Glaciers including ice sheets, ice caps, and mountain glaciers cover more than 10 % of the Earth's land area. Borehole drilling in glaciers serves a wide range of scientific purposes, such as the evolution of the Earth's climate and environment, formation and movement of snow and ice, impact of glacial phenomena on landscapes, subglacial environment, and so on. Geophysical logging is a crucial component of most ice-drilling projects, providing valuable in-situ data on the physical and structural properties of the natural snow and ice surrounding the borehole. These properties include temperature, density, creep parameters, optical characteristics, visual stratigraphy, and subglacial electrical resistivity. However, conventional geophysical logging techniques are often not suitable for ice due to its distinct physical properties. Over the past six decades, specialized downhole tools—such as light-emitting loggers and optical televiewers—have been developed to image borehole walls and resolve stratigraphy at resolutions comparable to those of ice core analysis. These advanced methods bridge ice-core data with regional glaciological parameters, such as ice flow dynamics and geothermal heat flux. This paper provides an overview of current and emerging borehole logging techniques and their applications in glacier research, while a subsequent paper discusses long-term in-situ borehole observatories.

Rapidly expanding glacial lakes are transforming cryospheric, hydrologic, ecologic, and societal dynamics worldwide. They affect water resources, hydropower, sediment transport, and carbon cycles while also being influenced by the increased instability and interactions with their surroundings due to global warming. Here, we present a state-of-the-art synthesis on glacial lakes, focusing on their ecohydrological and geomorphological importance. First, warming-driven deglaciation is inducing extensive glacial lake expansion, enhancing freshwater storage capacity and hydropower potential. Sediment-rich meltwater promotes underwater weathering, positioning glacial lakes as important yet underrecognized carbon sinks, with a preliminary global carbon consumption flux estimated at over 0.26 Tg C-CO2 yr−1. Second, glacial lakes profoundly reshape high mountain landscapes by acting as sediment sinks, drivers of catastrophic sediment transport events, and modulators of cascading hazards. They trap sediment fluxes from glacier-fed systems, creating long-term geological archives and influencing downstream geomorphology. Extreme lake outbursts can mobilize vast quantities of sediment, dramatically altering river networks, floodplains, and valley morphology. Moreover, interactions between expanding proglacial lakes, retreating and calving glaciers, and unstable ice-rich moraine dams heighten geomorphic instability under ongoing warming, increasing the susceptibility of lake outbursts. Overall, glacial lakes can significantly affect geomorphic evolution, biogeochemical cycles, and socioeconomic activities in the surrounding areas up to tens of kilometers downstream. Future research requires systematic field planning and monitoring to reveal these critical interactions and improve local risk management.
迅速扩大的冰川湖泊正在改变世界范围内的冰冻圈、水文、生态和社会动态。它们影响着水资源、水电、泥沙运输和碳循环,同时也受到全球变暖导致的不稳定性增加和与周围环境相互作用的影响。在这里,我们提出了一个最先进的冰川湖综合,重点是他们的生态水文和地貌学的重要性。首先,全球变暖导致的冰川消融导致冰湖大面积扩张,增强了淡水储存量和水电潜力。富含沉积物的融水促进了水下风化,将冰川湖定位为重要的但尚未得到充分认识的碳汇,初步估计全球碳消耗通量超过0.26 Tg C-CO2 yr - 1。其次,冰川湖作为沉积物汇、灾难性沉积物运输事件的驱动因素和级联灾害的调节器,深刻地重塑了高山景观。它们捕获了冰川补给系统的沉积物通量,形成了长期的地质档案,并影响了下游的地貌。极端的湖泊爆发可以调动大量的沉积物,极大地改变河网、洪泛平原和山谷的形态。此外,扩大的前冰期湖泊、退缩和崩解的冰川以及不稳定的富冰碛垄之间的相互作用加剧了持续变暖下地貌的不稳定性,增加了湖泊溃决的易感性。总体而言,冰湖可以显著影响下游数十公里范围内周边地区的地貌演化、生物地球化学循环和社会经济活动。未来的研究需要系统的实地规划和监测,以揭示这些关键的相互作用并改善当地的风险管理。

In the Western Alpine Foreland Basin (WAFB), Late Eocene and Miocene periods were characterized by longitudinal sediment routing systems: The first one was situated within the turbidite basin during the underfilled phase and exhibited a northward orientation toward the Swiss Basin, whereas the second was located in the Rhône Valley during the overfilled phase and was directed southward toward the Mediterranean Sea. The transition between these two periods occurred during the Oligocene, which corresponds to both the underfilled/overfilled transition and the early overfilled period. In this study, we provide new fieldwork observations, seismic and well data interpretations, biostratigraphic analyses and a literature synthesis to reconstruct the palaeogeographic and source-to-sink evolution of the WAFB from Priabonian to Aquitanian. The aim is to discuss this reorganisation of sediment routing in relation to the evolution of the Alpine orogenic wedge, as well as the structural inheritance and the suite of geodynamic events that affected southeastern France during the mid-Cenozoic. We divided the WAFB sedimentary formations into four depositional sequences (S1 to S4). During the deposition of the first two sequences (Priabonian to early late Rupelian; ∼37.4–28.8 Ma), the WAFB routing system was influenced by the end of the Pyrenean-Provençal orogeny, the European Cenozoic Rifting System (controlling the Rhône Valley s.l.) and the Alpine orogenic wedge (controlling the Alpine foredeep). The very first connection between the Alpine domain and the Rhône Valley is established at ∼30 Ma, during the late Rupelian (S2 highstand), controlled by E-W inherited Pyrenean-Provençal structures implying a ‘broken foreland’. In the meanwhile, from the Dévoluy Basin and northward, the orogenic wedge controlled a classical, although thin, foreland basin characterized by a northward sediment routing connected to the Northern Alpine Foreland Basin. Most of the S3 sequence (Latest Rupelian to middle Chattian; ∼28.8–23.25 Ma) corresponds to a decrease of clastic Alpine inputs throughout SE France caused by a reorganisation of the drainage network related with the exhumation of the southern External Crystalline Massifs. S3 highstand and S4 sequence (late Chattian to Aquitanian; from ∼23.25 Ma) correspond to the establishment of a longitudinal sediment routing system in the Rhône Valley, with material flowing southwards toward the Gulf of Lion, and supplied by the Palaeo-Isère to the north and potentially by the Palaeo-Durance to the south. This final stage in the reorganisation of the drainage network is clearly associated with the post-rift phase of the Gulf of Lion, which facilitated the opening of a new sink and the ultimate southward migration of the sedimentary area.

The Middle Jurassic Callovian Stage (∼165.2–160.8 Ma) represents a pivotal interval in Earth’s history marked by climate change, both warming and cooling (glacio-eustasy), widespread organic matter accumulation, and perturbations in the carbon cycle. On the Arabian Plate, this stage witnessed the initiation of intrashelf basins, large-scale coral–stromatoporoid reef growth, and a glacio-eustatic sea level fluctuation. Detailed global reconstructions are, however, hindered by discontinuous stratigraphic records, significant hiatuses, and a lack of integrated datasets. Here we present a synthesis of sedimentological, biostratigraphic, chemostratigraphic, and paleoenvironmental data from a well preserved and extended (290 m thick) carbonate-dominated Callovian succession in Saudi Arabia, which is continuously exposed along a >1000 km long escarpment. We integrate legacy datasets of dispersed reports and theses, produced during the mapping campaigns in the 1980s–1990s, with reinterpreted published carbon-isotope curves and a new sedimentological section, with refined calcareous nannofossil biostratigraphy, using modern taxonomy, standardized biozonation, and a Bayesian age model. The C-isotope curve shows an early Callovian positive δ13C excursion in the upper part of the gracilis Ammonoid Zone, followed by a negative shift at the base of the anceps Zone coinciding with siliciclastic influx from the Arabian shield. δ13C values rise through the Middle Callovian global warming with enhanced organic carbon burial on the Arabian Plate. The late Callovian cooling phase records extensive coral–stromatoporoid bioherms terminated by a sea-level fall near the Callovian–Oxfordian boundary. This work establishes the Arabian Plate as a key northern Gondwanan reference point for Callovian chronostratigraphy and calibration of global paleoceanographic, depositional, and climatic trends.

Despite the established role of bauxites as products of intense subaerial weathering, the provenance and formation processes of karst-type bauxite deposits remain poorly constrained due to the lack of systematic studies on modern analogues. To address this issue, we investigated the age, provenance, and formation processes of Quaternary bauxites in South China, which exhibit a complex provenance closely associated with modern fluvial sedimentation. Geochronological constraints indicate the formation age of the bauxite deposits to be between 439 ± 43 ka and 10.49 ± 0.78 ka (Middle Pleistocene to Early Holocene). Active bauxitization is interpreted to have taken place mainly during the Quaternary Ice Age. New UPb isotopic data for bauxites (n = 803) and river sediments (n = 455) reveal distinctly different provenance patterns between the two deposit types. Detrital zircons in river sediments display relatively uniform age distributions, indicating a stable fluvial regime characterized by sustained detrital input and transport with minimal influence from local bedrock sources. In contrast, bauxite deposits from the northern, central, and southern parts of central Guangxi show marked spatial variation in zircon age spectra. This variation demonstrates that Quaternary karst bauxites received episodic, short-range detrital inputs derived alternately from proximal igneous sources (e.g., ∼100-Ma granites) and more distal sedimentary sources. We interpret these patterns as the geochronological signature of alternating sheetflow and flood-driven inputs of weathering materials, followed by bauxitization under wet-dry climate oscillations paced by Quaternary glacial-interglacial cycles. This study provides the first modern, process-based framework for understanding how detrital supply, surface hydrology, and climate interact to produce karst bauxites, and it offers a valuable Quaternary analogue for interpreting deep-time bauxite systems, particularly Carboniferous-Permian deposits formed during the Late Paleozoic Ice Age.

This reply addresses the comments by Zhao on our article “A dataset and review of empirical estimation relationships for landslide runout distances.” We clarify that our study aimed to synthesize and update empirical approaches using observed runout distances, rather than to develop mechanistic models requiring explicit topographic confinement metrics. We also reiterate the acknowledged limitations of the available landslide inventories and outline directions for expanding the dataset in future work. Importantly, we note that our article did not claim to present a global or globally representative dataset, as implied in the comment.

During the middle and late Eocene, Asian terrestrial mammals dispersed to Europe, while primates and rodents dispersed across the 500-to-2000 km wide Neotethys Ocean and the 1500-to-2000 km wide Atlantic Ocean to colonize Afro-Arabia and South America. This study explores how these mammals have achieved such remarkable and enigmatic dispersals. We present high-resolution paleogeographic models for the middle to late Eocene based on updated plate kinematic reconstructions, paleo-bathymetry and paleo-topography data. With this, we evaluate landmass configurations and connectivity that may have facilitated faunal exchanges from Asia toward Europe, Afro-Arabia, and South America and discuss dispersal mechanisms between these biogeographic provinces. Our reconstructions reveal that during the Bartonian (∼40–38 Ma), an overland dispersal corridor between Asia and Balkanatolia became available to terrestrial mammals and acted as a pivotal pathway for Asian faunas dispersing toward western Europe and Afro-Arabia. We identified two Balkanatolian island-hopping routes across the Western Neotethys potentially enabling the dispersal of small-bodied Asian primates, rodents and artiodactyls to Afro-Arabia. Alternatively, these taxa may have rafted across the Central Neotethys. By ∼34 Ma, Balkanatolia fully connected with Western Europe, opening a southern “Grande Coupure” route for Asian faunas. In the Atlantic, we identify long-distance rafting as the most plausible mechanism for the 40–34 Ma transoceanic dispersal of the Asian-originated primates and rodents from Afro-Arabia to South America despite the likely presence of sparse islands along the Walvis Ridge and the Rio Grande Rise.
