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 analyzes bottom currents within 5 meters above the seafloor in the South China Sea using mooring observations. The results show that bottom currents are dominated by currents induced by internal tides and internal solitary waves. The velocity amplitudes of these currents can reach up to 50-90 cm/s. The study also finds that the background bottom current is strongest in winter and weakest in summer and autumn, which is closely related to the behavior of mesoscale eddies.

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: We analyzed picoeukaryotes during the Luzon winter bloom using remote sensing, flow cytometry, and high throughput sequencing. The study found a seasonal increase in phytoplankton in the study area during winter, with photosynthetic picoeukaryotes being the main contributors to the total phytoplankton biomass. The distribution of different picoeukaryote communities varied, with auto- and mixotrophic picoalgae mainly in the upper layers and heterotrophic flagellates and parasites dominating the deep layers. The growth of photosynthetic picoeukaryotes was stimulated by Kuroshio-induced upwelling.

Summary: Based on observation and remote sensing data, this paper explores the formation mechanism and evolution law of winter counter-wind currents in the Jiazi sea area of the northeastern South China Sea. The results show that the counter-wind current occurs only in certain time periods and is formed due to the concerted action of wind stress, the baroclinic effect, and geostrophic effect. The appearance of cold water masses in the northwest of 116 degrees E sea area and warm water masses in the southeast of the South China Sea is the key to the formation of both the two different current systems with 116 degrees E as the boundary and the winter counter-wind flow.

Summary: This study investigated the vertical distribution of species richness, abundance, and biomass of planktonic ostracods in the northeastern and central South China Sea. The results showed that the distribution of planktonic ostracods was associated with chlorophyll a concentration and sampling depth, with the highest concentration observed in the mesopelagic zone. The high abundance and species richness in the northeastern South China Sea may be influenced by the Kuroshio intrusion and eddies.

Summary: Moored current observations in the northwestern South China Sea captured two events of near-inertial waves induced by tropical cyclones, which propagated to the seafloor from the mixed layer base at different speeds related to the background vorticity. Bottom NIWs showed different frequency shifts when the observation site was located outside/inside an anticyclonic eddy, and had high vertical shear, potentially playing an important role in deep mixing in the abyssal ocean.

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: 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 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.
