia; Murphy, Christopher A.; Nakamura, Ko-ichi; Sato, Taichi; Schlindwein, Vera; Stranne, Christian; Tausenfreund, Upchurch; Winsor, Peter; Jakobsson, Martin; Soule, Samuel A. (2007-11-26)
    Roughly 60% of the Earth’s outer surface is comprised of oceanic crust formed by volcanic processes at mid-ocean ridges (MORs). Although only a small fraction of this vast volcanic terrain has been visually surveyed ...
  • Long-baseline acoustic navigation for under-ice autonomous underwater vehicle operations 

    Jakuba, Michael V.; Roman, Christopher N.; Singh, Hanumant; Murphy, Christopher A.; Kunz, Clayton G.; Willis, Claire; Sato, Taichi; Sohn, Robert A. (2008-05-19)
    The recent Arctic GAkkel Vents Expedition (AGAVE) to the Arctic Ocean’s Gakkel Ridge (July/August 2007) aboard the Swedish ice-breaker I/B Oden employed autonomous underwater vehicles (AUVs) for water-column and ocean ...
  • Lossy compression and real-time geovisualization for ultra-low bandwidth telemetry from untethered underwater vehicles 

    Murphy, Christopher A. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2008-09)
    Oceanographic applications of robotics are as varied as the undersea environment itself. As underwater robotics moves toward the study of dynamic processes with multiple vehicles, there is an increasing need to distill ...
  • Progressively communicating rich telemetry from autonomous underwater vehicles via relays 

    Murphy, Christopher A. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2012-06)
    As analysis of imagery and environmental data plays a greater role in mission construction and execution, there is an increasing need for autonomous marine vehicles to transmit this data to the surface. Without access ...
  • Toward extraplanetary under-ice exploration : robotic steps in the Arctic 

    Kunz, Clayton G.; Murphy, Christopher A.; Singh, Hanumant; Pontbriand, Claire W.; Sohn, Robert A.; Singh, Sandipa; Sato, Taichi; Roman, Christopher N.; Nakamura, Ko-ichi; Jakuba, Michael V.; Eustice, Ryan M.; Camilli, Richard; Bailey, John (2009-01-12)
    This paper describes the design and use of two new autonomous underwater vehicles, Jaguar and Puma, which were deployed in the summer of 2007 at sites at 85°N latitude in the ice-covered Arctic Ocean to search for ...
