Summary: This study investigates the source-to-sink processes of terrigenous sediment in the northeastern South China Sea. The results show that sediment is primarily derived from Taiwan, and sea level changes play a significant role in sedimentation. The intrusion of the Kuroshio current and weakening of the East Asian monsoon also affect sedimentation.

Summary: The study utilized high-resolution bathymetric and seismic data to investigate the morphology of a submarine canyon (Taiwan Canyon) in the northeast South China Sea, revealing asymmetrical banks and sediment wave fields. Different sources of turbidity currents entering the canyon led to distinct depositional features, contributing to a better understanding of submarine canyon evolution and formation.

Summary: The intrusion of the Kuroshio has an impact on the abundance and composition of microplastics in the South China Sea, but it is not the dominant influencing factor. The effects of the Kuroshio intrusion appear to be a combination of dilution and biogeochemical influences. Further research is needed to understand the comprehensive impact of Kuroshio intrusion on microplastics fate in the Western Boundary Current system.

Summary: Recent mooring observations on the continental slope of the Dongsha Island in the northeastern South China Sea demonstrate the generation of along-slope bottom currents due to the dissipation of obliquely incident internal tides. New mooring data collected on the south side of the island confirms the ability of the previous theory in estimating the along-slope current. Strong near-bottom energy dissipation and a southwestward along-slope current are observed, with the maximum velocity exceeding 6 cm/s.

Summary: This study reveals the presence of slope intrusion eddies in the slope region of the northern South China Sea, which have significant horizontal asymmetry and induce cross-slope heat and salt transport. The horizontal asymmetry of these eddies is mainly caused by eddy-current nonlinear effect in the Dongsha Islands and topographic beta effect in the Xisha Islands.

Summary: This study analyzed the morphology and sediment characteristics of the unvegetated intertidal flats along the Jiangsu Coast in China, identifying differences in sediment patterns between the eroding northern part and the accreting southern part. The north coast showed alternating very fine and coarse sediment, while the south coast displayed gradual coarsening of bed surface sediment and flattening of beach slopes to the south. Waves were found to have only a secondary importance in sediment dynamics on the tidal flats.

Summary: Tectonically active coasts are characterized by multiple marine terraces formed by a combination of wave erosion, tectonic uplift, and sea-level oscillations. Our study of the marine terraces along the western coast of South America revealed a median elevation of 30.1 m, suggesting a median uplift rate of 0.22 m kyr(-1) over the past approximately 125 kyr. The patterns of terrace elevation and uplift rate exhibit different structures along the coast, with long-wavelength deformation possibly being controlled by deep-seated processes like subduction, while short-wavelength deformation may be associated with crustal faulting.

Summary: This study utilized satellite-tracked Lagrangian drifters to investigate the transport pathways of near-surface water around the Luzon Strait, focusing on the intrusion of Pacific water into the South China Sea. Results showed that, apart from the Kuroshio water, other Pacific water can also intrude into the SCS through different mechanisms, with a smaller but significant contribution over multiple years and individual events. Through simulated trajectories and case studies, the study also highlighted the importance of various factors, such as Ekman drift and eddy-Kuroshio interaction, in the intrusion of Pacific water and its spreading in the SCS.

Summary: The levels of natural radionuclides' radioactivity at the coast of Brunei Darussalam were evaluated, along with their dose rates, using gamma-ray spectrometry on sediment samples. The average activity concentrations of 226Ra, 232Th, and 40K in berm sediments were found to be 10.07 +/- 1.02 Bq/kg, below the minimum detectable activity, and 21.44 +/- 1.23 Bq/kg, respectively. For intertidal sediments, they were 7.01 +/- 0.87, 1.67 +/- 0.15, and 4.99 +/- 0.42 Bq/kg, respectively. It was also found that 40K is the main source of radiation in coastal sediments. Moreover, the study investigated the difference in radioactivity levels between berm and intertidal sediments collected at the same location.

Summary: Intertidal flats are important for their socio-economic and ecological value, but the relationship between alongshore slope and sediment grain size is unexpectedly opposite along the Jiangsu Coast. The hypothesis of alongshore hydrodynamic gradient being the cause was tested through numerical model simulations, and it was found that sediment provenance is the key factor explaining the inconsistency.

Summary: The study investigated the distribution, congener patterns, possible sources, and ecological risks of polybrominated diphenyl ethers (PBDEs) in the surface sediments of 20 fishing ports along the coast of Bohai Sea. The results showed that BDE-209 was the dominant congener and high concentrations of PBDEs were found near Liaohe River, Haihe River, manufacturing plants of BFRs near Laizhou Bay, and tipping areas of marine garbage.

Summary: Deep-water channels exhibit different morphologies and stratigraphies due to density contrast between flow and ambient fluid, with turbidite channels favoring lateral migration and contourite channels favoring thalweg deposition. Channels formed during greenhouse climates show low morphological variations, while icehouse channels exhibit high variations, suggesting weak global correlation of channel-population densities with warming greenhouse climates.

Summary: The petroleum resource assessment obtained from laboratory tests on old core samples tends to underestimate the in situ resources. This study investigates the hydrocarbon loss and restoration by comparing preserved and exposed core samples. It is found that previous studies have severely underestimated the in situ hydrocarbon potential due to factors such as sample crushing and crucible waiting. A new restoration model is proposed to compensate for these losses.

Summary: Quartz cement is an important authigenic mineral in the tight sandstones of the Shaximiao Formation in the Sichuan Basin. This study analyzed the silicon sources of the quartz cement using mineralogical, fluid inclusion, and geochemical data. The results showed that smectite alteration and dissolution of aluminosilicate minerals were the primary sources of silicon for quartz cementation. Contributions from volcanic material hydrolysis and pressure solution were relatively minor. The presence of chlorite films inhibited the development of quartz overgrowths and had minimal impact on reservoir quality.

Summary: This study investigates 13 submarine seamounts in the southern Andaman volcanic arc and observes evidence of hydrothermal activity in one of the seamounts. The evidence includes plumes rich in dissolved gases, live chemosymbiotic organisms, and the deposition of neoforming minerals. These observations suggest the development of a new hydrothermal field in the least explored Andaman Sea.

Summary: This study employs an integrated depositional and sequence stratigraphic approach to assess the control of diagenesis on reservoir porosity of a hybrid-energy delta system. The study focuses on the Barik Formation in the Haushi-Huqf region of Central Oman, which represents a highstand system tract of a hybrid-energy delta. The assessments reveal that the reservoir porosity is controlled by various degrees of diagenetic processes, including mechanically infiltrated clays and kaolinitization of silicate grains.

Summary: Oilfield brines are a significant alternative lithium resource. This study investigates the metallogenic characteristics and enrichment process of oilfield brines from the Jianghan Basin, central China using chemical and multi-isotope data. The results suggest that lithium enrichment in these brines is the result of interaction with clastic host rocks and dilution by meteoric water.

Summary: Due to the lack of deep wells in the broader region, studying mud volcanic deposits can improve the geological understanding of the Mediterranean Ridge. In this study, biostratigraphic and geochemical analyses were performed on mud breccia deposits from five Mud Volcanoes in the central MR. The results indicate the origin of these deposits and provide insights into the source rock potential. Seismic data is also used to determine the distribution of major lithostratigraphic formations.
