Summary: The South China Sea is a major hotspot for plastic discharge and accumulation of microplastics. Microplastic abundance is higher in coastal areas compared to basin areas, while sediment abundance shows less variation. Basin-scale circulation and regional currents play an important role in the transport of microplastics.

Summary: The evolution of the Proto-South China Sea is influenced by both its paleogeographic location and the history of its oceanic crust, with significant changes in tectonic properties from the Triassic to the mid-Late Cretaceous ultimately shaping the current structure of the South China Sea.

Summary: This study investigates contourite drifts in the southern South China Sea for the first time, identifying the common occurrence of a lesser-known type: the fault-controlled drift. Six fault-controlled drifts are generated in the study area, divided into two major types based on their shapes, locations, and relative faulting movements. The depth of the South China Sea Deep Water, shallower in the southern region compared to the northern part, tentatively suggests upwelling and impacts on the meridional overturning circulation. Additional research is needed to further understand the effects of faulting on sedimentary stacking patterns, geometries, and evolution of contourite drifts in different tectonic settings.

Summary: Mega pockmarks were identified in the Reed Basin of the South China Sea, and they are formed by seafloor gas explosions related to buried gas deposits. These findings have important implications for the exploration and research of deep-sea gas resources.

Summary: This study investigated the concentrations and distribution of dissolved organic carbon (DOC) in the South China Sea and the western North Pacific. Laboratory experiments were conducted to determine the microbiological respiration of DOC. The findings revealed that DOC concentrations in the South China Sea varied greatly and were influenced by multiple factors. Physical mixing played a significant role in the distribution of mesopelagic DOC in the northern South China Sea basin.

Summary: Ammonium dynamics in the oligotrophic South China Sea were found to be influenced by factors such as Kuroshio intrusion, leading to considerable variation in NH4+ concentrations between 2014 and 2016. Stations affected by the Kuroshio showed higher NH4+ concentrations and lower NO3- inventories. Two patterns in vertical NH4+ distributions were observed, with profiles showing subsurface NH4+ maximum and profiles with generally uniform NH4+ concentrations.

Summary: By investigating the tectonic histories of continental marginal basins in the central-southern South China Sea, it was found that different types of basins have different conditions for hydrocarbon accumulation, mainly controlled by tectonic events. Over time, these basins generally progressed through three developmental stages during the Cenozoic, with varying reservoir characteristics and filling patterns, resulting in different hydrocarbon resource features.

Summary: Based on previous research on Mesozoic igneous rocks and tectonic environments, this study investigates the geophysical parameters, strata, and seismic facies characteristics of the northern South China Sea and southern East China Sea (NSCS-SECS). The tectonic evolution of the SECS since the Jurassic is re-evaluated using balanced profile evolution analysis. Additionally, the burial history and well simulation in the SECS are analyzed using well, seismic, and source rock data. The findings provide insights into Mesozoic oil and gas exploration in the NSCS-SECS.

Summary: The study analyzed the structural units, tectonic features, and geodynamics of the Nan'an Basin based on newly acquired seismic data. The findings suggest that the basin is a northeast-southwest oriented rift basin, rather than a pull-apart basin induced by strike-slip faults. It provides evidence for the importance of regional strike-slips and orthogonal displacement during basin development and deformation. Rating: 8/10.

Summary: This study presents the first biogeochemical data set from growing ice in the Atlantic Antarctic marginal ice zone during winter 2019, providing evidence that winter sea ice is biogeochemically active and acts as a reservoir of concentrated nutrients during the ice growth season.

Summary: Sea surface temperature is an important parameter in marine research, and accurately predicting it is crucial for addressing climate change, marine ecological protection, and marine economic development. This study investigates the prediction performance of ConvLSTM and ST-ConvLSTM models with different input lengths, prediction lengths, and hidden sizes. The results show that input length and prediction length have impacts on the prediction performance, and the setting of hidden size significantly influences the prediction ability. Careful consideration is needed when determining these parameters to achieve optimal performance.

Summary: Based on a reevaluation of various data, the author proposes that the Yangtze and Cathaysia blocks in South China did not merge until the early Paleozoic. Before that, they were located at different parts of Gondwana. This implies that the orogeny in South China could be attributed to two distinct events: the collision of Cathaysia/Australia with India in the late Ediacaran to early Cambrian, and the amalgamation of Cathaysia with Yangtze in the Late Ordovician.

Summary: This study evaluates the response of shale fracturing and gas loss to differential tectonic reworking using Lower Silurian shale in the Upper Yangtze Block. The Meso-Cenozoic uplift process was reconstructed, and the pressure evolution and shale gas content variation were quantified. The results showed that deformation increases fracture development and reduces the sealing capacity of the shale, while uplift amplitude is a major controlling factor. The maximum burial depth affects shale gas preservation during uplift. Differential enrichment of Lower Silurian shale gas is attributed to the differences in slip deformation, tectonic uplift amplitude, and maximum burial depth.

Summary: The study reveals the periodic evolution and characteristics of Palaeogene tectonic activity in the deep-water area of the Qiongdongnan Basin. It identifies the regional angular unconformity and periodic fault activity, discussing sedimentary paleogeomorphologic background and evolution through periodic rifting. The findings show three separate rifting phases and changes in paleo-geomorphology margin and subsidence center, which are important for petroleum exploration in marine basins.

Summary: Surface seawater carbon dioxide partial pressure (pCO(2)) in the south-central North Sea was biologically controlled, with winter trends showing positive biogeochemical effects. The sea-air CO2 flux in the study area changed significantly during the investigation period, indicating a shift in the carbon balance in the region.
