Dahl, Peter H.

The long term goal of this research is an improved understanding of (1) high-frequency scattering from the air-sea interface and from bubbles near this interface, and (2) high-frequency propagation and scattering in bubbly media characteristic of surf zone conditions. For studies involving the air-sea interface, the objective is to model bistatic sea surface scattering measurements based on simultaneous measurements of the wind and directional wave fields. For studies on acoustic propagation and scattering in the surf zone, the objectives is to extract attributes (e.g., void fraction, spatial and temporal scales) of a surf zone bubble field, and interpret these vis-a-vis the coastal oceanography and their impact on high-frequency acoustic systems.
