Summary: This study constrained the relative contributions of major dust source regions to the global dust cycle, finding that North African and Asian regions are the main contributors, and dust loading peaks in local spring and summer. The data obtained in this paper can be used to improve constraints on dust impacts on clouds, climate, biogeochemical cycles, and other parts of the Earth system.

Summary: This paper proposes a new method of enriching urease-producing microbial communities in seawater in a non-sterile environment to solve the dust problem caused by sandstorms. The dust suppression performance of the enriched microorganisms under different pH conditions was explored. The results showed that the alkaline environment promoted the transformation of CaCO3 to more stable calcite, and the mineralization rate reached its maximum value at pH = 10 on the 7th day.

Summary: The shallow earthquakes that struck the Black Rock Desert volcanic field in Utah in September 2018 and April 2019 were unique in their seismic signals, surface deformations, and aftershock sequences, ruling out an isotropic source. The enhanced earthquake catalog constructed using advanced techniques revealed a short-lived aftershock sequence, leading to the hypothesis that the shallow earthquakes are related to the volcanic field.

Summary: The study in the desert steppe of Inner Mongolia, China, found that finer soil particles generally had higher SOC contents, leading to a proposed method to calculate SOC content in aeolian sediment. The calculated results were highly consistent with the measured results, providing a more precise estimation of SOC loss induced by wind erosion. Simulated results showed SOC loss induced by dust emissions ranging from 0 to 39 g/m(2)/y during the period of 2001 to 2017, which could be valuable for carbon budget estimation in the desert steppe.

Summary: Planetary boundary layer height (PBLH) is a crucial factor for dust storms and dust devils in desert regions. Existing parameterization schemes have limitations in reflecting the diurnal cycles of PBLH in these areas, which affects global dust-aerosol emission evaluation. A new theoretical model based on the heating effect of dust aerosols and the vertical profile of virtual potential temperature is developed, and successfully parameterized using observations in northern China. The new scheme shows better agreement with observations compared to existing schemes, and provides improved evaluation of dust-devil emissions.

Summary: In the first two decades of the 21st century, the population of American black bear (Ursus americanus) has rebounded and expanded its range into previously extinct areas. Habitat quality and availability are crucial factors limiting the range expansion, especially in western Nevada, USA. Through various data collection methods, including cameras, hair sampling, genotyping, and GPS tracking, we found that black bears preferred the Sierra Nevada with conifer land cover over the Great Basin Desert. The population density of black bears in the Sierra Nevada was over 4 times higher than in desert mountain ranges, indicating limited range expansion into the western Great Basin due to habitat quality and availability.

Summary: This study establishes baselines for the dietary practices of past populations in the Eastern Baltic region using multi-isotopic analysis. The results show clear differences in carbon and sulfur isotopic values between marine and terrestrial species, while freshwater fish display overlaps with both ranges. Herbivores show variation in isotopic values based on region. This study provides valuable temporal and geographical references for studying local ecologies and interpreting human data.

Summary: After conducting comprehensive research on stratigraphy, sedimentology, and geomorphology, it was found that the Sunite Deflation Basin is a giant shell-like deflation basin located between the Otindag Sandy Land and the Tunggur Platform. With an area of over 8000 km2 and a volume of -393 km3, it is the second largest deflation basin in the world and the largest in Asia. Preliminary estimates suggest that it releases about 216 km3 of dust, which can be deposited up to -5.8 meters thick in the downwind loess area near Chifeng in Northeast China.

Summary: The dispersion and interaction of trace elements (TEs) in abandoned mine materials pose a significant problem for terrestrial and aquatic environments. This study focuses on the particle size distribution and TE associations with mine tailings and locally derived sediments transported by water in an arid region. The results reveal variations in the distribution of different TEs on particles, influenced by the type of ore and particle size. The study highlights the enrichment of certain TEs in downstream areas due to the transportation of contaminated sediments in arid regions.

Summary: This study analyzed deep-sea sediments from the Black Sea, determining isotopic values and elemental concentrations in the samples. Results showed different ranges for organic and inorganic components, as well as variation in isotopic values in extracted water. These preliminary findings will contribute to a new paleoclimatic reconstruction using stable isotopes in the deep-sea sediments from the Black Sea.

Summary: The Atacama region in Northern Chile is known for its extremely dry desert and significant lithium reserves. This study suggests that ignimbrites, a type of volcanic rock, may be the main source of lithium in the region due to their high lithium concentrations. The study also highlights the importance of volcanic eruptions and subsequent water-rock interactions in determining the distribution and isotopic composition of lithium.

Summary: The forensic analysis of stable isotopes is used to geo-source natural or semisynthetic drugs like cocaine and heroin. A novel methodology to isolate morphine from opium for isotopic analysis is described in this study. The data shows that nitrogen ratios differentiate samples from different regions, while carbon ratios can distinguish samples from Southwest Asia.

Summary: The study shows that BC in the relatively pristine environment of East coast of Malaysia has a higher degree of aromatic condensation and lighter isotopic composition, while the developed environments of West and South coast have higher anthropogenic impacts. The isotopically light composition of BC in Malaysia is possibly influenced by biomass burning with C-3 plants and the use of natural gas in energy mix.

Summary: Arsenic release related to gold mining activity can alter surface water and sediment chemistry, with the toxicity of arsenic controlled by various geochemical conditions. Continued lime treatment is crucial to reduce arsenic mobility in mine wastes following mine closure, particularly for sites where wastes are released directly into watersheds without containment infrastructure.

Summary: This study presents the isotopic compositions of Mg, Ca, and Sr in pore fluids, bulk carbonates, planktonic foraminiferal tests, and bulk clays from multiple drilling sites. The objective is to understand the major processes controlling marine pore fluid composition and their effects on diagenetic alteration in carbonate sediments. The results suggest that calcite recrystallization and clay authigenesis play significant roles in the isotopic variations observed.

Summary: Sedimentary pyrite is an important geological archive, but it can be altered by diagenetic and hydrothermal processes. This study successfully trained machine learning algorithms to distinguish pyrite origins using trace element data. The approach was validated and applied to identify the origins of pyrite in two sedimentary successions in South China.
