A threefold perspective on the role of a pockmark in benthic faunal communities and biodiversity patterns [PDF]

Deep-Sea Research Part I: Oceanographic Research Papers, 2021
Pockmarks are circular-shaped depressions that increase seabed heterogeneity and are characterized by discontinuous fluid emissions. To understand how environmental conditions of pockmarks affect the structure of macroand meiofauna, we investigated two ...

Shallow plumbing systems inferred from spatial analysis of pockmark arrays [PDF]

Marine and Petroleum Geology, 2016
This study describes and analyses an extraordinary array of pockmarks at the modern seabed of the Lower Congo Basin (offshore Angola), in order to understand the fluid migration routes and shallow plumbing system of the area. The 3D seismic visualization

Investigation on the geochemical dynamics of a hydrate-bearing pockmark in the Niger Delta

Marine and Petroleum Geology, 2013
A joint industrial project with IFREMER and Total provides insights into the tectonic setting and the geochemistry of a large active pockmark offshore W-Africa in the Niger Delta.

Shallow Gas Hydrate Accumulations at a Nigerian Deepwater Pockmark—Quantities and Dynamics [PDF]

Journal of Geophysical Research: Solid Earth, 2020
The evolution of submarine pockmarks is often related to the ascent of fluid from the subsurface. For pockmarks located within the gas hydrate stability zone, methane oversaturation can result in the formation of gas hydrates in the sediment.
