Effects of Biota on Backscatter: Experiments with the Portable Acoustic Laboratory (PAL)
Abstract
Two long-term goals intersect in the short-term objectives of this research. 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. This work is joint with Chris Jones of the Applied Physics Laboratory at the University of Washington. As an ocean acoustician, Jones long-term goal is to understand both the mechanisms by which benthic biota affect high-frequency (HF) 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.
