Abstract:

LONG-TERM GOALS To theoretically study low-frequency, long-range sound propagation through a fluctuating ocean, including studies of 3D effects. To compare obtained theoretical results with experimental data. OBJECTIVES To develop a new, modal, 3D theory of low-frequency, long-range sound propagation through an ocean with random inhomogeneities. Based on this theory, to develop computer codes for calculating statistical moments of a sound field propagating through the ocean with internal gravity waves, internal tides, and spiciness. To compare theoretical predictions with data obtained during the 1998-1999 and 2004 NPAL experiments.
