| Description |
Upper layer temperature in the western Philippine Sea near Taiwan was sampled using a coastal monitoring buoy with fifteen themistors attached from July 28-August 7, 2005. Internal waves and internal solitons were identifed during the empirical orthogonal function analysis. Without the IW and IS, the power spectra, structure functions, and singular measures (respresenting the intemittency) of the temprature field satisfy the power law with multi-scale characteristics at all depths. The IW does not change the basic characteristics of the multifractal structure. However, the IS changes the power exponent of the power spectra drastically, especially in the low wave number domain. It breaks down the power law of the structure function and increases the intermittency parameter. The physical mechanisms causing these different effects need to be explored futher. The Comprehansive Acoustic Simulation System was applied to determine how the IS affect the mines detection by computing the transmission loss (TL) and the ray traces of rand-dependent and range independent cases during the IS period. The maximum TL difference is 20 dB. As a result, the mine detection probability will dramatically be reduced to 1% of the original detection probability.
