Continuation of extensive data processing and analysis of Shallow Water 2006 Experiment (SW06)
Abstract
The proposed research will focus on sound speed field pertubation by: 1) internalgravity wave groups associated with the internal tide and 2) moving interleaving water masseswith distinctive temperature and salinity properties, i.e. different sound speed fields. Both areknown to perturb the continental shelf~s sound speed field and often are present in and movethrough acoustic signal propagation paths simultaneously. Consequently, the temporal andspatial variability in the sound speed field is often the result of the combined motion of both theinternal wave fields and water masses. The relative importance of the two fluid dynamicprocesses has not been adequatedly documented nor has the impact of the seasonal variability ofthe sound speed field on acoustic signal properties. This research project will continue toquantify the effects the two processes have on the temporal and spatial variability of acousticsignals propagating through the perturbed sound speed profiles. Two frequency bands will beaddressed: 1) initially a low frequency band (50 to 500 Hz) and 2) in the future the midfrequency band (500 Hz to 4 kHz). Data taken during the summer time Shallow Water SW06experiment will be the focus of the analysis.
