Environmental Fluctuations in Forward Scatter and Reverberation
Abstract
The objective of this research as to measure fluctuations in mid-frequency (roughly 1-10 kHz) shallow water forward scatter and reverberation due to time-evolving variability in the sea surface and water column environment as well as source motion. The observations were used to quantify the uncertainty in seafloor geoacoustic inversions due to environmental variability and their subsequent use in reverberation level predictions. The focus of this research is on understanding the relationship between fluctuations in mid-frequency shallow water forward scatter and reverberation due to time-evolving variability in the sea surface and water column environment as well as source motion. In addition, the impact of environmental variability on the uncertainty in mid-frequency seafloor geoacoustic inversions and their subsequent use in reverberation level predictions is of interest. A major component of this project has been participation in the planning and execution of the ONR Target and Reverberation Experiment 2013 (TREX13) which was carried out in April-May 2013 off Panama City, FL.
