Wave Breaking, Bubble Production and Acoustic Characteristics of the Surf Zone, SIO Component

摘要

The objective of the research component reported here was to make long-term measurements of acoustic telemetry and channel probe signals propagated through the surf zone simultaneously with measurements of the shoaling surf, the clouds of bubble entrained by breaking waves and the nearshore circulation driving bubble advection. The purpose of these measurements was to: (1) statistically characterize the surf zone acoustic channel Doppler and time spreads, and acoustic drop-outs, in terms of the incident wave field and (2) make sufficiently detailed environmental and acoustic measurements to understand the deterministic coupling between the telemetry signals, the surface gravity wave field and wave-induced bubble clouds.
