      Beem, Heather R.; Triantafyllou, Michael S. (2015-08)
      Blindfolded harbour seals are able to use their uniquely shaped whiskers to track vortex wakes left by moving animals and identify objects that passed by 30 s earlier, an impressive feat, as the flow features have velocities ...

      Laible, Henry A. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1995-09)
      The goal of this thesis is to be able to predict acoustic wave speeds in sea ice with known concentrations of inhomogeneities. To accomplish this, ice is modeled as a solid in which cylindrical fluid brine channels are ...

      Hsu, Tian-Jian; Elgar, Steve; Guza, R. T. (2006-04-06)
      The 25-m onshore migration of a nearshore sandbar observed over a 5-day period near Duck, NC is simulated with a simplified, computationally efficient, wave-resolving singlephase model. The modeled sediment transport is ...
    • Waves in the Red Sea : response to monsoonal and mountain gap winds 

      Ralston, David K.; Jiang, Houshuo; Farrar, J. Thomas (2013-05-30)
      An unstructured grid, phase-averaged wave model forced with winds from a high resolution atmospheric model is used to evaluate wind wave conditions in the Red Sea over an approximately 2-year period. The Red Sea lies in a ...
