Summary: This study examines the evolution of Holocene aeolian activity in the Gonghe Basin in the northeastern Qinghai-Tibet Plateau. The results show that strong aeolian activities occurred during the Early Holocene (around 13-9 ka), indicating a dry climate. Soil development reached its peak and aeolian activity was lowest around 7-5 ka. Increased sand content in the Late Holocene suggests enhanced human activities in the region.

Summary: Scientific knowledge advances through discussions that involve hypotheses, methods, and results, where contradictions play a positive role by developing new theoretical- methodological approaches. In order to promote scientific progress, agreements and disagreements should be confined to the scientific domain and be based on ethics to avoid conflicts of interest. In response to a submission entitled "Comments on Souza et al. (2022) Recent geomorphological changes in the Paraiba do Sul delta, South America East Coast" to the journal Progress in Physical Geography: Earth and Environment, this article clarifies doubts related to the original paper. The comments focused on da Rocha et al. (2019), a locally published article that failed to fully address the complexity of processes and geomorphological dynamics regarding delta evolution, as well as the parameters used in the geochronological analyses according to international literature. Finally, the discussions in the original article contribute to advancing knowledge about the responses of the Paraíba do Sul delta to the Little Ice Age.

Summary: The study examined the coastal barriers of Sa limeiro Cape in Rio de Janeiro, Brazil, using geomorphological mapping, topographic surveys, ground-penetrating radar profiles, and optically stimulated luminescence (OSL) dating. The research aimed to reconstruct the spatial and temporal evolution of the coastal barriers and understand their role as potential archives for long-term environmental dynamics. It found that sedimentary capes can serve as geoarchives for the reconstruction of coastal processes over Holocene timescales.

Summary: The development of functional portable OSL readers allows practitioners to rapidly acquire luminescence signals from geological materials, providing expedient chronostratigraphic insight for late Quaternary complex depositional systems. These portable readers can be used to elucidate sedimentary variations, interpret sediment processes, and approximate numerical burial ages, offering potential future directions for research in the field.

Summary: Low fluvial terraces in Brazil exhibit azonal spatialization and their genesis is related to river dynamics and Holocene climate events. This study used Optically Stimulated Luminescence (OSL) to obtain absolute dating information for 114 samples from 30 rivers in Brazil, aiming to identify relationships between variables and the relationship between low river terraces and human occupation.

Summary: This study examines the paleoglacial history and paleoclimatic conditions during the Last Glacial Maximum (LGM) and Lateglacial (LG) in the Songlong and Zhuxi valleys in southeastern Tibet. Two sets of moraines were dated using Be-10 exposure and OSL dating, indicating two glaciations occurred around 20-21 ka and 14-16 ka, corresponding to LGM and LG. Temperature drops during LGM-LG were calculated to be 6.3-7.8 degrees C with precipitation at 40-60% of present-day value, consistent with other climatic records from the Tibetan Plateau. Glacial advances in monsoon-dominated southeastern Tibet were likely driven by low temperatures rather than high precipitation during LGM-LG.

Summary: Aeolian sediments serve as important geological archives for paleoclimate changes. This study investigates two aeolian sand dune sections in the Hunshandake Sandy Land, northeast China, to explore regional paleoclimatic changes during the Holocene. The results reveal arid climate conditions during the early Holocene, stable dunes with vegetation under a warm and humid climate during the mid-Holocene, and a return to arid and semi-arid conditions in the late Holocene.

Summary: The morphodynamic approach to coastal evolution is crucial for coastal management. In this study, the Holocene evolution of the Bega River estuary and Tathra Beach coastal barrier was examined. The findings revealed the infilling of the estuary and the deposition of the coastal barrier, highlighting the importance of understanding these processes for management decisions.

Summary: The study examines the significant role of alluvium coastal physiography in influencing coastal morphodynamics, using dating records and data analysis to reveal the geological and geomorphological evolution of the Subarnarekha chenier delta. It suggests that the development of the chenier plain is a result of various factors, with the coastal topographic diversity influenced by historical river channels and present-day coastal processes.

Summary: This study aims to determine the conditions and explain the local and different histories of barrier coast evolution in the Holocene. A 35 km long coastal zone in the eastern Pomeranian Bay was explored using various methods. Different deposits, including barrier subsoil deposits, barrier deposits, and river delta deposits, were identified. The study found that the coastline migrated southwards due to climate warming and rapid sea level rise. Three different histories of barrier coast development were observed, influenced by lithology, relief, and sand availability.

Summary: Researchers conducted experiments to investigate the impact of experimental artifacts on the scatter in OSL profiles measured from rock surfaces. Results indicate that sample temperature, both during preheating and stimulation, may have a significant influence on the obtained OSL profiles. To reduce this effect, it is suggested in future studies to place samples in metal cups, decrease the heating rate, and increase preheating and holding times prior to optical stimulation.

Summary: Stable organic carbon and nitrogen isotopes were used to reconstruct the past environment in the southern Carpathian Basin, highlighting the importance of decalcification methods for accurate carbon isotope analysis in loess-palaeosol sequences. The study found that the choice of decalcification method affects the results significantly, with the fumigation method showing incomplete removal of carbonates. Results also indicated that samples with TOC content <0.2% have a higher risk of misinterpretation of their carbon isotope ratios.

Summary: This study re-investigated two LPS profiles in Germany, establishing new quartz OSL and polymineral IRSL chronologies and applying Bayesian age-depth modeling to resolve original age inversions. The reinterpretation of grain-size data through end member modeling analyses provided insights into geomorphic processes and timing. The findings highlight variations in sedimentation rates over time and link certain grain size characteristics to the extent of the ice sheet and changes in wind patterns.

Summary: This study presents a comprehensive inventory of future glacial lakes in High Mountain Asia by analyzing the subglacial bedrock of approximately 100,000 glaciers. It identifies numerous overdeepenings that could potentially lead to glacial lake outburst floods (GLOFs), with a shift in lake area, volume, and hazard towards the Karakoram region from the southwestern Himalayan region. The findings provide valuable insights for anticipating emerging threats and potentials related to glacial lakes in the region.

Summary: This study investigates the late Quaternary development of the sedimentary system of Orog Nuur Basin in southern Mongolia, revealing the palaeoenvironmental changes and multiple lake level variations. Through paleoshoreline mapping and dating, researchers identified the lake level history and found the expansions during late MIS 5 and MIS 3 were of similar magnitude. The study highlights the valuable landscape and palaeoenvironmental reconstructions offered by the Orog Nuur Basin archives for supraregional comparisons.

Summary: This article introduces a pre-processing step in remote-sensing data processing that focuses on improving the accuracy of existing algorithms in polar and high mountain regions. The proposed self-training approach, which uses a larger network architecture at each stage and generates new training labels, effectively corrects noisy labels. Experimental results show that this approach outperforms existing algorithms in terms of overall accuracy.
