Short summary
To assess whether current glacier loss in the Alps is unprecedented, we drilled ice cores from the Tödi summit glacier in Switzerland. We dated the ice with radionuclides and modelling, finding that the surface ice is from about 1960, and the deepest ice is 10,000 years old. Our results show that summit glaciers can preserve very old ice through warm periods, indicating local factors matter more than elevation, and some cold-based glaciers at risk of melting may preserve ancient climate data.

A low latitude-high altitude Alpine ice core record was obtained in 2011 from the glacier Alto dell’Ortles (Eastern Alps, Italy) and provided evidence of one of the oldest Alpine ice core records spanning the last ~7000 years, back to the last Northern Hemisphere Climatic Optimum. Here we provide a new Alto dell’Ortles chronology of improved accuracy that will allow to constrain Holocene climatic and environmental histories emerging from this high-altitude glacial archive of Central Europe.

Urban areas account for a substantial share of global greenhouse gas emissions, yet measuring these emissions precisely is challenging due to spatial variability. This study implemented an advanced laser measurement technique, to directly average this spatial variability by measuring over a 3.1 kilometer path, using only commercial parts. The high measurement precision and reliable operation, demonstrates that this technique is now accessible to the broader atmospheric measurement community.

Our study focused on understanding how a warming climate affects the Aletsch glacier accumulation area. We used multi-year radar measurements and direct firn‑core analyses to estimate changes in density, layering, and compaction of snow-to-ice over a year. Our results show that the upper layers of the glacier are changing faster due to stronger summer melt in the lower parts of the accumulation zone. Our findings help to improve firn densification models and glacier mass-balance estimation.

10Be is a radionuclide often measured in ice cores to reconstruct the solar magnetic field and geomagnetic field, as well as to date ice based on its half-life of 1.387 million years. Previous measurements in deep ice from Antarctica showed a decrease in concentrations with age. We analysed the influence of the sample preparation procedure and were able to show that the use of ion exchange columns can lead to decreasing concentrations, an effect which is amplified at greater depths and ages.

We mapped glacier outlines in Austria using recent, high resolution imagery. The resulting glacier inventory provides an update on glacier area in Austria in 2021-2023. More than 30% of glacier area was lost and 95 glaciers have disappeared since the mid-2000s. Glacier recession is accelerating and regular updates to glacier inventories are needed to understand downstream changes to the hydrological system, quantify glacier mass loss, and support planning and adaptation measures.

Water quality of lakes depends on deep convection. In many lakes, this is affected by thermobaricity, the temperature dependence of the compressibility of water. We created a numerical approach to demonstrate and emphasize the implementation of this effect in numerical lake models. We conceptually present the purely one dimensional thermobaric deep convection induced by denser water created by vertical cabbeling across the temperature of maximum density at a certain depth in the water column.

With this work, we provide important evidence that the Iron Hypothesis is less effective than originally thought in the Northern Hemisphere due to alkaline aerosol conditions. Therefore in the High-Nutrient Low-Chlorophyll North Pacific Ocean, other factors such as sea-ice extent or iron remobilization from sediments may have played a more relevant role than atmospheric iron fertilization in modulating marine primary productivity.

We analyse 8 samples from the East Greenland Ice-core Project (EGRIP) ice core, Greenland, using an underexplored method: single particle time of flight analysis. For the first time, we investigated thousands of particles from different climatic stages while applying a new approach to estimate particle sizes based on prior data. We characterise particles and clusters providing new insights on trace elements in ice sheets. This approach has enormous potential for analysing million-year-old ice.

Svalbard is ideal for studying how warming affects snow’s seasonal chemistry. By comparing the snow chemical composition of the 2019–2020 season with 2018–2019 and 2020–2021, we provide an overview of the seasonal and interannual variability of several chemical species on the Svalbard snowpack, furnishing insights into the interplay between short-term meteorological variability and the long-term climatic impacts of climate changes.

To avoid misinterpretation of impurity signals in ice cores, post-depositional changes need to be identified. Peak broadening with depth observed especially for S was previously related to diffusion in ice veins, but the exact physical mechanisms remain unclear. Our two-dimensional impurity maps by laser ablation inductively coupled plasma mass spectrometry were extended for the first time to S and Cl and support a view on diffusion not only through veins but also along grain boundaries.

Our research compares three systems of continuous flow analysis coupled with cavity ring-down spectrometry (CFA-CRD) from Venice, Paris, and Grenoble laboratories for measuring water isotopes in ice cores, crucial for reconstructing past climate. We quantify each system’s mixing and measurement noise effects, which impact the achievable resolution of isotope continuous records. Our findings reveal specific configurations and procedures to enhance measurement accuracy, providing a framework to optimise water isotope analysis.

Glacier albedo determines how much solar radiation is absorbed by the glacier surface and is a key driver of glacier melt. Alpine glaciers are losing their snow and firn cover, and the underlying darker ice is becoming exposed. This means that more solar radiation is absorbed by the ice, which leads to increased melt. To quantify these processes, we explore data from a high-elevation, on-ice weather station that measures albedo and combine this information with satellite imagery.

Glaciers in the Alps are receding at unprecedented rates. To understand how this affects the hydrology and ecosystems of the affected regions, it is important to measure glacier mass balance and ensure that records of field surveys are kept in standardized formats and well-documented. We describe glaciological measurements of ice ablation and snow accumulation gathered at Mullwitzkees and Venedigerkees, two glaciers in the Austrian Alps, since 2007 and 2012, respectively.

Understanding the behavior of ocean–atmosphere teleconnections in the North Pacific during warm intervals can aid in predicting future warming scenarios. However, majority ice core records from Alaska–Yukon region only provide data for the last few centuries. This study introduces a continuous chronology for Denali ice core from Begguya, Alaska, using multiple dating methods. The early-Holocene-origin Denali ice core will facilitate future investigations of hydroclimate in the North Pacific.

We present new data from a 10 m ice core drilled in 2019 and a 8.4 m parallel ice core drilled in 2021 at the summit of Weißseespitze glacier. In a new combination of proxies, we discuss profiles of stable water isotopes, major ion chemistry as well as a full profile of microcharcoal and levoglucosan. We find that the chemical and isotopic signals are preserved, despite the ongoing surface mass loss. This is not be to expected considering what has been found at other glaciers at similar locations.

We investigate how a 250-year history of the emission of air pollutants (major inorganic aerosol constituents, black carbon, and trace species) is preserved in ice cores from four sites in the European Alps. The observed uniform timing in species-dependent longer-term concentration changes reveals that the different ice-core records provide a consistent, spatially representative signal of the pollution history from western European countries.

The rock glacier in Äußeres Hochebenkar (Austria) moved faster in 2021–2022 than it has in about 70 years of monitoring. It is currently destabilizing. Using a combination of different data types and methods, we show that there have been two cycles of destabilization at Hochebenkar and provide a detailed analysis of velocity and surface changes. Because our time series are very long and show repeated destabilization, this helps us better understand the processes of rock glacier destabilization.

This study proposes a quantitative method to reconstruct annual precipitation records at the millennial timescale from the Tibetan ice cores through combining annual layer identification based on LA-ICP-MS measurement with an ice flow model. The reliability of this method is assessed by comparing our results with other reconstructed and modeled precipitation series for the Tibetan Plateau. The assessment shows that the method has a promising performance.

We present a methodology that reduces the chronological uncertainty of an Alpine ice core record from the glacier Alto dell’Ortles, Italy. This chronology will allow the constraint of the Holocene climatic and environmental histories emerging from this archive of Central Europe. This method will allow to obtain accurate chronologies also from other ice cores from-low latitude/high-altitude glaciers that typically suffer from larger dating uncertainties compared with well dated polar records.

Eastern Alpine glaciers have been receding since the Little Ice Age maximum, but until now the majority of glacier margins could be delineated unambiguously. Today the outlines of totally debris-covered glacier ice are fuzzy and raise the discussion if these features are still glaciers. We investigated the fate of glacier remnants with high-resolution elevation models, analyzing also thickness changes in buried ice. In the past 13 years, the 46 glaciers of Silvretta lost one-third of their area.

In our study we dated a 46 m deep ice core retrieved from the Adamello glacier (Central Italian Alps). We obtained a timescale combining the results of radionuclides 210Pb and 137Cs with annual layer counting derived from pollen and refractory black carbon concentrations. Our results indicate that the surface of the glacier is older than the drilling date of 2016 by about 20 years, therefore revealing that the glacier is at high risk of collapsing under current climate warming conditions.

Short summary
This study presents an age profile of the summit glacier of Weißseespitze in the Austrian Alps. The ages were obtained by combining 14C dating with the novel atom trap trace analysis for 39Ar. The data was used to constrain glacier age models. The results show that the surface ice is ~400 a old due to recent ice loss. The remaining ice continuously covers ages up to 6000 a. This work underscores the utility of 39Ar dating in glaciology, enabling precise reconstruction of age-depth relationships.
