    • Autonomous and remotely operated vehicle technology for hydrothermal vent discovery, exploration, and sampling 

      Yoerger, Dana R.; Bradley, Albert M.; Jakuba, Michael V.; German, Christopher R.; Shank, Timothy M.; Tivey, Maurice A. (Oceanography Society, 2007-03)
      Autonomous and remotely operated underwater vehicles play complementary roles in the discovery, exploration, and detailed study of hydrothermal vents. Beginning with clues provided by towed or lowered instruments, ...
    • Diverse styles of submarine venting on the ultraslow spreading Mid-Cayman Rise 

      German, Christopher R.; Bowen, Andrew D.; Coleman, M. L.; Honig, D. L.; Huber, Julie A.; Jakuba, Michael V.; Kinsey, James C.; Kurz, Mark D.; Leroy, S.; McDermott, Jill M.; Mercier de Lepinay, B.; Nakamura, Ko-ichi; Seewald, Jeffrey S.; Smith, J. L.; Sylva, Sean P.; Van Dover, Cindy L.; Whitcomb, Louis L.; Yoerger, Dana R. (2010-06-24)
      Thirty years after the first discovery of high-temperature submarine venting, the vast majority of the global Mid Ocean Ridge remains unexplored for hydrothermal activity. Of particular interest are the world’s ultra-slow ...
    • 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 ...
    • Influence of ice thickness and surface properties on light transmission through Arctic sea ice 

      Katlein, Christian; Arndt, Stefanie; Nicolaus, Marcel; Perovich, Donald K.; Jakuba, Michael V.; Suman, Stefano; Elliott, Stephen M.; Whitcomb, Louis L.; McFarland, Christopher J.; Gerdes, Rudiger; Boetius, Antje; German, Christopher R. (John Wiley & Sons, 2015-09-04)
      The observed changes in physical properties of sea ice such as decreased thickness and increased melt pond cover severely impact the energy budget of Arctic sea ice. Increased light transmission leads to increased deposition ...
    • 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 ...
    • Mid-ocean ridge exploration with an autonomous underwater vehicle 

      Yoerger, Dana R.; Bradley, Albert M.; Jakuba, Michael V.; Tivey, Maurice A.; German, Christopher R.; Shank, Timothy M.; Embley, Robert W. (Oceanography Society, 2007-12)
      Human-occupied submersibles, towed vehicles, and tethered remotely operated vehicles (ROVs) have traditionally been used to study the deep seafloor. In recent years, however, autonomous underwater vehicles (AUVs) have ...
    • 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 ...
