How Does Plastic Litter Accumulate in Submarine Canyons?

Geophysical Research Letters, Volume 51, Issue 18, 28 September 2024.
Abstract Manned submersible dives in the northwest South China Sea encountered substantial amounts of plastic litter accumulated at the base of scours along the floor of a submarine canyon, which may associate with the depositional behaviors of turbidity currents.

Submarine geohazards on the northwestern continental margin of the South China Sea and their mechanism

Geological Journal, Volume 59, Issue 6, Page 1759-1773, June 2024.
In this paper, we have identified two types of submarine geohazards: direct geohazards and indirect geohazards on the northwestern continental slope and Xisha Uplift of the South China Sea. We conclude the formation of submarine geohazards is constrained by multiple factors, such as tectonic activity, sediment supply and relative changes in sea level ...

Methanogenic Archaea as Catalysts for Magnetite Formation in Iron‐Rich Marine Sediments

Journal of Geophysical Research: Solid Earth, Volume 129, Issue 6, June 2024.
Abstract Fine‐grained authigenic magnetite has been recognized increasingly in iron‐rich marine environments affected by methane seepage and is a major sedimentary magnetization source. However, it is unknown whether this magnetite forms via microbial or abiotic processes.

Architecture and evolution of shelf‐margin clinoforms developed in a back‐arc tectonic setting: Insights from quantitative analysis on the south‐west shelf margin of the Ulleung Basin

Basin Research, Volume 36, Issue 2, March–April 2024.
Stratigraphic chart for the Ulleung Basin shows seismic units, eustatic changes, calculated sediment supply and measured shelf‐margin aggradation, with major tectonic events. Brief depositional models of three different seismic units imply the transitional changes from the opening to the closing in the ‘old’ back‐arc Ulleung Basin. Abstract Geophysical

Sedimentological Characteristics of the Coal Seams of Yacheng Formation in Qiongdongnan Basin, China

Energy Exploration & Exploitation, 2009
Yacheng Formation has been divided into one cycle sequence of ultra long-period, three cylce sequences of long-period and 12 cycle sequences of intermediate period based on data from comprehensive drilling cores, logging, the seismic survey and former studies.

A Critical Appraisal of the Sensitivity of Detrital Zircon U–Pb Provenance Data to Constrain Drainage Network Evolution in Southeast Tibet

Journal of Geophysical Research: Earth Surface, Volume 129, Issue 2, February 2024.
Abstract Provenance tools, particularly detrital zircon U–Pb analysis, have been widely employed to test drainage network evolution in southeast Tibet and its linkage with the growth of the Tibetan Plateau. Numerous provenance studies have been conducted on the sediments in the paleo‐Yangtze and paleo‐Red River drainage basins.

Unveiling deep-sea benthic biodiversity in the northern South China Sea through environmental DNA metabarcoding

Frontiers in Marine Science
The northern South China Sea hosts highly heterogeneous deep-sea habitats, dotted with numerous active cold seeps and associated chemosynthetic ecosystems, while the Qiongdongnan Basin represents one of the most important natural gas hydrate accumulation
