Effects of Biota on Backscatter: Experiments with the Portable Acoustic Laboratory

Abstract

Two long-term goals intersect in the short-term objectives of this research. As an ocean acoustician, Jones long-term goal is to understand both the mechanisms by which benthic biota affect hihigh-frequencyHF) scattering from sediments and their impacts on existing Navy models and systems. A better understanding of the biological causes of heterogeneity in sediment will add to the general understanding of HF acoustic interaction with the seafloor, aid in interpretation of HF seafloor imagery, and aid in the detection and identification of objects in biologically active sediments. P. Jumars is a biological oceanographer and is fully involved with this project, but is not listed as the PI because of his move to the University of Maine in 1999. Jumars long-term goal is to identify, quantify and understand important interactions among organisms, particles (including sediments), solutes and moving fluids. The reason for this goal is to enable solutions of interesting forward and inverse problems dealing with benthic biota.
