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 …

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 …

Rhizon samplers were originally designed as micro‐tensiometers for soil science to sample
seepage water in the unsaturated zone. This study shows applications of Rhizons for …

Due to the major role played by diatoms in the biological pump of CO2, and to the presence
of silica-rich sediments in areas that play a major role in air–sea CO2 exchange (eg the …

Publisher Summary This chapter focuses on the paleoceanographical proxies based on
deep-sea benthic foraminiferal assemblage characteristics, and presents the following three …

A chapter on the pore water of sediments and the processes of early diagenesis, reflected by
the concentration profiles therein, can certainly be structured in different ways. One …

In this paper, we outline the need for a coordinated international effort toward the building of
an open-access Global Ocean Oxygen Database and ATlas (GO2DAT) complying with the …

Geochemical cycles on Earth follow the basic laws of thermodynamics and proceed towards
a state of maximal entropy and the most stable mineral phases. Redox reactions between …

Surface sediment was sampled at two bathyal sites in the southwestern Gulf of Lions in the
western Mediterranean Sea in February and August 1997 to study the distribution and …
