Thermogenic methane injection via bubble transport into the upper Arctic Ocean from the hydrate-charged Vestnesa Ridge, Svalbard [PDF]

open access: yes, 2014
We use new gas-hydrate geochemistry analyses, echosounder data, and three-dimensional P-Cable seismic data to study a gas-hydrate and free-gas system in 1200 m water depth at the Vestnesa Ridge offshore NW Svalbard.

Orientation of Microfeatures on Europa

open access: yesJournal of Geophysical Research: Planets, Volume 130, Issue 11, November 2025.
Abstract Microfeatures, including pits, spots, domes, hybrids, and microchaos, are abundant features on the surface of Europa. A better characterization of the microfeature morphology can help us understand their formation and Europa's surface evolution.

The space‐age hotel

open access: yesAmerican Ethnologist, Volume 52, Issue 4, Page 446-458, November 2025.
Abstract For years the decrepit Hotel Lunik in Eisenhüttenstadt, Germany, a city founded in 1950 as a model of socialist urbanism, has been widely understood as “a trace of capitalism.” Once a central landmark, Lunik was sold to a real estate speculator in 2006 and left to decay.

Characterizing an Incipient Fault System: Insights From the Morphometric Analysis of the North‐South Faults (Alboran Sea)

open access: yesTectonics, Volume 44, Issue 10, October 2025.
Abstract Investigating the dynamic evolution of active fault systems is fundamental for deciphering regional tectonics and assessing seismic risk, particularly in offshore regions where direct observation is challenging. Our ultra‐high‐resolution bathymetric study of the North‐South Faults (NSF) documents an incipient and dynamically evolving left ...

Metagenomic and geochemical characterization of pockmarked sediments overlaying the Troll petroleum reservoir in the North Sea

open access: yesBMC Microbiology, 2012
Background Pockmarks (depressions in the seabed) have been discovered throughout the world’s oceans and are often related to hydrocarbon seepage. Although high concentrations of pockmarks are present in the seabed overlaying the Troll oil and gas ...

Fate of Underground Brine Resources in Beach and Neritic Zones in Shallow Aquifers Driven by Salt Pumps

open access: yesWater Resources Research, Volume 61, Issue 10, October 2025.
Abstract Underground brine in beach and neritic zones (UBBN), widely distributed on muddy coasts in arid coastal regions, undergoes dynamic salt cycling driven by a “salt pump” system, composed of hydraulic gradients, salinity gradients, and tidal forces.

The great escape: An intra‐Messinian gas system in the eastern Mediterranean

open access: yesGeophysical Research Letters, 2012
This study explores, for the first time, the response of the Mediterranean seafloor to desiccation and its affect on climate during the Messinian lowstand.

Chemosynthetic Organic Matter Reveals a Protracted Episode of Past Methane Seepage Activities at a Newly Discovered Cold Seep Site (Mannar Basin) Off the East Coast of India

open access: yesGeophysical Research Letters, Volume 52, Issue 17, 16 September 2025.
Abstract Here, we present organic geochemical evidence of past methane‐seepage events in a sediment core retrieved from a recently discovered methane cold‐seep site off Mannar Basin, east coast of India. The significant negative C‐isotope excursion of organic matter (δ13CTOC) in the seep core compared to a reference non‐seep core suggests a substantial
