An Analysis of Upper Ocean Sound Speed Variability and its Effects on Long-Range Acoustic Fluctuations Observed for the North Pacific Acoustic Laboratory

: The objectives of this work are to quantification of ocean sound speed space-time scales due to internal waves, mesoscale eddies, internal tides, and other fine structures through the analysis of an extensive oceanographic data set collected during North Pacific Acoustic Laboratory (NPAL) field year between summer 1998 and summer 1999, and establish the connections between oceanic and acoustic variability.
