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.

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.

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.

Soil compaction resulting from inappropriate agricultural practices affects soil ecological functions, decreasing the water-use efficiency of plants. Recent developments contributed to innovative sensing approaches aimed at safeguarding soil health. Here, we explored how the most used geophysical methods detect soil compaction. Results, validated with traditional characterization methods, show the pros & cons of both non-invasive techniques and their ability to characterize compacted areas.

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.

Pseudo-relict rock glaciers look visually 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 the 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 ~30 % of the ice stored in the rock glaciers in the study area.

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.

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.

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.

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.

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.

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. A case study is presented regarding an orange orchard in Sicily.

We monitor ground temperature, water pressure, and relative ice/water contents in a creeping ice-rich rock glacier in mountain permafrost to study its characteristics during a deceleration period with dry conditions and a summer heat wave. The snowpack has an important role as a provider of water and as a thermal insulator. Snow-poor winters, followed by dry summers, induce cooling and drying of the permafrost, leading to rock glacier deceleration.

Number of high-altitude streams with high concentrations of toxic elements (Al, F, Mn, Ni) due to pyrite weathering and sulfuric acid production is increasing in the Eastern Alps. In contact of sulfuric acid, these elements are released from rocks and stored in ice in rock glaciers. Today, climate change accelerates rock glacier ice melt which leads to a quick and focused element export in summer. Our research tries to assess consequences of accelerated rock glacier melt on streamwater quality.

Permafrost (permanently frozen soil at depth) is thawing as a result of climate change. However, estimating its future degradation is particularly challenging due to the complex multi-physical processes involved. In this work, we designed and ran numerical simulations for months on a supercomputer to quantify the impact of climate change in a forested valley of Central Siberia. There, climate change could increase the thickness of the seasonally thawed soil layer in summer by up to 45 % by 2100.

In view of water scarcity in the Andes, the significance of permafrost as a future water resource is often debated focusing on satellite-detected features such as rock glaciers. We present data from > 50 geophysical surveys in Chile and Argentina to quantify the ground ice volume stored in various permafrost landforms, showing that not only rock glacier but also non-rock-glacier permafrost contains significant ground ice volumes and is relevant when assessing the hydrological role of permafrost.

To investigate the effect of groundwater flow on the active layer on slopes in permafrost landscapes, we conducted several modeling experiments. We find that groundwater moving downslope in the subsurface causes areas uphill to be warmer than downhill. This effect is explained by differences in heat capacity, conductivity, and infiltration. Therefore, in a changing climate, higher soil moisture could have a cooling effect on the active layer and attenuate warming from higher air temperatures.

Polygon-shaped landforms present in relatively flat Arctic tundra result in complex landscape-scale water drainage. The drainage pathways and the time to transition from inundated conditions to drained have important implications for heat and carbon transport. Using fundamental hydrologic principles, we investigate the drainage pathways and timing of individual polygons, providing insights into the effects of polygon geometry and preferential flow direction on drainage pathways and timing.

This paper outlines the results from laboratory tests of soil freezing impacts on infiltration rates, hydraulic conductivity, and soil pore distribution characteristics. The results indicated that macropores (> 5 mm) accounted for < 1 % of the pore-volume-contributed half of the flow in unfrozen conditions and that the freezing of macropores resulted in considerable decreases in hydraulic conductivity. The results should be of interest for cold region hydrology in general.

Groundwater is an underappreciated catalyst of environmental change in a warming Arctic. We provide evidence of how changing groundwater systems underpin surface changes in the north, and we argue for research and inclusion of cryohydrogeology, the study of groundwater in cold regions.

Methane stored below permafrost is an unknown quantity in the Arctic greenhouse gas budget. In coastal areas with rising sea levels, much of the methane seeps into the sea and is removed before it reaches the atmosphere. However, where land uplift outpaces rising sea levels, the former seabed freezes, pressurising methane-rich groundwater beneath, which then escapes via permafrost seepages called pingos. We describe this mechanism and the origins of the methane discharging from Svalbard pingos.

Short summary
Widely-used land models project near-surface drying of the terrestrial Arctic despite increases in the net water balance driven by climate change. Drying was generally associated with increases of active-layer depth and permafrost thaw in a warming climate. However, models lack important mechanisms such as thermokarst and soil subsidence that will change the hydrological regime and add to the large uncertainty in the future Arctic hydrological state and the associated permafrost carbon feedback.

Short summary
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.
