For the past three decades, discussion of naturally-occurring gas hydrates has been framed
by a series of assessments that indicate enormous global volumes of methane present …

Organic carbon in marine sediments is a critical component of the global carbon cycle, and
its degradation influences a wide range of phenomena, including the magnitude of carbon …

The leakage of cold, methane-rich fluids from subsurface reservoirs to the sea floor at
specific sites on continental slopes, termed cold seeps, sustains some of the richest …

It is generally assumed that oceanic gas hydrates contain a huge volume of natural gases,
mainly methane. The most widely cited estimate of global hydrate-bound gas is 21× 1015 …

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 …

In this paper, we present an equilibrium thermodynamic model to accurately predict the
maximum depth of hydrate stability in the seafloor, including the effects of water salinity …

Deep-sea sediments contain high concentrations of rare earth element (REE) which have
been regarded as a huge potential resource. Understanding the marine REE cycle is …

Microbial methane consumption in anoxic sediments significantly impacts the global
environment by reducing the flux of greenhouse gases from ocean to atmosphere. Despite …

The accumulation of methane hydrate in marine sediments is controlled by a number of
physical and biogeochemical parameters including the thickness of the gas hydrate stability …

The oxidation of methane in anoxic marine sediments is thought to be mediated by a
consortium of methane-consuming archaea and sulfate-reducing bacteria. In this study, we …
