Quantitative 3D measurements of shoaling and breaking internal waves using SAS imagery
Abstract
To advance understanding of the evolution of, transport caused by, and dissipation of internal-wave-related features in shallow water, we will make use of the sensitivity of the acoustic field to the sound speed structures formed in shoaling process. Using acoustics to obtain quantitative information about the oceanography will necessarily involve investigation into the structures that may form as a result of the interaction of internal waves with variable topography, such as boluses propagating up the inner shelf. Models for the refraction and focusing of the acoustic field caused by internal-wave structures will be used to invert for the true sizes of boluses and the possibly to invert for changes in internal parameters of the structures as they are influenced by mixing (i.e., change in the index of refraction is a direct proxy for internal temperature in most shallow water areas).
