Bathymetry Estimation Using Sattelite-Based SAR Observations
Abstract
Abstract This project will deal with the determination of bathymetry in complex settings (such as navigational inlets) given observations from satellite-based SARs. The emphasis will be on deriving as much information as possible about a variety of physical phenomena (e.g. waves, currents, convergences/divergences, plume fronts) from an individual SAR image and use this variety of information to constrain bathymetry using a coupled wave-circulation modeling system and ensemble-based data assimilation methodology. The developed methods will be applied at two navigational inlet sites; namely, the New River Inlet, NC, and the Mouth of the Columbia River, OR/WA where satellite observations are already available and bathymetry estimation methods using long-dwell observations have been developed and applied. Along the way, we are proposing to help address issues related to wave-related biases in the estimation of surface currents from SAR imagery, as well as ascertain the nature of fronts visible in SAR images at the two field sites.
