Abstract:
An overview of the Yellow Sea Oceanic Front and Internal Waves Acoustic Experiment 2005 conducted in the South Yellow Sea is presented. The experiment was a multi-institutional effort which acquired high quality environmental and acoustic data. Two of its goals were to observe internal waves including linear random and nonlinear and cold water mass of South Yellow Sea to understand and describe their effects on acoustic signals. The talk contains three primarilary experimental results. First, a comparison of data from VLA and thermistor string record suggests that nonlinear internal waves cause coherent variations of arrival time structure in frequency bands 600–800 Hz. Second, normal mode coupling due to the South Yellow Sea Front (SYSF) is observed during the experiment and is used to monitor the boundary motions of the SYSF. Finally, to interpret the “frequency dispersion” in inverted effective sound speed of sea bottom, a new fast algorithm for the inversion of bottom acoustic parameters is proposed.
