At subduction zones, fluid flow, pore pressure, and tectonic processes are tightly
interconnected. Excess pore pressure is driven by tectonic loading and fluids released by …

The most significant new contributions to the study of natural gas hydrates in the past
decade have come from findings of the Ocean Drilling Program (ODP), notably legs 112 …

Subduction zones generate voluminous magma and mediate global element cycling. Fluids
are essential to this activity, yet their behavior is perhaps the most poorly understood aspect …

Processes in subduction zones such as slab and mantle‐wedge metamorphism, intraslab
earthquakes, and arc volcanism vary systematically with the age‐dependent thermal state of …

Erosion by high stress abrasion of convergent margins from horsts and grabens on the
subducting plate is not shown in seismic images. In a proposed model, the frontal sediment …

Geophysical and geological observations document that beneath the submerged forearc,
processes of sediment subduction and subduction erosion move large volumes of material …

A large number of mound-shaped structures that originated from mud extrusions is present
along the convergent continental margin off Costa Rica and Nicaragua. Active fluid venting …

LOW RES Page 1 1. INTRODUCTION The selection of Central America as a focus area by the
National Science Foundation‘s Margins Program should increase the amount of research carried …

Fluid distribution in convergent margins is by most accounts closely related to tectonics. This
association has been widely studied at accretionary prisms, but at half of the Earth's …

At Site U1325 (IODP Exp. 311, Cascadia margin), gas hydrates occupy 20–60% of pore
space in thin sand layers (< 5cm) surrounded by fine-grained intervals (2.5 m thick on …
