Nonlinear Internal Waves - A Wave-Tracking Experiment to Assess Nonlinear Internal Wave Generation, Structure, Evolution and Dissipation Over the NJ shelf
Abstract
The thrust of this project is the investigation of non-linear internal waves which appear as waves of depression when propagating on a near-surface interface and as waves of elevation when propagating on a near-bottom interface. We have had the good fortune to observe (by shipboard wave-tracking and from bottom-moorings) both waves of depression and of elevation propagating inshore from the Oregon shelf break into shallow water and have now successfully applied these types of observations to a study of waves over the New Jersey shelf. The long-term goal of this program is to understand the physics of small-scale oceanic processes including internal waves, hydraulics, turbulence and microstructure that act to perturb the circulation in coastal oceans and, in doing so, affect the propagation of sound and light. Ongoing studies within the Ocean Mixing Group at OSU emphasize observations, a continual program of sensor and instrumentation development, and interaction with turbulence modelers.
