Summary: Intra-continental wrenching is often associated with crustal faulting and fragmentation. The position of the Falkland Islands Microplate before the breakup of Gondwana is still uncertain. This study integrates gravity and seismic reflection data to provide insights into the tectono-stratigraphic architecture and evolution of the Falkland Islands Microplate.

Summary: This study focuses on the Late Devonian Illinois Basin and establishes a basin evolution model through correlation analysis and high-resolution chemostratigraphic profiles. The study reveals three phases of NAS deposition and identifies four anoxic pulses during the NAS deposition. Correlation analysis with other basin data also links some of the anoxic pulses to key biotic crises in the Late Devonian.

Summary: A new inter-basin teleconnection analysis method is proposed to investigate the connection among global oceans comprehensively. The Australia Boundary Current Dipole (ABCD) is discovered, which shows a strong negative correlation between sea surface temperature (SST) along Leeuwin Current (LC) and East Australia Current (EAC). This new inter-basin air-sea coupled mode exhibits remarkable interannual variability. The anomalies in SST are mainly generated by anomalous Australia High inducing opposite surface winds along the coast, which in turn reinforce the wind anomalies by affecting the overlying atmosphere and regional pressure anomalies. The meridional ocean advections control the anomalous SST, indicating the essential role of coastal Bjerknes feedback. The kinetic energy analysis further demonstrates that ABCD represents the reverse variation pattern of LC and EAC.

Summary: This study investigates the seasonal variability of the carbonate system in the eastern Mediterranean Sea, specifically focusing on the North Western Levantine Basin. The findings show that changes in A(T) and C-T in the NWLB are unique due to the interplay between evaporation and autotrophic processes, impacting seawater pCO(2)(SW). The study also highlights significant ocean acidification and a decrease in oceanic surface pH(T)(25) driven by increased atmospheric CO2 and unexplained temporal changes in surface A(T) content.

Summary: This study provides a comprehensive analysis of pre-salt basement fault trends in the Southern North Sea Basin, revealing a dominant NW-SE trend. The similarities in basement fault trends in the SW sub-basins suggest a common origin, while the presence of different trends in the NE sub-basins may indicate structural inheritance from smaller pre-Caledonian terranes.

Summary: The oil fields in the North Alaska Super Basin have produced a significant amount of oil, with large reserves still remaining untapped. Advances in technology have led to the discovery of new oil fields like Willow and Pikka, with clear interpretations of the oil sources for each field.

Summary: Biomarker data from a core drilled in the Qaidam Basin in western China reveal intermittent connection between the basin and the Proto-Paratethys Sea via the Tarim Basin during the middle Eocene, followed by a hydrographically isolated non-marine environment in the Late Eocene.

Summary: The Cretaceous is an important exploration target layer in the eastern depression of the North Yellow Sea basin, with significant oil and gas potential. The main rock types of the Cretaceous reservoir in this area are lithic arkose, feldspar lithic sandstone, feldspar sandstone, and a small amount of lithic sandstone. The reservoir has low porosity and low permeability, with secondary pores dominated by dissolution pores and fractures. The petrophysical characteristics of the reservoir are mainly influenced by provenance properties, sedimentation, diagenesis, and tectonism.

Summary: The study uses geochemical data from the Panama Basin and the Northern Volcanic Province of Colombia to show that the processes of a subducted ocean basin can influence the compositions of continental arc volcanoes. Specifically, variations in sediment compositions are found to impact the compositions of arc magmas.

Summary: The study of the Stord Basin in the northern North Sea reveals the complexities of rift kinematics and strain migration between two rift episodes. The control of pre-existing structures on basin-bounding fault systems and the migration of rift axes during different phases highlight the heterogeneous nature of rift evolution within a single basin.

Summary: Inner Asia underwent dramatic changes in sea-land distributions and paleoenvironment in the Cenozoic, resulting in the retreat of the proto-Paratethys and the formation of the largest mid-latitude dryland in Central Asia. The Alay Valley, which connected the Tarim and Tajik Basins, experienced a major change in altitude and witnessed the final seawater retreat at 37.8 Ma. The timing and process of this retreat are important for understanding tectonics, surface processes, and climate.

Summary: This study investigates the evaluation of pedotransfer functions (PTFs) using legacy data in new regions, particularly focusing on the challenges arising from non-random sampling and clustering at multiple scales. By evaluating soil moisture content predictions at different spatial scales, it is found that PTFs calibrated with tropical domain data generally perform better, but not all of them. The study also reveals that PTFs capturing regional-scale variation may not necessarily be useful for predicting variation within a profile, considering the spatial clustering of the data.

Summary: Two competing hypotheses, glacioeustasy and groundwater aquifer eustasy, were evaluated for their impact on global sea-level changes during the Late Triassic. Sedimentary noise modeling and principal component analysis were used to reconstruct lake level fluctuations, revealing a link between million-year scale lake-level variations and astronomical forcing. This study highlights the importance of high-resolution, objective reconstructions of sea- and lake-levels for further testing these hypotheses under warm conditions.

Summary: The study quantified the meridional transport of North Atlantic deep water (NADW) on both sides of the Mid-Atlantic Ridge (MAR) and found that the eastern basin contributes a significant portion of the southward transport. Observing NADW transport variations on the eastern side of the MAR is crucial for monitoring the strength of the Atlantic Meridional Overturning Circulation.
