Summary: This study presents high-resolution paleoenvironmental and archaeological data from Neumark-Nord in Germany, revealing the impact of Pleistocene hunter-gatherers on their ecosystems. The ecological footprint of hominin activities, including fire use, shaped vegetation structure and succession in the lake landscape, suggesting human involvement in vegetation transformation. Neumark-Nord, with an age of around 125,000 years, provides an early example of the role of hominins in influencing vegetation dynamics.

Summary: This paper investigates in detail a layer of red sediments deposited along the northwestern Atlantic Ocean 125,000 years ago. It finds that this deposit was a glacial outburst event similar to the one that occurred 8,200 years ago. The freshwater discharge associated with this event may explain several global abrupt changes, including a reduction in North Atlantic Deep Water and the resurgence of Antarctic Bottom Water. The study suggests that the mechanism behind this event is a significant part of the deglacial sequence.

Summary: Using Antarctic ice records, we estimated the tropospheric ozone burden during the last interglacial period and found a reduction compared to the late pre-industrial Holocene. This is consistent with the hypothesis of reduced biomass burning caused by the extinction of megafauna.

Summary: Climatic oscillations during the Pleistocene, particularly the Last Interglacial period, led to significant changes in global sea level and the spatial distribution of marine and terrestrial ecosystems. The study provides evidence of an extant, inland mangrove ecosystem as a relict of the Last Interglacial period, demonstrating the long-lasting impact of sea level changes on tropical landscapes and species ranges.

Summary: Like many coastlines around the world, the Korean Peninsula experienced higher sea levels during the last interglacial. However, the geological record of this highstand differs between the eastern and western coasts. The tectonically active east coast has uplifted marine terraces, while the stable west coast has tidal flats and rias. This study reviewed existing data on sea levels during the last interglacial on both coasts of the Korean Peninsula and found that vertical movement has affected the elevations on the east coast, while the west coast has likely remained relatively stable.

Summary: This study presents a Pulleniatina obliquiloculata Mg/Ca-derived thermocline water temperature record covering the past 270,000 years in the south of the Lombok Strait, revealing changes in thermocline water temperature reflecting the balance between wind-driven Java upwelling and the Indonesian Throughflow (ITF) thermocline transport. The relative strength of ITF through time can be deciphered by the evolution of the TWT gradient between the upwelling site and the Lombok site, indicating a significant precession-related component influencing the ITF intensity at the Lombok site.

Summary: Using microfossil records from the central Arctic Ocean, it has been shown that during the Last Interglacial, sea-ice extent was substantially reduced and summers were likely ice-free. These findings indicate that the current state of the central Arctic Ocean is not typical and suggest the possibility of a seasonally ice-free Arctic Ocean in the near future.

Summary: Dryland is vital to a third of the world's population, and studying its climate during the Last Interglacial period (LIG) can provide insights into its behavior under warmer conditions. Research findings suggest that LIG drylands were 37% wetter and experienced changes in spatial distribution. Precipitation alterations, mainly driven by the redistribution of insolation and heat, contributed to more than 72% of the changes in dryland aridity. However, these changes in the LIG do not fully resemble future warming scenarios, indicating that it may not be an accurate analogue for the future dryland climate.

Summary: The study shows that vegetation changes during the Last Interglacial period in the Arctic had a positive feedback on climate warming, but the lack of high-latitude records limits the complete understanding of vegetation distribution during that time.

Summary: The study reveals that summer warming is driving a greening trend in the Arctic, potentially amplifying climate change. Past episodes of Arctic warming, such as the Last Interglacial, can help understand vegetation response to temperature change. Ancient DNA records from lake sediment provide insights into vegetation distribution during the Last Interglacial and highlight the importance of combining traditional and molecular approaches for paleoenvironmental studies to better anticipate a warmer future.

Summary: This study aims to derive calcite dissolution rates in a reservoir sandstone by combining mineral surface experiments with scanning interferometry and core plug experiments. The 3D geometry of calcite cement phase inside rock cores was characterized using X-ray micro-computed tomography and was used to upscale the rates from mineral surface to core scale. The results show that the upscaled total dissolution rates were reasonably accurate, indicating the potential suitability of this method for upscaling the mineral surface rates to the core scale.

Summary: This study investigates caves in the southern part of Kazakhstan, Central Asia, through field survey and micromorphological analysis. The preservation of cave deposits is influenced by the redistribution of sediments within the caves and the erosional processes shaping the semiarid landscapes. This research fills a gap in the geological archaeology of Central Asia and demonstrates the analytical potential of micromorphology even within the limitations of rigorous survey projects.

Summary: This study presents the results of extensive field surveys conducted in the Inner Asian Mountain Corridor of Kazakhstan, aiming to locate prehistoric raw material sources. The study also provides a detailed petrographic description of lithologies exploited during the Palaeolithic of Kazakhstan. The findings suggest that the direct procurement strategy was the most common at the stratified sites, but evidence of both direct and embedded procurement was found in a specific site.

Summary: The eastern Kendeng Hills in Java, Indonesia, provide a stratigraphic record that represents the emergence of eastern Java from the sea. Recent studies have shown that the process of emergence was complex, influenced by various factors, resulting in a varied depositional record. Through a re-interpretation of the stratigraphic record, the researchers identified it as a previously unrecognized embayment fill, changing our understanding of the timing of hominin migration to Java.

Summary: The digital rock physics (DRP) workflow can be used to obtain pore-scale properties by creating a reliable digital twin of porous media. This requires reliable imaging and computing power. Determining the appropriate image resolution is challenging due to the trade-off between resolution and the representative elementary volume (REV). This study aims to estimate hydraulic pore-scale properties using the Minkowski morphological functionals and determine the effect of image resolution and artificial rebinning on the REV values.

Summary: Excessive water production in mature reservoirs is a major problem that reduces hydrocarbon production and economic reservoir lifetime, as well as poses environmental issues. The injection of pH-sensitive microgel has emerged as a promising method for water shut-off and deep conformance control, offering advantages such as deeper penetration, lower operational costs, and reversibility of the swelling process. However, the acid pre-flushing step required for this treatment approach increases operational costs. This review explores recent progress and challenges in acid pre-flushing and pH-sensitive microgel treatment, including synthesis, characteristics, mechanisms, and modeling approaches.

Summary: The investigation of a hillslope debris flow in Biersdorf, Germany using a comprehensive geomorphological-geophysical approach revealed that the geomorphological and geotectonic position played a crucial role in triggering the flow. Combining field studies and modeling techniques, the researchers were able to better understand the triggering mechanisms and process dynamics of such events. The study provides valuable insights for risk assessment and hazard prevention of hillslope debris flows in mountain regions.
