Multibeam Mapping of the Uncertainty of the Seafloor in the Southern East China Sea
Abstract
The long-term goal of the Quantifying, Predicting and Exploiting (QPE) Uncertainty DRI is to understand and exploit (if possible) the fundamental acoustic, oceanographic, bathymetric and geoacoustic uncertainties of the tactical naval environment, and demonstrate how they may be exploited tactically or strategically in an Exercise Area. Focussing on the seabed, our goals are to understand the fundamental tactical and strategic uncertainty of the bathymetric and geoacoustic environment, and develop methods for their representation, visualization, computation and manipulation in a manner consistent with models of sonar performance estimation and prediction. OBJECTIVES The scientific objectives of the UNH team are: 1. Understand the sources and magnitudes of bathymetric and geoacoustic uncertainty in the Southern East China Sea Exercise Area, and their implications for acoustic modelling. 2. Develop a framework methodology for expression of user-relevant uncertainty in the bathymetric and geoacoustic context. 3. Develop appropriate representation/visualization techniques for the uncertainty models developed. 4. Provide continually updated "best available" estimates of bathymetry, backscatter and uncertainty models to the QPE technical group, consistent with data access limitations.
