BSGF - Earth Sciences Bulletin, 2017 Based on a High-Resolution 3D seismic block acquired in the Gulf of Lion in 2004–2005 we investigated fluid pipes and pockmarks on the top of the interfluve between the Hérault canyon and the Bourcart canyon both created by turbidity currents and gravity

National Relics: Secular Sacrality, Museums, and Heritage‐Making in Nineteenth‐Century Chile
Museum Anthropology, Volume 49, Issue 2, Fall 2026.ABSTRACT This article examines how objects and bodily remains are transformed and ritualized into national relics through collecting and exhibiting practices in museums. Focusing on nineteenth‐century Chile, it draws on archival sources, material culture theory, and the anthropology of religion to argue that objects associated with Chile's nation‐state

Ecology of a North Sea pockmark with an active methane seep [PDF]
, 1991 : At a large North Sea pockmark, with active methane seeps, surface sediments were found to have higher insoluble sulphide concentrations than sedlments from the surrounding area.

Estuarine Pockmark Field Dynamics and Evolution
, 2011 Pockmarks are one the largest, most ubiquitous types of marine landforms in world. Common in areas with gas hydrates or underlying thermogenic fluids, pockmarks are not well understood in nearshore settings lacking such extensive subsurface fluid sources.

Cyclic Pockmark Formation Linked to Plio‐Pleistocene Sea‐Level Rise on the Chatham Rise, New Zealand
Geochemistry, Geophysics, GeosystemsPockmarks are geomorphological depressions on the seafloor in various underwater environmental settings. They are commonly linked to fluid release from subsurface reservoirs; however, the processes involved, fluid types, and relative timing of their ...

Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.Abstract The Siple Coast region of West Antarctica is known for its fast flowing, topographically unconstrained ice streams that evolve due to subglacial conditions. In this work, we analyze the nature of the Siple Coast subglacial hydrologic system and its interactions with the ice sheet using two‐way coupled subglacial hydrology and ice flow modeling.

A Vast Valley Network Beneath the Greenland Ice Sheet
Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.Abstract Mapping subglacial topography along the margin of the Greenland Ice Sheet was revolutionized by reconciling measurements of ice thickness and surface velocity using the principle of mass conservation. Despite evidence that many subglacial valleys resolved by that method extend upstream, it cannot be applied to the ice sheet's slower‐flowing ...

Pockmark Flow Structure in Belfast Bay, Maine
, 2012 Pockmarks are large, circular or elongate depressions in the seafloor that are globally distributed in a wide range of geologic settings including shallow, estuarine environments like Belfast Bay, Maine.

Gas Hydrate Accumulation Related to Pockmarks and Faults in the Zhongjiannan Basin, South China Sea
Frontiers in Earth Science, 2022 The amplitude and coherence attributes of three-dimensional (3D) seismic data are used to confirm gas hydrate occurrence and to delineate its distribution in the Zhongjiannan basin, South China Sea.
