The seabed plays a key role in the marine carbon cycle as a) the terminal location of aerobic
oxidation of organic matter, b) the greatest anaerobic bioreactor, and c) the greatest …

Benthic O2 availability regulates many important biogeochemical processes and has crucial
implications for the biology and ecology of benthic communities. Further, the benthic O2 …

Over the past fifteen years a limited number of monographs concerned with the theory of
transport and reaction of substances in sediments (Berner, 1980; Lerman, 1979; and in part …

Some bacteria are capable of extracellular electron transfer, thereby enabling them to use
electron acceptors and donors without direct cell contact,,,. Beyond the micrometre scale …

Understanding the labile status of phosphorus (P) in sediments is crucial for managing a
eutrophic lake, but it is hindered by lacking in situ data particularly on a catchment scale. In …

Most of the present formulations for the mass conservation of species do not correctly
represent changes in the time scale of diffusion as a function of porosity in a system of …

Use of Fick's First Law to estimate solute fluxes is arguably the most common and important
calculation related to the geochemistry and environmental chemistry of fine-grained …

The naturally occurring isotope radon-222 (222 Rn) is widely employed as a tracer for
groundwater discharge to lakes, lagoons, rivers, estuaries, and coastal oceans. Owing to the …

The composition of any environment or object is determined by a particular balance
between material transport processes and chemical reactions within and around it. In the …

For more than a decade I have taught a graduate-level course in marine sediment
geochemistry that covers many of the topics discussed in this book. The goal now is to …
