The Paleozoic Hydrocarbon System in the Gotland Basin (Central Baltic Sea) Leaks

Earth and Space Science, 2023
The Baltic Basin is known for its numerous Paleozoic hydrocarbon reservoirs. There is published evidence that hydrocarbons are leaking from the seafloor, however, little is known about the hydrocarbon migration pathways from Paleozoic source and ...

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

Exploring Antarctic Feedback Mechanisms Using Two‐Way Coupled Subglacial Hydrology and Ice Flow Modeling in the Siple Coast

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.

Pockmarks and fluid migration in the Estremadura Spur, Western Iberian Margin. [PDF]

, 2018
A field with more than 70 pockmarks in the Estremadura Spur outer shelf on the Western Iberia margin is the main focus of research of the PES project. High-resolution seismic reflection profiles and multibeam bathymetry allowed the characterization of ...

Gas Seepage-Induced Features in the Hypoxic/Anoxic, Shallow, Marine Environment of Amfilochia Bay, Amvrakikos Gulf (Western Greece)

Geosciences, 2021
Amfilochia Bay (Eastern Amvrakikos Gulf, Western Greece), a complex marine area affected by tectonism, was investigated for seabed seepage manifestations and for possible inter-relationships between shallow gas accumulations and hypoxia. For this purpose,

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 ...

Giant lacustrine pockmarks with subaqueous groundwater discharge and subsurface sediment mobilization [PDF]

, 2015
Subsurface fluid flow in oceans and lakes affects bathymetric morphology, sediment distribution, and water composition. We present newly discovered giant lacustrine pockmarks in Lake Neuchatel (up to 160m diameter and 30m deep) that rank among the ...

Tracing methane sources in shallow waters of the North Sea: Biogenic signatures and hydrocarbon transport near abandoned wells

Limnology and Oceanography, Volume 71, Issue 7, July 2026.
Abstract Numerous abandoned wells in the North Sea may provide gas, particularly methane (CH4), migration pathways by penetrating shallow, biogenic gas accumulations. However, related sampling campaigns have been largely contradictory and lack a substantial database. Research cruise MSM98 targeted the abandoned wells B18‐1, DOK 1‐X, B11‐2, THOR and D‐1

Quantifying Thermo‐Fluid‐Chemical Coupling: Advection Governs Multi‐Phase Zonation and Self‐Sealing in a Hydrate‐Cold Seep System

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 7, July 2026.
Abstract Deep fluid advection fundamentally governs the thermal‐fluid‐chemical evolution and distribution of hydrate‐cold seep systems. However, coupled relationships between deep fluid and shallow multiphase dynamics remain inadequately constrained.

Mega‐Depressions on the Cocos Ridge: Links Between Volcanism, Faults, Hydrothermal Circulation, and Dissolution

Geochemistry, Geophysics, Geosystems, 2022
High‐resolution bathymetry and three‐dimensional seismic data along the Cocos Ridge reveal a 245 km2 field of ∼1–4 km in diameter seafloor depressions. The seafloor depressions are part of a two‐tiered honeycomb pattern.
