    Pathways of Pacific Water flowing from the North Pacific Ocean through Bering Strait and across the Chukchi Sea are investigated using a two-dimensional barotropic model. In the no-wind case, the flow is driven only by a ...
  • Pathways of shelf water export from the Hatteras shelf and slope 

    Churchill, James H.; Gawarkiewicz, Glen G. (American Geophysical Union, 2012-08-21)
    It has long been recognized that a massive flow of Middle Atlantic Bight (MAB) shelf water is exported to the deep ocean in the region near Cape Hatteras, North Carolina. We examine the details of this export using data ...
  • Penetration of a salinity front into a rotating basin : laboratory experiments and a simple theory 

    Marchal, Olivier; Whitehead, John A.; Jensen, Anders (Sears Foundation for Marine Research, 2011-07-01)
    Freshwater is released along a wall of a basin containing salt water and rotating anticlockwise. The freshwater source is located near the surface between the center of the cylindrical basin and a corner along the wall. ...
