Transmission Electron Microscopy (TEM) observations confirm theoretical predictions of the location of organic matter (OM) sequestered in fine-grained sediment. Organo-clay micro- and nanoscale fabric images validate for the first time the protective

We employed direct visualization of organic matter (OM) sequestered by microfabric signatures in organo-clay systems to study mechanisms of OM protection. We studied polysaccharides, an abundant class of OM in marine sediments, associated with the na

Porosity is a fundamental property of marine sediment from which wet bulk density can be easily determined and used in a variety of geoacoustic, geotechnical, and sedimentological studies, analyses, and models. However, methods of sampling marine san

Study of marine sediment pore fluid pathways and porometry requires careful analysis of the fabric of "undisturbed" sediment samples. A novel solution to the preservation of the interstitial organic material and the in situ fabric or sedimentary stru

The sediment at the interface immediately beneath the water column is distinct from deeper-lying sediments in its properties and, at least quantitatively, in the processes driving diagenesis. Progress in understanding thesediment-water interface can

The physical and dynamic properties of marine mud are a function of the interaction of clay fabric, organic matter (OM), and seawater physico-chemistry, and, when present, free gas. OM is the focus of this presentation and is a determinant of several

High-resolution (scales of 2.5 mm to submicrometer), interdisciplinary studies of California continental slope sediments (0–80 cm) reveal the importance of marine organic material and mineralogy on mass physical properties in fine-grained sediments

Microbes, their exocellular secretions, and their impact on the mineralogy and microfabric of fine-grained continental margin sediments were investigated by transmission electron microscopy. Techniques were used that retained the in situ spatial rela

Knowledge of basic clay microstructure is fundamental to an understanding of the physical, chemical, and mechanical properties of fine-grained sediments and rocks. This compilation of fifty-nine peer-reviewed papers examines clay microstructure in de
