Repeat Surveys to Evaluate Seasonal Variability in Seafloor and Shallow Sub-surface Acoustic Properties, Shallow Water Gulf of Mexico

Abstract

The long-term goals of this project is to investigate the seasonal variability in seafloor and shallow sub-bottom acoustic properties in the shallow water Gulf of Mexico. We have chosen three sites for this purpose: MURI Fluid-Mud site, Louisiana; West Delta area, Louisiana; and Panama City, Florida. Our objective in all study areas is to increase our understanding of the variability of seafloor and shallow sub-surface acoustic properties that impact the ability to identify anthropogenic objects in the nearshore environment. Specifically, the present work is relevant to enhancing ONR's understanding of surface and subsurface seafloor geological characteristics, including geoacoustical and geotechnical properties. We are interested in determining differences in seafloor acoustic signatures between frequencies (same area, same time), and between seasons (same area, same frequency, different time).
