Abstract : The Target and Reverberation EXperiment 2013 (TREX13) included a comprehensive reverberation field project in the frequency band of2-10 kHz, and was carried out off the coast of Panama City, Florida, from 21 April to 16 May, 2013. A spatially fixed transmit and receive acoustic system was used to measure reverberation over time under diverse environmental conditions, allowing study of reverberation level dependence on bottom composition, sea surface conditions, and water column properties. Extensive in situ measurements, including a multibeam bathymetric survey, chirp sonar sub-bottom profiling, gravity/diver cores, sediment sound speed and attenuation, interface roughness, wind-generated sea surface waves, and water column properties, were made to support studies of environmental effects on reverberation. Data analysis from TREX13 resulted in a set of publications which documents progress made under this project.
