Summary: A catastrophic heatwave hit North America in 2021, and the mechanism behind it is still unclear. The study found that the occurrence of heatwaves in western North America is often associated with quasi-barotropic ridges (QBTRs). The frequency of QBTRs is influenced by large-scale forcing, with Arctic sea ice variations playing a significant role after 2000. The findings suggest that further loss of Arctic sea ice could lead to more severe heatwaves in western North America.

Summary: Understanding the hydro- and morphodynamics of the lower shoreface is crucial for coastal management and maintenance. The Dutch coast's shoreface is influenced by past evolution and present-day processes. The morphology varies along the coast due to coastal slope and superposition of ridges and ebb-tidal deltas. Field data and numerical modeling were used to study the lower shoreface, revealing variations in composition and morphology. Sand transport and sediment changes are important factors in the study. The results show different patterns of sand transport and trends in the shoreface morphology along the coast.

Summary: The study utilized high-resolution seismic data to conduct a detailed analysis of Quaternary sediments in the northern North Sea, revealing that the sediment deposition in the North Sea trough-mouth fan may have occurred later than previously thought. Additionally, evidence of sediment disturbance by ice-stream activity near the base of the Norwegian Channel was observed. A new age model proposed for the Quaternary sediments in the northern North Sea provides insights into glacial events and aids in reconstructing spatial and temporal patterns of sediment subsidence and fluid overpressure in the North Sea Basin.

Summary: This paper discusses the 3D architecture of the Sao Francisco delta in Brazil and the role played by GIA far-field effects in its construction, using a new dataset. The delta construction began around 8.4 thousand years ago and went through stages of normal regression and forced regression. The drop in relative sea level since the mid-Holocene, characteristic of GIA far-field regions, contributed to the increased resilience of the delta to ongoing sea-level rise. The antecedent topography strongly influenced the 3D architecture of the delta.

Summary: The avulsion frequency of coastal-plain rivers is primarily controlled by the elevation difference between channels and neighboring plains, as well as multiple factors such as wave and tidal processes, rates of sea-level change, and bathymetry of the receiving basin. This study analyzes the relationship between these downstream factors and avulsion frequency in 57 Holocene lowland river systems, finding that wave and tidal processes may have a modest influence and there is no consistent relationship with offshore bathymetric gradient or sea-level fluctuations. This suggests that upstream or intrabasinal factors may play a more important role.

Summary: This study investigated the regional source apportionments of NH4+ in the Northern China Plain (NCP). The results showed that NH4+ concentration was positively correlated with PM2.5 mass, indicating its contribution to haze formation. The nitrogen isotopic composition analysis revealed negative correlations between δN-15-NH4+, δN-15-NH3 and PM2.5 mass, with no significant differences among the cities studied. By analyzing air mass backward trajectories and quantifying contributions from potential sources, non-agricultural sources (fossil fuel related and NH3 slip) were identified as the dominant sources of haze in the NCP region. However, during extreme haze phase, the contribution of fossil fuel related source decreased while livestock breeding source increased. The importance of NH3 emissions from volatilization-related agricultural sources (especially livestock breeding) in urban cities of the NCP region was highlighted, even though non-agricultural sources were the foremost contributors.

Summary: This study presents a new mechanism of turbidity current transformation from depositional to erosive in the South China Sea, resulting in the development of seafloor channels due to the confinement by seamounts and bedrock highs. The confinement increased flow competency and allowed the turbidity currents to carry larger volumes of coarse sediment, impacting basin-scale depositional patterns. These findings highlight the importance of pre-established basin topography in sedimentation processes.

Summary: This study examines the breakup unconformities and rock record in the offshore NW Australia, finding that these unconformities are related to magma intrusion and continental crust breakup. The study supports the idea that the 'breakup unconformity' is not always a single stratigraphic surface marking the onset of seafloor spreading.

Summary: This study uses logistic models to identify growth trajectories and resource base for CO2 storage consistent with European targets. The results show that achieving these targets requires a significant increase in annual injection rates, but the current resource base is sufficient. Only in the case of significantly limited storage resources would mitigation plans be constrained.

Summary: This study examines the structure and growth of salt-detached strike-slip faults using a 3D seismic reflection dataset from the Outer Kwanza Basin offshore Angola. The findings suggest that these faults formed to accommodate variations in differential seaward translation and salt diapirism. The growth of the fault arrays occurred through tip propagation of isolated fault segments, with some segments linking during specific time periods. The results also highlight the scatter in the D-L scaling of strike-slip faults, reflecting the propagation, interaction, and linkage of individual fault segments.

Summary: This study investigates the temporal and spatial evolution of thin-skinned deformation on the Tarakan Basin in offshore eastern Indonesia using 3D seismic reflection data. The results reveal concave- and convex-into-the-basin normal faults on a basal mobile shale, with normal faulting and shale mobilization starting in the Middle Miocene. The growth faults and anticlines in the delta system are influenced by variations in sedimentary loading, mobile-shale flow, and the trend and dip of the base mobile-shale surface.

Summary: Salt tectonics is primarily driven by the movement of evaporites due to gravity gliding and differential loading. Understanding the complexities of salt basins is crucial, especially when carbonate and clastic rocks interbed with evaporitic strata. Using seismic reflection and borehole data, we analyze the formation and deformation of minibasins within the Zechstein Supergroup in the Devil's Hole Horst, UK. Our findings refine the depositional model for the Central North Sea and provide insights into syn-depositional salt flow in layered evaporitic sequences and its impact on petroleum plays.

Summary: In this study, we used seismic reflection, geochemical, and petrophysical data to investigate how the physical properties of oozes control slope failure and emplacement processes. We discovered potential slide surfaces within ooze successions, which is crucial for improved submarine geohazard assessment. Additionally, we found that tectonics, ocean current activity, and silica diagenesis can prime multiple slides on low-gradient slopes in tropical oceanic basins.

Summary: The Los Molles Formation in the Neuquen Basin of Argentina provides a rare opportunity to study syn-rift to post-rift stratigraphy. A field-based study in the Chachil Graben revealed the stratigraphic evolution of two deep-marine intraslope lobe complexes, which were built by different types of flows and exhibited differences in their characteristics. Petrographic analysis further showed that the lobe complexes are volcanic arc-sourced. The study also proposed a model for intraslope lobe complex development and highlighted the importance of flow behavior and transformation in understanding their hydrocarbon reservoir potential.

Summary: In this study, a model of the Late Jurassic rift physiography of the Froan Basin and Froya High is presented based on seismic reflection, well data, and reverse subsidence modelling. The results show that major footwall uplift during the Late Jurassic to Early Cretaceous caused the Froya High and the western margin of the central Froan Basin to be subaerially exposed, forming an intra-rift footwall island. Shallow marine areas to the east accumulated sediment supplied from the uplifted and partially eroded footwall, while the Trondelag Platform remained submerged throughout the rift episode.

Summary: Rift basins typically go through three main tectono-stratigraphic stages: pre-, syn- and post-rift. The syn-rift stage is characterized by the deposition of asymmetric growth strata wedges due to active normal faulting, while the subsequent post-rift stage is defined by long-wavelength subsidence driven by lithospheric cooling.

Summary: The spatial variation of the topological characteristics of normal fault networks at the rift-scale is investigated using 3D seismic reflection data from the northern North Sea. It is found that fault orientation varies spatially along the rift margin, with different dominant strikes in fault blocks adjacent to the graben compared to those farther from the graben. Two broad topological domains are identified within the fault network, which correlate with the sub-division of the rift margin into different structural domains. There is also a positive correlation between fault orientations and intensity, highlighting the relationship between fault geometry and topology.
