    Few models of double-diffusive interleaving apply to the finite-amplitude phase of interleaving growth. Of these, none consider the dynamics in baroclinic fronts. Here, a new theoretical model is developed for the ...
  • Evidence of wind-driven upwelling in Jacques-Cartier Strait 

    Bourque, MC, and DE Kelley. 1995. "Evidence of wind-driven upwelling in Jacques-Cartier Strait." Atmosphere-Ocean 33(4): 621-637.
    Satellite images of the Gulf of St. Lawrence show a persistent band of cold water along the north coast of Jacques-Cartier Strait during summer. A possible explanation is that the wind is causing upwelling of deep water. ...
  • Inferring Propagation Direction of Nonlinear Internal Waves in a Vertically Sheared Background Flow 

    Mirshak, Ramzi, and Daniel E. Kelley. 2009. "Inferring Propagation Direction of Nonlinear Internal Waves in a Vertically Sheared Background Flow." Journal of Atmospheric and Oceanic Technology 26(3): 615-625.
    Internal waves heave the background flow through which they propagate. If the background flow is vertically sheared, the high-pass-filtered velocity field will thus contain signals of both the wave velocity and the heaved ...

    [1] This study examines variability in the relationship between Sun-induced chlorophyll fluorescence and incident solar irradiance as a potential diagnostic of the nutritional status of phytoplankton. The study site is the ...
  • The importance of small-scale turbulence in the feeding of herring larvae

    Herring larvae form a large, persistent and well-defined aggregate off southwest Nova Scotia coincident with a region of strong tidally generated turbulence. Our objective is to test the hypothesis that turbulent, tidally ...
  • Potential contributions of vertically migrating Rhizosolenia to nutrient cycling and new production in the open ocean 

    Richardson, TL, JJ Cullen, DE Kelley, and MR Lewis. 1998. "Potential contributions of vertically migrating Rhizosolenia to nutrient cycling and new production in the open ocean." Journal of Plankton Research 20(2): 219-241.
    We present a numerical model of nutrient uptake and photosynthesis during migrations of the marine diatom Rhizosolenia that was developed to estimate fluxes of carbon and nitrogen due to these migrations in the open ocean. ...
  • Nearshore circulation and synthetic aperture radar: An exploratory study 

    Thompson, K. R., D. E. Kelley, D. Sturley, B. Topliss, et al. 1998. "Nearshore circulation and synthetic aperture radar: An exploratory study." International Journal of Remote Sensing 19(6): 1161-1178.
    We use a sequence of synthetic aperture radar (SAR) images to map differences in the flood and ebb tidal currents in a cove along the coast of Nova Scotia, Canada. The asymmetry in the tidal flow determines the flushing ...

  • Wave-induced boundary mixing in a partially mixed estuary 

    Bourgault, D., and DE Kelley. 2003. "Wave-induced boundary mixing in a partially mixed estuary." Journal of Marine Research 61(5): 553-576.
    We present observations that reveal the existence of horizontally propagating, tidally-driven, high-frequency internal wave (IW) packets in a channel of the partially mixed St. Lawrence Estuary. The packets propagate ...

    Bourgault, D., DE Kelley, and PS Galbraith. 2005. "Interfacial solitary wave run-up in the St. Lawrence Estuary." Journal of Marine Research 63(6): 1001-1015.
    Density variations show evidence of interfacial solitary waves (ISW) running up the sloping boundary of an island in the St. Lawrence Estuary, confirming inferences based remote sensing. Further detail is suggested by ...
  • Turbulence and boluses on an internal beach 

    Bourgault, Daniel, Dan E. Kelley, and Peter S. Galbraith. 2008. "Turbulence and boluses on an internal beach." Journal of Marine Research 66(5): 563-588.
    In a manner similar to that of surface waves on beaches, high-frequency interfacial waves (IWs) may break when approaching the 'internal coastline, where the undisturbed pycnocline intersects the shoaling bottom. This ...
