Seafloor Sediment Environmental Measurements in Support of High Frequency Sound Interaction in Ocean Sediments

Abstract

The project is directed toward the quantification of selected sediment properties crucial to the modeling of high frequency sound interaction in ocean sediments. The effort is two-fold. One part of the research is to introduce a novel instrument and approach to making in situ three-dimensional measurements of sediment permeability. The second part of the research is to perform a study of the sediment microfabric that will lead to a better understanding of the sediment pore fluid pathways and porometry. The long-term goal is the development of microfabric models that describe important sediment properties such as fluid flow characteristics, isotropy and anisotropy, stress-strain behavior, and 3-D space pore geometry where water, gas, and biogenic materials are found (Bennett et al. 1989, 1996, 1999 a and b).
