Estimation and Visualization of Seafloor Uncertainty.

摘要

LONG-TERM GOALS. The long-term goal of the Capturing Uncertainty DRI is to assess and characterize uncertainty in the tactical naval environment. As part of the Seafloor Variability team, the focus of our effort is to develop approaches to characterize uncertainty associated with measurements of bathymetry and other seafloor properties that are important for sonar performance predictions. We are also developing innovative methods to visualize this uncertainty. OBJECTIVES. The scientific objectives of the UNH team are: 1. Develop methods to characterize uncertainty in bathymetry from modern Multibeam Echosounder (MBES) systems. This provides information that is essential in understanding our knowledge of a fundamental driver of sonar performance. 2. Develop methods to characterize and estimate uncertainty in historical bathymetric datasets, and in the combination of historical bathymetric datasets to form compilations. 3. Develop and deploy techniques to accurately measure, in situ, key physical and acoustical properties of seafloor sediments in selective shelf environments so that we may have real estimates of the spatial scales of variability of these parameters (shared with Geoclutter and Mine Burial DRIs). 4. Develop sophisticated 3-D visualization techniques that can convey the captured uncertainty in a useful and intuitive manner.
