Summary: The study reveals that anthropogenic lead is widespread and dominant in the western Arctic Ocean, with significant contributions from historic aerosol lead deposited from Europe and Russia during the 20th century. The remobilization of this lead, especially in water layers with higher concentrations, highlights the impact of human activities and environmental changes on the Arctic. Detecting 20th century Eurasian lead in deep water also provides insights into ventilation ages and helps constrain sources of contaminants in Arctic seawater.

Summary: Using nifH gene sequencing, this study revealed variations in composition, community structure, and assembly mechanism among diazotrophic communities in the high Arctic fjords. Differences in water mass types and vertical segregation of diazotrophs were found to be influenced by salinity and dissolved oxygen content. The formation of diazotrophic communities was primarily dominated by stochastic processes, affecting nitrogen fixation in the Arctic fjord.

Summary: This study investigates the deposition concentration, multiple origins, and release form of iron in glaciers and snowpack of the northeast Tibetan Plateau. The results show a heterogeneous geographic distribution of iron content, with aeolian dust and anthropogenic aerosols likely being the important sources. The release flux of dissolved iron reaches its peak in July, with meltwater showing higher concentrations than glacier snowpack. The Tibetan Plateau glacier is an important potential reservoir of dissolved iron and may have a significant impact on downstream ecosystems through iron biogeochemical cycle.

Summary: Glacier melt water is an important freshwater source for many regions, but little attention has been given to its contribution to subarctic watershed-scale geochemistry and runoff. This study conducted a six-year geochemical hydrograph separation study of melt season daily streamflow in a glacierized watershed in Interior Alaska. The results showed that glacier discharge is the largest seasonal contributor to total warm season lowland streamflow, with large daily variability. The study also highlighted the importance of considering the variability of source contribution in glacierized watersheds when studying hydrologic function.

Summary: The generation, transport, storage, and drainage of meltwater in Greenland Ice Sheet are crucial for the subglacial system. This study focuses on the repeat filling and drainage events of subglacial lakes in Greenland. The findings show that a collapse basin in northeast Greenland experienced continuous filling by surface meltwater, leading to a significant surface elevation change. Factors such as the volume of water stored in the lake and bedrock relief play a role in regulating the episodic filling and drainage of the lake. Additionally, a substantial portion of surface meltwater does not reach the bed, hinting at potential processes like refreezing and firn aquifer storage.

Summary: This study proposes using authigenic carbonate δ18O from glacial lakes as a quantitative proxy to estimate glacier meltwater variations. It reveals significant fluctuations in glacier meltwater in the Western Kunlun Mountain region over different time periods and suggests that about 20% of regional glaciers melted from the Early to Late Holocene, likely influenced by summer temperatures and melting potential accumulation. The study also warns of severe threats to Tibetan Plateau glaciers due to current rates of global warming.

Summary: This study investigates the concentration and behavior of dissolved iron (dFe) in the East China Sea (ECS) and reveals its close relationship with nutrient cycling and the development of sub-surface chlorophyll maximum. The study also finds that mass transport over the ECS shelf is dominated by input from the Taiwan Strait Warm Water, atmospheric deposition, and exchange with the open boundary current offshore. Additionally, the export of dFe from the ECS nourishes other marginal seas and the Kuroshio further downstream, highlighting the critical role of marginal seas in bridging terrestrial and oceanic Fe biogeochemistry.

Summary: Deposition of aerosols to the surface ocean is an important factor affecting primary production in the surface ocean. This study collected data on aerosol Pb-210, Po-210, and Be-7 fluxes during a research cruise in the Pacific Ocean. The results showed that Pb-210 fluxes were low near the Alaskan margin, increased at around 43 degrees N, and then decreased. The study also found good agreement between Pb-210 fluxes and long-term land-based fluxes, as well as data from another research cruise in the East Pacific Ocean.

Summary: Low-salinity meltwater from Arctic sea ice and snow cover forms under-ice meltwater layers that can create false ice bottoms. A study conducted as part of the MOSAiC project revealed that the areal coverage of false bottoms in a specific area was 21%. The presence of false bottoms reduced bottom ice melt by up to 8%, primarily due to a decrease in ocean heat flux. The thickness of under-ice meltwater layers varied depending on ice age and thickness. The study also highlighted the role of thick ice and ridge keels in confining the accumulation of meltwater. While a thermodynamic model could explain false bottom growth, it couldn't accurately predict observed bottom melt rates.

Summary: The East African rift system is formed above mantle upwellings and the formation of rifts is related to lithospheric thinning and magmatic activity. The amount of splitting varies spatially and the fast axes are predominantly parallel to the orientation of the rifts. Thick lithospheric modules have less splitting and different orientations, which may indicate mantle plume flow. Splitting rotates and increases in strength as it enters the rift zones, suggesting that the anisotropy is mainly present at shallow depths.

This study compares the Fe-XANES oxybarometry method with the V-in-olivine method for evaluating fO(2) in MORB lavas. The results show that the V-in-olivine method is not applicable to samples with low MgO content, and that the majority of Archean komatiite sources have lower fO(2) than modern MORB.

Summary: The volatile components CO2 and H2O play a major role in mantle melting and heterogeneity. In this study, Ca isotopes were used to trace the lithological heterogeneity in alkaline magmatic rocks. The results revealed the presence of K-richterite and carbonate components as the source of alkaline magmas with low delta 44/40Ca values. These findings highlight the importance of Ca isotopes as a robust tracer of lithological variation caused by volatiles in the Earth's upper mantle.

Summary: Although the current approach to estimate catchment-wide denudation rates using only 10Be concentrations has made significant progress in geomorphology, this study argues for the inclusion of 26Al measurements and testing of steady-state assumptions in slow eroding, formerly glaciated landscapes. The study conducted measurements of both 10Be and 26Al in stream sediments from the Vosges Massif in France and found that elevation, slope, channel steepness, and precipitation were the primary factors controlling denudation rates. The study also revealed a significant relationship between the extent of past glaciation and the cosmogenic (un-)steadiness in the stream sediments.

Summary: Numerical models of Earth's mantle dynamics can predict the vigour and mixing of mantle flow, and the average slab sinking rates are an unexplored parameter that can provide intrinsic information on these characteristics. Through numerical experiments, it has been found that slab sinking rates are strongly correlated with mantle convection and mixing, and may explain geochemical observations from hotspot volcanoes.
