Real-Time Measurements of Sediment Modification by Large Macrofauna

Abstract

This proposal is centered on expanding (1) our sensor capabilities to allow remote detection of organism activities in sediments utilizing porewater pressure transients, vibrations and optical methods; (2) the number of species, water depths and types of sedimentary environments within our database; and (3) the linkages of organisms activities to alteration of the acoustical, geochemical, and biotic properties of sediments. The research also fulfills three important goals within ONR s Biological and Chemical Oceanography Program: (1) to enable the prediction of the distribution and abundance of biota and their interactions with biogeochemical processes in shallow water sediments, (2) to understand how biota affect the acoustical properties of operational importance to the Navy, and (3) to explore new instruments to sample and observe biological processes.
