  • Deep ocean circulation and transport where the East Pacific Rise at 9–10°N meets the Lamont seamount chain 

    Lavelle, J. William; Thurnherr, Andreas M.; Ledwell, James R.; McGillicuddy, Dennis J.; Mullineaux, Lauren S. (American Geophysical Union, 2010-12-31)
    We report the first 3-D numerical model study of abyssal ocean circulation and transport over the steep topography of the East Pacific Rise (EPR) and adjoining Lamont seamount chain in the eastern tropical Pacific. We begin ...
  • Hydrography and circulation near the crest of the East Pacific Rise between 9° and 10°N 

    Thurnherr, Andreas M.; Ledwell, James R.; Lavelle, J. William; Mullineaux, Lauren S. (2010-12-12)
    Topography has a strong effect on the physical oceanography over the flanks and crests of the global mid-ocean ridge system. Here, we present an analysis of the hydrography and circulation near the crest of the East ...
  • Larval dispersion along an axially symmetric mid-ocean ridge 

    McGillicuddy, Dennis J.; Lavelle, J. William; Thurnherr, Andreas M.; Kosnyrev, V. K.; Mullineaux, Lauren S. (2009-12-22)
    We investigated planktonic larval transport processes along an axially symmetric mid-ocean ridge with characteristics similar to that of the East Pacific Rise (EPR) segment at 9-10°N. The hydrodynamic basis for this study ...
  • The prediction, verification, and significance of flank jets at mid-ocean ridges 

    Lavelle, J. William; Thurnherr, Andreas M.; Mullineaux, Lauren S.; McGillicuddy, Dennis J.; Ledwell, James R. (The Oceanography Society, 2012-03)
    One aspect of ocean flow over mid-ocean ridges that has escaped much attention is the capacity of a ridge to convert oscillatory flows into unidirectional flows. Those unidirectional flows take the form of relatively narrow ...
  • Rates and mechanisms of turbulent dissipation and mixing in the Southern Ocean : results from the Diapycnal and Isopycnal Mixing Experiment in the Southern Ocean (DIMES) 

    Sheen, Katy L.; Brearley, J. Alexander; Naveira Garabato, Alberto C.; Smeed, David A.; Waterman, Stephanie N.; Ledwell, James R.; Meredith, Michael P.; St. Laurent, Louis C.; Thurnherr, Andreas M.; Toole, John M.; Watson, Andrew J. (John Wiley & Sons, 2013-06-04)
    The spatial distribution of turbulent dissipation rates and internal wavefield characteristics is analyzed across two contrasting regimes of the Antarctic Circumpolar Current (ACC), using microstructure and finestructure ...
  • Surface-generated mesoscale eddies transport deep-sea products from hydrothermal vents 

    Adams, Diane K.; McGillicuddy, Dennis J.; Zamudio, Luis; Thurnherr, Andreas M.; Liang, Xinfeng; Rouxel, Olivier J.; German, Christopher R.; Mullineaux, Lauren S. (2011-03)
    Atmospheric forcing, which is known to have a strong influence on surface ocean dynamics and production, is typically not considered in studies of the deep sea. Our observations and models demonstrate an unexpected ...
  • Turbulence and diapycnal mixing in Drake Passage 

    St. Laurent, Louis C.; Naveira Garabato, Alberto C.; Ledwell, James R.; Thurnherr, Andreas M.; Toole, John M.; Watson, Andrew J. (American Meteorological Society, 2012-12)
    Direct measurements of turbulence levels in the Drake Passage region of the Southern Ocean show a marked enhancement over the Phoenix Ridge. At this site, the Antarctic Circumpolar Current (ACC) is constricted in its flow ...
