  • 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 ...
  • Effects of estuarine and fluvial processes on sediment transport over deltaic tidal flats 

    Ralston, David K.; Geyer, W. Rockwell; Traykovski, Peter A.; Nidzieko, Nicholas J. (2012-01-25)
    Tidal flats at a river mouth feature estuarine and fluvial processes that distinguish them from tidal flats without river discharge. We combine field observations and a numerical model to investigate hydrodynamics and ...
  • Hydrate morphology : physical properties of sands with patchy hydrate saturation 

    Dai, S.; Santamarina, J. Carlos; Waite, William F.; Kneafsey, Timothy J. (American Geophysical Union, 2012-11-14)
    The physical properties of gas hydrate-bearing sediments depend on the volume fraction and spatial distribution of the hydrate phase. The host sediment grain size and the state of effective stress determine the hydrate ...
  • Hydrodynamic modeling of tsunamis from the Currituck landslide 

    Geist, Eric L.; Lynett, Patrick J.; Chaytor, Jason D. (Elsevier B.V., 2008-10-18)
    Tsunami generation from the Currituck landslide offshore North Carolina and propagation of waves toward the U.S. coastline are modeled based on recent geotechnical analysis of slide movement. A long and intermediate wave ...
  • Impact of periodic intermediary flows on submarine melting of a Greenland glacier 

    Sciascia, R.; Cenedese, Claudia; Nicolì, D.; Heimbach, Patrick; Straneo, Fiamma (John Wiley & Sons, 2014-10-24)
    The submarine melting of a vertical glacier front, induced by an intermediary circulation forced by periodic density variations at the mouth of a fjord, is investigated using a nonhydrostatic ocean general circulation model ...
  • Observations and numerical simulations of large-eddy circulation in the ocean surface mixed layer 

    Sundermeyer, Miles A.; Skyllingstad, Eric; Ledwell, James R.; Concannon, Brian; Terray, Eugene A.; Birch, Daniel; Pierce, Stephen D.; Cervantes, Brandy (John Wiley & Sons, 2014-11-06)
    Two near-surface dye releases were mapped on scales of minutes to hours temporally, meters to order 1 km horizontally, and 1–20 m vertically using a scanning, depth-resolving airborne lidar. In both cases, dye evolved into ...
  • Regional impact of submarine canyons during seasonal upwelling 

    Connolly, Thomas P.; Hickey, Barbara M. (John Wiley & Sons, 2014-02-12)
    A numerical model of the northern California Current System along the coasts of Washington and British Columbia is used to quantify the impact of submarine canyons on upwelling from the continental slope onto the shelf. ...
  • Sediment dispersal in the northwestern Adriatic Sea 

    Harris, Courtney K.; Sherwood, Christopher R.; Signell, Richard P.; Bever, Aaron J.; Warner, John C. (American Geophysical Union, 2008-10-29)
    Sediment dispersal in the Adriatic Sea was evaluated using coupled three-dimensional circulation and sediment transport models, representing conditions from autumn 2002 through spring 2003. The calculations accounted for ...
  • Sediment transport on the Palos Verdes shelf, California 

    Ferre, Bénédicte; Sherwood, Christopher R.; Wiberg, Patricia L. (Elsevier B.V., 2010-02-01)
    Sediment transport and the potential for erosion or deposition have been investigated on the Palos Verdes (PV) and San Pedro shelves in southern California to help assess the fate of an effluent-affected deposit contaminated ...
  • A shallow-water model for hydraulically transcritical flows 

    Rogerson, A. M. (Woods Hole Oceanographic Institution, 1999-07)
    This document describes a numerical model that was developed to study two-dimensional, reduced-gravity, shallow-water flows. When the dynamics of these flows is strongly nonlinear, the flow may become hydraulically ...
