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.

Combining morphological and molecular data to study past foraminiferal communities from a temperate coastal sediment core

Boreas, Volume 55, Issue 1, Page 198-215, January 2026.
This paper presents the results of a dual approach for assessing fossil benthic foraminiferal communities using both traditional morphology‐based analyses and sedimentary ancient DNA (sedaDNA) metabarcoding. The main objectives are to test the feasibility of sedaDNA analyses to assess foraminiferal biodiversity in temperate shelf sediments (Le Croisic,

Protracted intercontinental aridification preserved within the early Late Cretaceous strata of the Eastern Gobi Basin, Mongolia

Sedimentology, Volume 73, Issue 1, Page 147-185, January 2026.
ABSTRACT Mongolia's Eastern and Western Gobi Basins preserve a globally significant record of Cretaceous terrestrial vertebrates, yet their biostratigraphic correlations are complicated by a complex geological history. The Eastern Gobi Basin, a northeast‐southwest trending fault‐bounded rift system, includes several minor sub‐basins with distinct ...

Methane-flow system within the Nyegga pockmark field, offshore mid-Norway

Frontiers in Earth Science, 2023
We investigated fluid seepage within the Nyegga pockmark field (600–900 m water depths) off mid-Norway from Remotely Operated Vehicle dives at the so-called CNE sites (CNE01 to CNE17).

Influence of Glaciological Structures on the Spatial Distribution of Cryoconite Holes, Northern Victoria Land, East Antarctica

Journal of Geophysical Research: Earth Surface, Volume 130, Issue 12, December 2025.
Abstract Three blue‐ice areas in the upper reaches of Rennick Glacier, East Antarctica, are investigated using satellite remote sensing to assess the influence of meso‐ to large‐scale glaciological structures on cryoconite hole distributions. In total, 15,299 cryoconite holes and 1 600 structures were geospatially analyzed, which indicate that ...

Experimental seabed disturbance effects on Chatham Rise deep‐sea meiofaunal communities, Southwest Pacific

New Zealand Journal of Marine and Freshwater Research, Volume 59, Issue 5, Page 1388-1421, December 2025.
ABSTRACT Growing global demand for deep‐sea resources may lead to increased pressure on benthic ecosystems. Here we examined changes in meiofaunal communities following an in situ physical disturbance experiment. A significant change in meiofaunal community structure in surface (0‐1 cm) and subsurface (1‐5 cm) sediments was observed immediately ...

Multi-parameter coupling effects on plume morphology and pockmark development induced by submarine shallow gas leakage

Frontiers in Marine Science
Plumes and pockmarks are formed when shallow gas breaches the seabed and infiltrates into ocean currents, disrupting the original ecological environment and affecting biological habitats and migration behaviors.
