Abstract : Continental slopes are dynamic features evolving in response to sediment delivery and sediment redistribution by gravitational and other forces. A crucial element to understanding slope stratigraphic sequences, in time and space, is the delineation of stratal geometries, lateral and vertical variability, and three dimensional geometry of the discrete depositional units. A numerical approach to this problem has the advantage of allowing for the study of a wider range of conditions than can be observed easily in the field, or scaled within a laboratory. Therefore the long term goals of this project are to develop or improve upon existing numerical models useful for the simulation of sediment delivery and accumulation on continental margins over time scales of tens to thousands of years. Model predictions will help us understand the evolution of slope structure and sediment character on continental margins as a function of sea level, terrestrial sediment delivery, and other relevant factors. ONR interests include the development of a numerical predictor of the acoustic signature of slope margins based on a region's geological history.
