Abstract
Both active and passive acoustic remote sensing methods are used to measure ocean properties and processes. Observations are made on scales ranging from meters to megameters. Several techniques have recently matured from research to application. Beginning with active acoustics on megameter scales, there has been recent progress in basin-wide thermometry, and a global acoustic network has been suggested. On decimeter scales, active acoustics have been used to study hydrothermal flows occurring at oceanic ridges. The ultimate goal of the hydrothermal work is to measure fluxes of heat and particulates. Passive measurement of ambient sound in the ocean has been used successfully to observe a wide variety of processes at all scales. For passive acoustics, this talk will focus on small-scale determinations of rainfall rate and type, as well as studies of wave breaking.
