      New Bedford Harbor and its approaches form the estuary of the Acushnet River in southeastern Massachusetts. The estuary is weakly stratified and only partially mixed because river discharge is very small. It appears to ...

      Draut, Amy E. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2003-06)
      This thesis examines the evolution of a mud-dominated coastal sedimentary system on multiple time scales. Fine-grained systems exhibit different properties and behavior from sandy coasts, and have received relatively ...

      Sohn, Robert A.; Webb, Spahr C.; Hildebrand, John A. (American Geophysical Union, 2004-12-09)
      We use a combination of body wave and interface wave observations from an on-bottom seismic refraction survey to constrain the fine-scale seismic structure of the upper crust in a ∼3 × 3 km field area centered on the East ...

      This article (1) reviews and clarifies the basic physics underpinning finescale parameterizations of turbulent dissipation due to internal wave breaking and (2) provides advice on the implementation of the parameterizations ...
    • Finescale structure of the T-S relation in the eastern North Atlantic 

      Ferrari, Raffaele; Polzin, Kurt L. (American Meteorological Society, 2005-08)
      Distributions of temperature (T) and salinity (S) and their relationship in the oceans are the result of a balance between T–S variability generated at the surface by air–sea fluxes and its removal by molecular dissipation. ...
    • Finestructure and turbulence in the deep ocean 

      Hendricks, Peter J. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1977-01)
      Millimeter scale fluctuations in refractive index recorded with a freely sinking shadowgraph system are correlated with finestructure profiles of temperature, salinity and density and compared to models of ocean turbulence. ...
    • Finger puzzles 

      Schmitt, Raymond W. (Cambridge University Press, 2012-01-24)
      Salt fingers are a form of double-diffusive convection that can occur in a wide variety of fluid systems, ranging from stellar interiors and oceans to magma chambers. Their amplitude has long been difficult to quantify, ...
    • Finite difference modeling of geoacoustic interaction at anelastic seafloors 

      Stephen, Ralph A.; Swift, Stephen A. (Acoustical Society of America, 1994-01)
      A major problem in understanding seismic wave propagation in the seafloor is to distinguish between the loss of energy due to intrinsic attenuation and the loss of energy due to scattering from fine scale heterogeneities ...
    • A finite volume numerical approach for coastal ocean circulation studies : comparisons with finite difference models 

      Chen, Changsheng; Huang, Haosheng; Beardsley, Robert C.; Liu, Hedong; Xu, Qichun; Cowles, Geoffrey W. (American Geophysical Union, 2007-03-28)
      An unstructured grid, finite volume, three-dimensional (3-D) primitive equation coastal ocean model (FVCOM) has been developed for the study of coastal ocean and estuarine circulation by Chen et al. (2003a). The finite ...
