Summary: This study reveals the impact of ocean wave-wave interactions on the seismic wavefield generated offshore West of Ireland in the Northeast Atlantic. The variations observed are closely correlated with changing patterns in secondary microseism generation areas, potentially influenced by the North Atlantic Oscillation.

Summary: Plumes are regions of hotter material rising through Earth's mantle, affecting the lithosphere. The Iceland plume in the NE Atlantic played a role in the breakup between Europe and Laurentia. This study provides a 3D density model showing the impact of the Iceland plume on the NE Atlantic crust and uppermost mantle.

Summary: The study investigates the crustal architecture, tectonic history, and rift-related magmatism along the western Porcupine Bank margin. Significant margin-parallel and margin-perpendicular structural variations are observed, mapping out the distribution of different crustal domains in the region.

Summary: The study found that in the waters off the northwest Iberian Peninsula, the concentration of cobalamin B12 is very low, mainly concentrated in the subsurface Eastern North Atlantic Central Water. B12 concentration is not a predictive factor for phytoplankton biomass or production, while prokaryote production is the best predictor for primary production. Eukaryote community composition is more closely correlated with prokaryote community composition, indicating that biotic interactions play a significant role in regulating microbial communities.

Summary: The SONTE-China network in China measures pixel- and multilayer-based soil moisture and temperature, covering dry and wet zones. It validates soil moisture products and provides basic data for weather forecasting, flood forecasting, agricultural drought monitoring, and water resource management.

Summary: During the first billion years of Earth's history, geological events were crucial in shaping Earth into a habitable planet. The North China Craton preserves the oldest rocks and minerals in China, providing insights into early Earth processes.

Summary: The connection between the North Tropical Atlantic (NTA) sea surface temperature (SST) anomalies and El Nino-Southern Oscillation (ENSO) events varies considerably over multidecadal timescales and is mainly controlled by the multidecadal variability of the North Atlantic Oscillation (NAO). During the positive phase of the NAO, the NTA impact on ENSO is amplified due to strengthening of precipitation over the equatorial Atlantic and enhancement of the persistence of NTA SST anomalies.

Summary: The study shows that sea ice-air interactions are crucial for multidecadal climate variability in both the Arctic and North Atlantic. By amplifying multidecadal variations in sea-ice cover, sea surface temperatures, and surface air temperature, sea ice-air interactions mainly affect the Atlantic Meridional Overturning Circulation through changes in surface fluxes.

Summary: The formation and tectonothermal overprinting of the Meso-Neoarchean metagranitoids in the Wuhe complex of the southeastern margin of the North China Craton are not well understood. Understanding the Phanerozoic overprinting in Archean complexes is important for comprehending the evolution of the North China Craton. The rocks in the Wuhe complex were affected by multiple tectono-magmatic-metamorphic thermal events, and the presence of inherited zircons suggests the underthrusting of the Yangtze Craton beneath the North China Craton during the Triassic.

Summary: This study presents 1-D and 3-D shear wave velocity models of the oceanic crust and uppermost mantle below the Deep Ocean Test Array area in the eastern North-Atlantic Ocean. The models are inferred from the dispersion of surface waves recorded on ocean bottom seismometers. The 1-D model shows the velocity distribution of sediment layer and oceanic crust, while the 3-D model reveals the horizontally layered structure of the crust with oscillations indicating changes in mantle upwelling and magma supply rate.

Summary: The geological structure of the western region of Islas Marias Archipelago is complex, with the Rivera plate dipping at 8 to 9 degrees in this area. Additionally, five sedimentary basins and active normal faults were found at the edges of tectonic structures in the area. The beginning of active subduction of the Rivera plate beneath North America is marked by the Sierra de Cleofas, with a low-velocity layer associated with Rivera Plate subduction observed beneath the Jalisco Block.

Summary: The petrogenesis of tonalite-trondhjemite-granodiorite (TTG) suites in the Zhongtiao Mountains of the North China Craton provides important clues for understanding the formation and evolution of continental crust. Through the investigation of two episodes of TTG gneisses in the Neoarchean period, it is revealed that these gneisses share similar geochemical features with Archean TTGs and Phanerozoic high-SiO2 adakites, indicating a partial melting of mafic rocks. The different characteristics of these TTGs suggest different geodynamic processes, possibly related to subduction and thickened lower crust.

Summary: This study on a tonalite-trondhjemite-granodiorite (TTG)-granites-quartz monzonite assemblage in the northeastern North China Craton provides insights into the growth and evolution of the early continental crust. Geochemical and geochronological analysis reveals the residues of garnet-amphibolite-to-eclogite facies in the TTGs, indicating a continental arc setting for their formation. The involvement of various crustal materials from different geological eras suggests a complex crustal evolution process.

Summary: The Jurassic granitoids in the Liaodong Peninsula show multi-stage magmatism with specific geochemical characteristics for the Early to Middle Jurassic granitoids originating from partial melting of the basaltic lower crust, and the Late Jurassic two-mica granitoids originating from partial melting of reworked ancient crustal materials. This suggests a complex crustal evolution history related to westward subduction of the Paleo-Pacific plate.
