Summary: Ripples, TARs, dark-toned sand sheets, and dunes are common aeolian bedforms on the Martian surface, providing insights into present-day Martian sediments and regional aeolian processes. This study investigates these features in an unnamed crater in Terra Sabaea, Mars, revealing differences in composition and origins, suggesting potential local and external sources for the sediments. The findings highlight the complex dynamics of aeolian processes on Mars and the potential recycling of sediments from various sources.

Summary: Chronostratigraphic records in the drylands of north China provide important archives to reveal the dynamic connections between climate changes and aeolian system behavior. This study investigates aeolian sediment accumulation around the Tengger Desert during the late Quaternary, showing control by multiple factors such as wind, aridity, sediment availability, and preservation capacity. The importance of sampling at multiple sites and the synchronous accumulation of aeolian sand and sandy loess at certain periods are emphasized.

Summary: In the Makgadikgadi Basin, a new formative mechanism for crescentic sand mounds has been proposed based on numerical modeling and optically stimulated luminescence (OSL) dating. The uneven moisture distribution on the pan surface can lead to the development and stabilization of these dunes, growing upwind from the point of initial deposition. These findings suggest that the formative mechanism of these mounds may be dependent on the interaction between differential drying of the pan surface and the competence of the aeolian sediment transport system across the pan floor.

Summary: This article summarizes the process of sand drift erosion in the Gobi desert and finds that the erosion amount of saltating particles is closely related to friction velocity and gravel coverage. The peak value of saltation erosion rate increases with friction velocity and follows a power-law relationship. It is also found that the damage height caused by saltation erosion is primarily concentrated in the range of 0.03 to 0.15 meters and increases linearly with friction velocity.

Summary: Large saline lakes, including Lake Urmia, are drying up rapidly and experiencing the emergence of sand dunes. This study analyzes the mineralogy and sedimentology of the exposed lakebeds to understand the morphology, evolution, and migration rate of the dunes. High migration rates are observed, influenced by factors such as wind potential, precipitation decline, and atmospheric circulations. The findings have implications for the management and policies of drying saline lakes worldwide.

Summary: This study reviews and discusses multiple hypotheses regarding the initiation of transgressive aeolian sand sheets and dunefields. Direct evidence supporting these hypotheses is largely lacking. However, research in South Australia provides unequivocal evidence that large-scale shoreline and dunefield erosion does lead to the development of a new transgressive aeolian sand sheet. The initiation process occurs at an incredibly rapid rate and may have implications for future sea level rise and climate change.

Summary: This study uses geochronological research and optically stimulated luminescence dating to determine the depositional ages of aeolian sands and loess in the northern Upper Rhine Graben. The results show that aeolian sand deposition occurred from 17 to 10 thousand years ago, confirming a deposition during the end of the Wurm glaciation, while loess deposition took place from 42 to 17 thousand years ago. Furthermore, the study also suggests a younger period of anthropogenic induced redisposition of aeolian sands around 4 thousand years ago.

Summary: This article investigates how to design economical and effective sand fences to protect solar energy parks in desert areas from the encroachment of moving sand and burial by migrating dunes. The study provides design suggestions for sand fences based on a combination of theoretical calculations and field measurements, and serves as a reference for designing sand fences in sandy areas.

Summary: The study in the Khartouran Erg of NE Iran showed that sand drift potential is low in the region, with winds mainly coming from the east and northeast directions. Winter had the highest wind speeds while summer had the lowest, with an annual average wind speed of 3.3 m/s. Climate changes were found to influence the intensity of sand dune mobility.

Summary: The Selima Sand Sheet is a vast low-relief area located in the hyperarid region of the Eastern Sahara. It is composed of laminated aeolian sands, with active chevron bedforms visible on satellite images. The sand sheet covers Quaternary paleosols that reflect varying degrees of soil development over time. The timing of aeolian sedimentation provides insights into paleoenvironmental changes and pedogenesis in this region.

Summary: The study found that on the leeward side of barchan dunes, recovering flow triggers wind erosion through unsaturated flux, affecting the length of the erosion zone. Sand supply and wind erosion rate collectively determine the spatial distribution patterns of barchan dunes and their morphological changes.

Summary: EICP combined with PVA improves the solidification of aeolian sand and enhances its durability. In practical applications, 3% PVA concentration is sufficient for sand treatment. SEM images and mercury intrusion capillary pressure tests indicate that PVA films enhance the bonding between soil particles, fill large pores in the soil, and improve the performance of the EICP+PVA-solidified sand.

Summary: This study focuses on the morphodynamic changes of an artificial dune on a sandy beach in Italy, using UAV and elevation data products. By comparing DEMs and GPS data, and applying uniform thresholds for change detection, the study highlights the significance of volume change estimations and discusses uncertainties related to morphological variations.

Summary: The Old Red Sand, a late Quaternary deposit in coastal South China, is not a single sand body but a mixture of near-source coarse beach sand and exotic fine dust. The fine fraction, which includes silt and clay, plays a key role in the cementation and redness of the sand body. The deposition characteristics, sedimentary environment, and provenance of the fine fraction are significantly different from those of the coarse fraction.

Summary: Grain size analysis is a powerful method for determining depositional environment. The study conducted grain size analysis on samples from the Kordofan Region in Central Sudan and found that the predominantly Holocene sand sequences were deposited in an aeolian environment, with sediments transported from the north to the south. The results also indicated that the sand sequences were influenced by both distal, fine-grained Saharan material and proximal, coarser-grained sand from Late Pleistocene aeolian dunes.

Summary: In this study, the decadal progress of eolian erosion in the southern Gobi Desert was analyzed using satellite data and climatic variables. The results showed that land degradation and sand and dust generation in the desert are significantly controlled by precipitation distribution and trends, with climatic conditions shifting towards an unfavorable direction. Anthropogenic activities have also contributed to the expansion of the transition zone between the desert and vegetated terrain.
