Abstract:

This project is centered on expanding 1 our sensor capabilities to allow remote detection of organism activities in sediments utilizing porewater pressure transients and optical methods 2 the number of species, water depths and types of sedimentary environments within our database 3 our ability to measure labile organics optically and 4 the linkages of organisms activities to alteration of the acoustical, geochemical, and biotic properties of sediments. The research also fulfills three important goals within ONRs 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.
