Seabed Texture and Evolution Studies: applying and advancing procedural methods for sonar characterization and simulation in dynamic ocean environments
Abstract
The proposed effort is to inform modeling efforts to create realistic simulations of seabed textures that can be used in sonar simulation and performance models. The broad objectives are to: 1) elucidate the role of bioturbation and hydrodynamic flow in horizontal diffusion; 2) advance procedural methods for modeling bioturbation, and 3) apply this improved understanding to synthetic data generation. The program as a whole will consist of a variety of components, including laboratory experiments, analysis of in-situ data, and advancement of in-silico methods. The unifying focus for this study will be the formation and evolution of seabed texture, and will draw upon both novel techniques developed under this program, as well as application of established techniques (e.g. procedural methods employed for computer graphics and animation). To achieve the goals three threads of investigation will be pursued 1) quantify the effects of both bioturbative and hydrodynamic processes on diffusion, or erosion, of seabed topology; 2) Link biological processes with observed diffusion phenomena to develop biologically driven physics based procedural methods for seabed realizations; 3) Apply the effects and processed investigated in topics 1 and 2 to generate simulated sonar imagery.
