Studies of the Internal Tide in the Lower Bay of Fundy
MetadataShow full item record
Observations from the lower Bay of Fundy in 2002 show the presence of energetic high-frequency internal wave packets that are phase-locked to the tidal cycle. An analysis of the observations provides the direction of propagation and suggests several likely generation sites. To investigate farther a finite element sigma layer model (QUODDY) is used to simulate oceanic conditions consistent with a typical September. The model is run with increased resolution over the lower Bay of Fundy. Although, the model is hydrostatic and thus incapable of simulating the eventual transformation of the internal tide into a soliton train, we hope that the model can resolve the generation processes and initial propagation of the wave. Of particular interest is the possibility that the internal tide could play a role in changing the dynamics of the tidal currents (magnitude and phase) in the stratified lower Bay. The model results will be discussed with a particular focus on the sensitivities, and overall capacity of the model to resolve internal waves. On-going work involving the use of the Finite Volume Coastal Ocean Model (FVCOM) to study the same processes will also be addressed.
