Shallow drilling hazard assessment consists of geological/geophysical review of drill sites to
enable the avoidance or effective mitigation of problems that can affect the safe drilling of the …

Recent developments in the quantitative modeling of methane dynamics and anaerobic
oxidation of methane (AOM) in marine sediments are critically reviewed. The first part of the …

Seabed fluid flow involves the flow of gases and liquids through the seabed. Such fluids
have been found to leak through the seabed into the marine environment in seas and …

This book, whose primary aim is to describe liquefaction processes and their implications for
marine structures such as pipelines, sea outfalls, quay walls and caisson breakwaters …

At the summit of Hydrate Ridge (ODP Sites 1249 and 1250), pore fluids are highly enriched
in dissolved chloride (up to 1370 mM) in a zone that extends from near the sediment surface …

We present a discrete element model for simulating, at the grain scale, gas migration in
brine‐saturated deformable media. We rigorously account for the presence of two fluids in …

The mechanics of uncemented soft sediments during bubble growth are not widely
understood and no rheological model has found wide acceptance. We offer definitive …

Interest in describing and modeling envelope distributions of sea-floor backscatter has
increased recently, particularly with regard to high-resolution active sonar systems. Sea-floor …

In lakes and reservoirs with variable water level, gas ebullition can play a substantial role in
methane transport in the water column and to the atmosphere. However, measuring …

Understanding the nature and extent of methane production and flux in aquatic sediments
has important geochemical, geotechnical, and global climate change implications …
