摘要
A detailed physical model of the life history of a typical bubble plume, from Its formation by a breaking wave to its dissipation into the background bubble populaton, is set down, and the relationship be the early, acousticlly relevant stage in bubble-plume deveopment and the associated, remotely detectable whitecap is decribed. The manner in which the fraction of the sea surface covered by Stage A spilling crests and by Stage B nature whiteaps depnds upon wind spe and upon wind stress or “friction veloity” is investgated. Formal expresions are given whereby near-surfac bubble concentations can be etimated from obsrvatons of frctional whitecap coverage or from measurements of the 10-m elevaton Wind speed. © 1990 IEEE
