James River Estuary Acoustic Field Experiment

The James River Estuary acoustic field experiment of 2019 (JRE2019) was designed to focus on acoustic characteristics of the James River estuarine environment using simple instrumentation, and correlate the acoustical characteristics to observational parameters such as current profiles and geological descriptors. A central objective is the investigation of the impact of bubbles on sound propagation within the estuarine front. Experimentation was conducted over an 8-day period in April, 2019, and was sponsored by the Office of Naval Research (ONR). This report provides technical details of the logistics, instrumentation, execution and initial results of the acoustical observations made during this field effort. Further analysis and results will be published separately in scientific journal articles.
