    • Laboratory observations of enhanced entrainment in dense overflows in the presence of submarine canyons and ridges 

      Wåhlin, A. K.; Darelius, Elin; Cenedese, Claudia; Lane-Serff, G. F. (2008-01-29)
      The continental slopes in the oceans are often covered by small-scale topographic features such as submarine canyons and ridges. When dense plumes, flowing geostrophically along the slope, encounter such features they ...

      Whitehead, John A.; Bradley, Keith (2005-01-14)
      A simplified box model of the cooling of a salt-stratified ocean has been constructed in the laboratory to test a theory that predicts multiple equilibria if certain conditions exist. An isothermal basin of water had a ...

      Wells, Judith R. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2003-02)
      Oceanic observations indicate that abyssal mixing is localized in regions of rough topography. How locally mixed fluid interacts with the ambient fluid is an open question. Laboratory experiments explore the interaction ...

    • Large-scale alignment of oceanic nitrate and density 

      Omand, Melissa M.; Mahadevan, Amala (John Wiley & Sons, 2013-10-15)
      By analyzing global data, we find that over large scales, surfaces of constant nitrate are often better aligned with isopycnals than with isobars, particularly below the euphotic zone. This is unexplained by the movement ...

      Harpold, A. A.; Marshall, J. A.; Lyon, S. W.; Barnhart, T. B.; Fisher, B. A.; Donovan, M.; Brubaker, K. M.; Crosby, C. J.; Glenn, N. F.; Glennie, C. L.; Kirchner, P. B.; Lam, N.; Mankoff, Kenneth D.; McCreight, J. L.; Molotch, N. P.; Musselman, K. N.; Pelletier, J.; Russo, T.; Sangireddy, H.; Sjooberg, Y.; Swetnam, T.; West, N. (Copernicus Publications on behalf of the European Geosciences Union, 2015-06-22)
      Observation and quantification of the Earth's surface is undergoing a revolutionary change due to the increased spatial resolution and extent afforded by light detection and ranging (lidar) technology. As a consequence, ...
