    • Formation of intrathermocline lenses by eddy–wind interaction 

      McGillicuddy, Dennis J. (American Meteorological Society, 2015-02)
      Mesoscale intrathermocline lenses are observed throughout the World Ocean and are commonly attributed to water mass anomalies advected from a distant origin. An alternative mechanism of local generation is offered herein, ...

C. (American Association for the Advancement of Science, 2016-08-17)
      The formation of the Isthmus of Panama stands as one of the greatest natural events of the Cenozoic, driving profound biotic transformations on land and in the oceans. Some recent studies suggest that the Isthmus formed ...
    • Formation of the statolith in the ctenophore Mnemiopsis leidyi 

      Tamm, Sidney L. (Marine Biological Laboratory, 2014-08-01)
      The aboral sensory organ (apical organ) of ctenophores contains a statocyst with a single large statolith. The statolith comprises living cells (lithocytes), each containing a large membrane-bound concretion. The statolith ...
    • Fortnightly tides and subtidal motions in a choked inlet

      Amplitudes of semi-diurnal tidal fluctuations measured at an ocean inlet system decay nearly linearly by 87% between the ocean edge of the offshore ebb-tidal delta and the backbay. A monochromatic, dynamical model for a ...
    • FORTY YEARS OF IAMSLIC: THE PAST, PRESENT AND FUTURE OF OUR ASSOCIATION 

      Watkins, Steve; Webster, Janet; Wible, Joe (IAMSLIC, 2015)
    • Forum for Arctic Modeling and Observational Synthesis (FAMOS) : past, current, and future activities 

      Proshutinsky, Andrey; Steele, Michael; Timmermans, Mary-Louise (John Wiley & Sons, 2016-06-03)
      The overall goal of the Forum for Arctic Modeling and Observational Synthesis (FAMOS) community activities reported in this special issue is to enhance understanding of processes and mechanisms driving Arctic Ocean marine ...
    • Forward scattering of a pulsed continuous wave signal through laminar and turbulent thermal plumes 

      Bowen, Stephen G. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1993-09)
      The results of an experiment examining the forward propagation or an acoustic signal through a buoyant plume are discussed. Two distinct testing sights were used. One made use of a small fresh water tank in NUWC to provide ...
    • Forward sound propagation around seamounts : application of acoustic models to the Kermit-Roosevelt and Elvis seamounts 

      Kim, Hyun Joe (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2009-06)
      The Basin Acoustic Seamount Scattering Experiment (BASSEX) of 2004 was conducted to measure forward-scattering around the Kermit-Roosevelt Seamount Complex in the Northeast Pacific. The BASSEX experiment was focused on ...
    • A fossil winonaite-like meteorite in Ordovician limestone : a piece of the impactor that broke up the L-chondrite parent body?
