Abstract:

Marine sedimentary infauna alter acoustic properties of sediments by creating voids and air bubbles, manipulating grain and shell distributions, and creating surface roughness elements. To date there is little information on the rates of change of these sediment properties as a result of infaunal activities. Recent studies suggest that organisms move locally in response to transient ecological and geochemical events. Such movements will create significant change in sediment physical structure on short spatial and temporal scales.
