In the last decades, geochemical investigations at the springs of rock glaciers have been used to estimate their drainage processes, and the frozen layer is typically considered to act as an aquiclude or aquitard. In this work, we evaluated the hydraulic behavior of a mountain permafrost site by executing a geophysical monitoring experiment. Several hundred liters of salt water have been injected into the subsurface, and geoelectrical measurements have been performed to define the water flow.

This paper presents TOPMELT, a parsimonious snowpack simulation model integrated into a basin-scale hydrological model. TOPMELT implements the full spatial distribution of clear-sky potential solar radiation by means of a statistical representation: this approach reduces computational burden, which is a key potential advantage when parameter sensitivity and uncertainty estimation procedures are carried out. The model is assessed by examining different resolutions of its domain.

We propose a sub-seasonal timescale based on pollen analyses for a Mt. Ortles firn core. The method can be applied to all types of glaciers, provided the proximity of the pollen source and a negligible time lag between pollen production and its deposition on the glacier. By combining pollen dating with a mass balance model we found evidence that pollen grains are resilient to downward transport by percolating water and that pollen shows a high potential for inferring past climatic conditions.

Snow water equivalent is an important parameter for hydrological and climate change studies, however its measurement is tedious and time consuming. In this paper we show that it is possible to accurately measure snow water equivalent using electromagnetic methods. During a field campaign we tested the performances of traditional methods vs. those of a Ground Penetrating Radar, founding a very good agreement between the snow water equivalent values computed with the two different methods.

New ice cores were extracted from Alto dell'Ortles, the highest glacier of South Tyrol in the Italian Alps, to check whether prehistoric ice, which is coeval to the famous 5300-yr-old Tyrolean Iceman, is still preserved in this region. Dating of the ice cores confirms the hypothesis and indicates the drilling site has been glaciated since the end of the Northern Hemisphere Climatic Optimum (7000 yrs BP). We also infer that an unprecedented acceleration of the glacier flow has recently begun.

We investigated the applicability of the SfM–MVS approach for calculating the geodetic mass balance of a glacier and for the detection of the surface displacement rate of an active rock glacier located in the eastern Italian Alps. The results demonstrate that it is possible to reliably quantify the investigated glacial and periglacial processes by means of a quick ground-based photogrammetric survey that was conducted using a consumer grade SRL camera and natural targets as ground control points.

This work analyses the longer mass balance series of Italian glaciers. All glaciers experienced mass loss in the observation period, with increasing mass loss rates mainly due to increased ablation during longer and warmer ablation seasons. Low-altitude glaciers with low range of elevation are more out of balance than the higher, larger and steeper glaciers, which maintain accumulation areas. Because most of the monitored glaciers are at risk of extinction, they require a soon replacement.

Using a dataset from 12 weather stations collected in 2010 and 2011, we analyzed the air temperature variability and wind regime over three different glaciers in the Ortles-Cevedale. The magnitude of the cooling effect and the occurrence of katabatic boundary layer processes showed remarkable differences among the three ice bodies, suggesting the likely existence of important reinforcing mechanisms during glacier decay and fragmentation, with significant impacts for glacier mass balance modeling.

This study describes a unique large-scale isotope dataset to study water dynamics in European forests. Researchers collected data from 40 beech and spruce forest sites in spring and summer 2023, using a standardized method to ensure consistency. The results show that water sources for trees change between seasons and vary by tree species. This large dataset offers valuable information for understanding plant water use, improving ecohydrological models, and mapping water cycles across Europe.

Reversal polarity is observed in rock glacier seismic refraction tomography. We collected several datasets observing this phenomenon in Switzerland and Italy. This phase change may be linked to interferences due to the presence of a thin low-velocity layer. Our results are confirmed by the modelling and analysis of synthetic seismograms to demonstrate that the presence of a low-velocity layer produces a polarity reversal on the seismic gather.

We show that Icelandic long-runout landslides with longitudinal ridges represent good analogues of Martian landforms. The large record of long-runout landslides with longitudinal ridges emplaced after the Last Glacial Maximum in Iceland offers a unique opportunity to study the possible relation between the development of these landforms and environmental conditions. This could have implications for reconstructing Martian paleoclimatic and paleoenvironmental conditions.

Our paper concerns the use of a dense network of low-cost seismic accelerometers in populated areas to achieve rapid and reliable estimation of exposure maps in Trentino (northeast Italy). These additional data, in conjunction with the automatic monitoring procedure, allow us to obtain dense measurements which only rely on actual recorded data, avoiding the use of ground motion prediction equations. This leads to a more reliable picture of the actual ground shaking.

What drives young water fraction, F*yw (i.e., the fraction of water in streamflow younger than 2–3 months), variations with elevation? Why is F*yw counterintuitively low in high-elevation catchments, in spite of steeper topography? In this paper, we present a perceptual model explaining how the longer low-flow duration at high elevations, driven by the persistence of winter snowpacks, increases the proportion of stored (old) water contributing to the stream, thus reducing F*yw.

A new combination of temperature, water pressure and cross-borehole electrical resistivity data is used to investigate ice/water contents in an ice-rich rock glacier. The landform is close to 0°C and has locally heterogeneous characteristics, ice/water contents and temperatures. The techniques presented continuously monitor temporal and spatial phase changes to a depth of 12 m and provide the basis for a better understanding of accelerating rock glacier movements and future water availability.

The Ice Memory project aims to extract, analyze, and store ice cores from worldwide retreating glaciers. One of the selected sites is the last remaining ice body in the Apennines, the Calderone Glacier. To assess the most suitable drilling position, geophysical surveys were performed. Reliable ground penetrating radar measurements have been positively combined with a geophysical technique rarely applied in glacier environments, the Frequency Domain Electro-Magnetic prospection.

We analyzed the variability in the isotopic composition of plant water extracted by two different methods, i.e., cryogenic vacuum distillation (CVD) and Scholander-type pressure chamber (SPC). Our results indicated that the isotopic composition of plant water extracted by CVD and SPC was significantly different. We concluded that plant water extraction by SPC is not an alternative for CVD as SPC mostly extracts the mobile plant water whereas CVD retrieves all water stored in the sampled tissue.

The use of non-invasive geophysical imaging of root system processes is of increasing interest to study soil–plant interactions. The experiment focused on the behaviour of grapevine plants during a controlled infiltration experiment. The combination of the mise-à-la-masse (MALM) method, a variation of the classical electrical tomography map (ERT), for which the current is transmitted directly into the stem, holds the promise of being able to image root distribution.

Understanding how water flows through ecosystems is needed to provide society and policymakers with the scientific background to manage water resources sustainably. Stable isotopes of hydrogen and oxygen in water are a powerful tool for tracking water fluxes, although the heterogeneity of natural systems and practical methodological issues still limit their full application. Here, we examine the challenges in this research field and highlight new perspectives based on interdisciplinary research.

The paper presents an integrated approach to monitoring root water uptake and link this information to the plant transpiration measured by sap flow and eddy covariance. The monitoring of soil conditions is achieved using 3-D electrical resistivity tomography. This ensemble of data can be used jointly to model the soil-plant interactions and identify the extent and efficiency of the root zone in front of existing irrigation schemes.

In this study, we apply an electrical method in a high-mountain permafrost terrain in the Italian Alps, where long-term borehole temperature data are available for validation. In particular, we investigate the frequency dependence of the electrical properties for seasonal and annual variations along a 3-year monitoring period. We demonstrate that our method is capable of resolving temporal changes in the thermal state and the ice / water ratio associated with seasonal freeze–thaw processes.

Permafrost conditions of the East Siberian Mountains are poorly known because of the severe climate, extreme terrain, and farness and scarcity of data. The ground temperature regime plays a key role in mountainous regions, influencing the environment, slope stability, geomorphological processes and hydrological processes. We present the results of recent examinations of the permafrost thickness variations, temperature regime of thaw zones (taliks) and permafrost of the Suntar-Khayata Range.

A new combination of temperature, water pressure and cross-borehole electrical resistivity data is used to investigate ice/water contents in an ice-rich rock glacier. The landform is close to 0°C and has locally heterogeneous characteristics, ice/water contents and temperatures. The techniques presented continuously monitor temporal and spatial phase changes to a depth of 12 m and provide the basis for a better understanding of accelerating rock glacier movements and future water availability.

We extend the application of electrical methods to characterize alpine permafrost using the so-called induced polarization (IP) effect associated with the storage of charges at the interface between liquid and solid phases. We investigate different field protocols to enhance data quality and conclude that with appropriate measurement and processing procedures, the characteristic dependence of the IP response of frozen rocks improves the assessment of thermal state and ice content in permafrost.

We presented a geophysical study of one intact and one relict rock glacier in semi-arid Chile. The interpretation of the collected data through different methods identifies geophysical signature differences between the two rock glaciers and characterizes their subsurface structure and composition. This is of great importance because of rock glaciers' relevant role in freshwater production, transfer and storage, especially in this area of increasing human pressure and high rainfall variability.

This study investigated a cave in Utah (USA) that contains a deposit of perennial ice. Such ice caves are important sources of information about past climate and are currently threatened by rising temperatures. The origin (precipitation), thickness (3 m), and age (several centuries) of the ice were constrained by a variety of methods. Liquid water recently entered the cave for the first time in many years, suggesting a destabilization of the cave environment.

Short summary
The active layer, a buffer between permafrost and the atmosphere, is more sensitive and responds more quickly to climate change. How the freeze–thaw action at different stages regulates carbon emissions is still unclear. We conducted 2-year continuous in situ measurements in an alpine meadow permafrost ecosystem in the Qinghai–Tibet Plateau and found the freeze–thaw process modified the Rs dynamics differently in different stages. Results suggest great changes in freeze–thaw process patterns.

Short summary
Pseudo-relict rock glaciers look relict but contain patches of permafrost. They are poorly known in terms of permafrost content, spatial distribution and frequency. Here we use spring-water temperature for a preliminary estimate of the permafrost presence in rock glaciers of a 795 km2 catchment in the Italian Alps. The results show that ~50 % of rock glaciers classified as relict might be pseudo-relict and might contain ~20 % of the ice stored in the rock glaciers in the study area.
