  • High-speed dynamic soaring 

    Richardson, Philip L. (B2Streamlines.com, 2012-04)

  • High-speed robotic albatross : unmanned aerial vehicle powered by dynamic soaring 

    Richardson, Philip L. (B2Streamlines.com, 2012-06)
    Wandering albatrosses exploit the vertical gradient of wind velocity (wind shear) above the ocean to gain energy for long distance dynamic soaring with a typical airspeed of 36 mph. In principle, albatrosses could ...
  • A highly nonlinear coupled mode of decadal variability in a mid-latitude ocean–atmosphere model 

    Kravtsov, Sergey K.; Dewar, William K.; Berloff, Pavel S.; McWilliams, James C.; Ghil, M. (2006-08-10)
    This study examines mid-latitude climate variability in a model that couples turbulent oceanic and atmospheric flows through an active oceanic mixed layer. Intrinsic ocean dynamics of the inertial recirculation regions ...

    Sanford, Thomas B.; Price, James F.; Girton, James B.; Webb, Douglas C. (American Geophysical Union, 2007-07-07)
    An autonomous, profiling float called EM-APEX was developed to provide a quantitative and comprehensive description of the ocean side of hurricane-ocean interaction. EM-APEX measures temperature, salinity and pressure to ...
  • Horizontal advection, diffusion, and plankton spectra at the sea surface 

    Bracco, Annalisa; Clayton, Sophie A.; Pasquero, Claudia (American Geophysical Union, 2009-02-04)
    Plankton patchiness is ubiquitous in the oceans, and various physical and biological processes have been proposed as its generating mechanisms. However, a coherent statement on the problem is missing, because of both a ...
  • Horizontal and vertical structure of velocity, potential vorticity and energy in the Gulf Stream 

    Hall, Melinda M. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1985-02)
    From October, 1982 to October, 1983 a current meter mooring reaching from the bottom into the thermocline was deployed for the first time in the Gulf Stream at 68°W. The temperatures, pressures, and velocities at the ...
  • Horizontal density structure and restratification of the Arctic Ocean surface layer 

    Timmermans, Mary-Louise; Cole, Sylvia T.; Toole, John M. (American Meteorological Society, 2012-04)
    Ice-tethered profiler (ITP) measurements from the Arctic Ocean’s Canada Basin indicate an ocean surface layer beneath sea ice with significant horizontal density structure on scales of hundreds of kilometers to the order ...
  • Horizontal eddy energy flux in the world oceans diagnosed from altimetry data 

    Xu, Chi; Shang, Xiao-Dong; Huang, Rui Xin (Nature Publishing Group, 2014-06-17)
    During the propagation of coherent mesoscale eddies, they directly or indirectly induce many effects and interactions at different scales, implying eddies are actually serving as a kind of energy carrier or energy source ...
  • The horizontal mooring : a two-dimensional array, description of the array, components, instrumentation, deployment and recovery operations 

    Trask, Richard P.; Anderson, Steven P.; Way, Bryan S.; Ostrom, William M.; Paul, Walter; Grosenbaugh, Mark A.; Gobat, Jason I.; Weller, Robert A. (Woods Hole Oceanographic Institution, 1999-09)
    A moored two-dimensional array with instrumentation distributed both horizontally and vertically was deployed for 27 days in August 1998 at an 85 meter deep site in Massachusetts Bay near Stellwagon basin. The horizontal ...
  • Horizontal scales of variability over the Middle Atlantic Bight shelf break and continental rise from finescale observations 

    Todd, Robert E.; Gawarkiewicz, Glen G.; Owens, W. Brechner (American Meteorological Society, 2013-01)
    Observations with fine horizontal resolution are used to identify the horizontal scales of variability over the Middle Atlantic Bight (MAB) shelf break and continental rise. Spray gliders collected observations along two ...
  • How do albatrosses fly around the world (almost) without flapping their wings? 

    Richardson, Philip L. (2010-08-26)
    Albatrosses fly long distances over the Southern Ocean, even around the world (almost) without flapping their wings, which has raised interest in how they perform such a feat. On a cruise to the South Atlantic I observed ...
  • How does Labrador Sea Water enter the deep western boundary current? 

    Palter, Jaime B.; Lozier, M. Susan; Lavender, Kara L. (American Meteorological Society, 2008-05)
    Labrador Sea Water (LSW), a dense water mass formed by convection in the subpolar North Atlantic, is an important constituent of the meridional overturning circulation. Understanding how the water mass enters the deep ...

    Wåhlin, A. K.; Cenedese, Claudia (2005-11-03)
    The sensitivity of the basin-scale ocean stratification to the vertical distribution of plume entrainment is being analyzed. A large ocean basin supplied by dense water from an adjoining marginal sea is considered. The ...
  • How is the ocean filled? 

    Gebbie, Geoffrey A.; Huybers, Peter (American Geophysical Union, 2011-03-23)
    The ocean surface rapidly exchanges heat, freshwater, and gases with the atmosphere, but once water sinks into the ocean interior, the inherited properties of seawater are closely conserved. Previous water-mass decompositions ...
  • How much did Glacial North Atlantic Water shoal? 

    Gebbie, Geoffrey A. (John Wiley & Sons, 2014-03-13)
