Summary: Despite decades of research, significant gaps in our understanding of the oceanic cycling of neodymium (Nd) and rare earth elements (REEs) remain. Observations show that dissolved Nd concentration typically increases with depth, while Nd isotopes reflect conservative water mass mixing in the intermediate and deep ocean, known as the Nd paradox. This study in the South Atlantic provides detailed insights into the spatial controls on ocean geochemistry and the processes influencing Nd isotopic compositions.

Summary: Neodymium isotopes have been used to trace water mass source in the ocean, but the cycling of Nd is not fully understood. This study investigates the potential boundary processes near the seawater-sediment interface in Antarctica, showing the occurrence of a process similar to boundary exchange in porewaters. The study suggests that partial dissolution of radiogenic detrital particles and re-scavenging play a role in modifying the Nd isotopic ratios in porewaters. Benthic flux is found to be lower on the Antarctic margin compared to other studies, and it slightly increases along the Antarctic Peninsula due to organic matter degradation.

Summary: The isotopic composition of neodymium in seawater is an important tracer for investigating water mass provenance and past variations in ocean circulation. However, the available dataset for the Mediterranean Sea is limited, hindering our understanding of neodymium cycling in the basin. This study presents new neodymium isotopic data from 24 depth profiles in the Mediterranean Sea, providing insights into the relationship between dissolved neodymium isotopes and major water masses. The results suggest a zonal and depth gradient in neodymium isotopes, reflecting the basin's large-scale circulation.

Summary: An online approach for compound specific stable isotope analysis of bromochlorinated compounds was developed in this study using gas chromatography coupled to quadrupole mass spectrometry. Stable chlorine and bromine isotope ratios were simultaneously determined based on the mass spectral data of target compounds. The method showed good precision and reproducibility under optimized instrumental conditions.

Summary: The study shows that labile iron phases in riverine suspended particulate matter play a significant role in transporting rare earth elements and are derived from sedimentary rock erosion. Environmental changes in the Arctic, such as permafrost thaw, may impact the supply of reactive trace metals in the region.

Summary: The global overturning ocean circulation is crucial for global climate and can be traced using neodymium (Nd) isotopes. However, the value of Nd isotopes as a circulation tracer has been questioned due to various processes that can modify seawater Nd isotope ratios. This study investigates the integrity of Nd isotopes as an ocean circulation tracer in the Southwest Atlantic and confirms their potential for reconstructing past ocean circulation changes.

Summary: The bromine isotope compositions of magmatic and hydrothermal minerals from the Ilimaussaq intrusion in South Greenland were determined to constrain the origins of the melt and hydrothermal fluids. The data suggests that there is a negative Br isotope fractionation during the crystallization of sodalite and tugtupite, leading to varying delta Br-81 values in different stages of mineral formation. This indicates a complex evolution of the hydrothermal system involving different sources of fluids.

Summary: This study investigates the hydrogeological regime and structural evolution of the Cretaceous subduction zone in Hokkaido, Japan, by analyzing the timing and migration pathways of fluids emitted at ancient methane seeps. Results show that two fluid discharge events occurred during the accretionary stages, originating from the forearc basin rather than the underplating materials. The seeping fluids experienced interactions with the mafic rocks of the lower Sorachi ophiolite and siliciclastic sediments of the Yezo Group.

Summary: The study found that the circulation structure in the far South Atlantic underwent changes throughout the last glacial cycle, contradicting the common conception of the upper circulation cell in the Atlantic being shoaled at the Last Glacial Maximum. Despite little change in mid-depth ocean structure, greater stratification between mid-depth and abyssal sites developed, which may have contributed to glacial carbon storage in the deep ocean.

Summary: A novel method for synthesizing 1,4-dicarbonyl compounds is described, involving the generation of zinc enolates from alpha,alpha-dibromoketones through a diethylzinc-mediated halogen-metal exchange, followed by their reaction with alpha-bromocarbonyl compounds. This cross-coupling reaction enables the selective formation of zinc enolates from alpha,alpha-dibromoketones in the presence of alpha-bromocarbonyl compounds, leading to the synthesis of 1,4-dicarbonyl compounds. Chiral 1,4-dicarbonyl compounds can be obtained through enantioselective bromination of aldehydes and subsequent cross-coupling reaction with chiral alpha-bromoaldehydes and alpha,alpha-dibromoacetophenones.

Summary: Subjecting a physical system to extreme conditions is a common method to gain a better understanding of its organization and structure. The investigation of isotopes with different neutron-to-proton ratios than stable nuclei is an important test for nuclear-structure theories. This study reports the first observation of the decay of O-28 and 27O isotopes and compares their decay energies with theoretical models. The results have implications for the understanding of nuclear structure.

Summary: This study investigates nucleon removal reactions and validates the models used to calculate the removal reaction cross sections. Three different nucleon removal reactions were performed and the partial cross sections to individual final states were determined by detecting the residual nuclei in coincidence with gamma rays. Comparison between measured and calculated cross sections reveals that the theoretical description of the removal process is in better agreement with the data when removing weakly bound nucleons.
