During the Shallow Water Acoustic Experiment 2006 (SW06), detailed measurements of the time-varying ocean environment were made while simultaneously acoustic signals were transmitted between various source and receiver pairs. The time-varying environment induced by internal waves (IW) was recorded by an array of moored thermistor chains, as well as by the attending research vessels. Using a mapping technique described by Badiey et al. [J. Acoust. Soc. Am. EL. 134 (2013)], the three-dimensional (3D) temperature field for over a month of IW events was reconstructed. The results of this mapping are used for the statistical analysis of the IW parameters, such as the IW propagation speed, direction, amplitude, coherence length, etc. This paper provides a summary of these results and also examines the implications of the detailed statistics as regards to the acoustic field. The results in this paper could be used as a database for studying the IW generation, propagation, and its impact on the 3D acoustic propagation in waveguides. [Work supported by ONR322OA.]
