High-resolution Mapping and Backscatter Studies in Support of the Ripples DRI

Abstract

The long-term goal of the RIPPLES DRI is to develop the ability to predict the geometry and evolution of seafloor morphology and in particular the presence or absence of ripples which have been shown to affect the sub-seafloor penetration of acoustic energy. Specific goals are to: 1- Measure and model ripple morphology and gradients on scales ranging up to kilometers 2- Understand the response of ripples to changes in wave and wave-current forcing 3- Measure and model rates of biological degradation (or production) of seafloor morphology 4- Measure and model effects of a distribution of grain-scale properties (e.g. size, density, cohesion) on ripple morphology 5- Understand the role of ripples in generating surface and subsurface sedimentary structures.
