Measuring the Spatial Distribution of Ripples Using a REMUS AUV

Abstract

The long term goal is to develop and apply new technology to make better measurements of the spatial distribution of bedforms in both low wave conditions and especially in more energetic conditions. The specific objectives of this program are 1) to develop the capability in an autonomous underwater vehicle to measure bedform amplitude with resolution of 1 cm in the vertical and several cm in the horizontal direction; 2) to apply this technology in the Ripples DRI program to resolve the along- and across-shelf variations of bedform amplitude and wavelength across the West Florida shelf during varying wave-forcing conditions; 3) to make surveys in the strongly forced inner shelf region near the Martha s Vineyard Coastal Observatory to examine short-term changes in bedforms due to changes in wave forcing and to test the ability of the system to measure topography during energetic conditions.
