Short summary
This study examines the evolution of the lower Bruche River valley in north-eastern France through its fluvial terraces, reflecting past river dynamics and environmental changes. Terrace formations are dated using luminescence to ~ 12–14 ka, ~ 27–35 ka, and at least 200 ka. Methodological improvements over conventional luminescence dating techniques are also discussed and refined in this study.

The work shows detailed reconstructions of the glaciers in the Valsugana area (south-eastern Alps) during the Last Glacial Maximum (LGM) and is supported by robust evidence and new exposure datings. These are the first ages for the internal sector of the south-eastern Alps. Local glaciers not connected with the major ice network were used for the calculation of their equilibrium line altitude. This let us estimate LGM palaeoprecipitation and compare it to Alpine palaeoclimatological models.

By measuring the radioactive decay of atmospherically produced 36Cl and 10Be in an ice core drilled in West Antarctica, we were able to determine the age of the deepest sample close to bedrock to be about 550 thousand years old. This means that the ice in this location, known as Skytrain Ice Rise, has survived several warm periods in the past, at least since marine isotope stage 11.

Our study examines erosion in a small, pre-Alpine basin by using cosmogenic nuclides in river sediments. Based on a dense measuring network we were able to distinguish two main zones: an upper zone with slow erosion of surface material, and a steeper, lower zone where faster erosion is driven by landslides. The data suggests that sediment has been constantly produced over thousands of years, indicating a stable, long-term balance between contrasting erosion processes.

Pediments are long flat surfaces that extend outwards from the foot of mountains; within South Africa they are regarded as ancient landforms that can give key insights into landscape and mantle dynamics. Cosmogenic nuclide dating has been incorporated with geological (soil formation) and geomorphological (river incision) evidence, which shows that the pediments are long-lived features beyond the ages reported by cosmogenic nuclide dating.

Here we used the anthropogenic radionuclides I-129 and U-236 as tracers for Atlantic Water circulation in the Arctic Ocean. New data collected in 2021 allowed to assess the distribution of Atlantic Water and mixing with Pacific-origin water in the surface layer in that year. By using historical tracer data from 2011 to 2021, we looked into temporal changes of the circulation and found slightly older waters in the central Arctic Ocean in 2021 compared to 2015.

In this study, we test the use of excess meltwater from continuous flow analysis from a firn core from Greenland for the measurement of 10Be for solar activity reconstructions. We show that the quality of results is similar to the measurements on clean firn, which opens the possibility to obtain continuous 10Be records without requiring large amounts of clean ice. Furthermore, we investigate the possibility of identifying solar storm signals in 10Be records from Greenland and Antarctica.

Valleys in the Alps are shaped by glaciers, rivers, mass movements, and slope processes. An understanding of such processes is of great importance in hazard mitigation. We focused on the evolution of the Frébouge cone, which is composed of glacial, debris flow, rock avalanche, and snow avalanche deposits. Debris flows started to form the cone prior to ca. 2 ka ago. In addition, the cone was overrun by a 10 Mm3 large rock avalanche at 1.3 ± 0.1 ka and by the Frébouge glacier at 300 ± 40 a.

The record of past climate is preserved by several archives from different regions, such as ice cores from Greenland or Antarctica or speleothems from caves such as the Hulu Cave in China. In this study, these archives are aligned by taking advantage of the globally synchronous production of cosmogenic radionuclides. This produces a new perspective on the global climate in the period between 20 000 and 25 000 years ago.

We present an age scale for a new ice core drilled at Skytrain Ice Rise, an ice rise facing the Ronne Ice Shelf in Antarctica. Various measurements in the ice and air phases are used to match the ice core to other Antarctic cores that have already been dated, and a new age scale is constructed. The 651 m ice core includes ice that is confidently dated to 117 000–126 000 years ago, in the last interglacial. Older ice is found deeper down, but there are flow disturbances in the deeper ice.

We constrained deposition phases of fluvial sediments (NE Belgium) over the last 1 Myr with analysis and modelling of rare isotopes accumulation within sediments, occurring as a function of time and inverse function of depth. They allowed the determination of three superposed deposition phases and intercalated non-deposition periods of ~ 40 kyr each. These phases correspond to 20 % of the sediment age, which highlights the importance of considering deposition phase when dating fluvial sediments.

We apply quartz 3He paleothermometry along two deglaciation profiles in the European Alps to reconstruct temperature evolution since the Last Glacial Maximum. We observe a 3He thermal signal clearly colder than today in all bedrock surface samples exposed prior the Holocene. Current uncertainties in 3He diffusion kinetics do not permit distinguishing if this signal results from Late Pleistocene ambient temperature changes or from recent ground temperature variation due to permafrost degradation.

Short summary
Glacial and non-glacial processes have left a strong imprint on the landscape of the European Alps, but further research is needed to better understand their long-term effects. We apply a new technique combining two methods for bedrock surface dating to calculate post-glacier erosion rates next to a Swiss glacier. Interestingly, the results suggest non-glacial erosion rates are higher than previously thought, but glacial erosion remains the most influential on landscape evolution.

Continuous observations and measurements from high elevations are necessary to monitor recent climate and environmental changes in the tropical mountains of eastern Africa, but meteorological and ground temperature data from above 3000 m are very rare. Here we present a comprehensive ground temperature monitoring network that has been established between 3493 and 4377 m in the Bale Mountains (Ethiopian Highlands) to monitor and study the afro-alpine climate and ecosystem in this region.

A scientific drilling was conducted into a bedrock trough (overdeepening) in Bern-Bümpliz (Switzerland) in an effort to advance the knowledge of the Quaternary prior to 150 000 years ago. We encountered a 208.5 m-thick succession of loose sediments (gravel, sand and mud) in the retrieved core and identified two major sedimentary sequences (A: lower, B: upper). The sedimentary suite records two glacial advances and the subsequent filling of a lake sometime between 300 000 and 200 000 years ago.

Small mountain glaciers advance and recede as a response to summer temperature changes. Dating of glacial landforms with cosmogenic nuclides allowed us to reconstruct the advance and retreat history of an Alpine glacier throughout the past ~ 11 000 years, the Holocene. The results contribute knowledge to the debate of Holocene climate evolution, indicating that during most of this warm period, summer temperatures were similar to or warmer than in modern times.

Large sorted stone stripes have been discovered on the 4000 m high central Sanetti Plateau of the tropical Bale Mountains in Ethiopia. The stripes are a mystery as similar landforms have so far only been reported in the temperate zone and polar regions. Our investigations suggest that the stripes formed in the vicinity of a former ice cap on the plateau during a much colder climatic period. The distinct pattern is the result of a process related to cyclic freezing and thawing of the ground.

Atlantic Water that carries heat and anthropogenic carbon into the Arctic Ocean plays an important role in the Arctic sea-ice cover decline, but its pathways and travel times remain unclear. Here we used two radionuclides of anthropogenic origin (129I and 236U) to track Atlantic-derived waters along their way through the Arctic Ocean, estimating their travel times and mixing properties. Results help to understand how future changes in Atlantic Water properties will spread through the Arctic.

Orakei Basin – a former maar lake in Auckland, New Zealand – provides an outstanding sediment record over the last ca. 130 000 years, but an age model is required to allow the reconstruction of climate change and volcanic eruptions contained in the sequence. To construct a relationship between depth in the sediment core and age of deposition, we combined tephrochronology, radiocarbon dating, luminescence dating, and the relative intensity of the paleomagnetic field in a Bayesian age–depth model.

Short summary
Alpine landscapes are transformed by several erosion processes. 10Be concentrations measured in river sediments at the outlet of a basin represent a powerful tool to quantify how fast the catchment erodes. We measured erosion rates within the Dora Baltea catchments (western Italian Alps). Our results show that erosion is governed by topography, bedrock resistance and glacial imprint. The Mont Blanc massif has the highest erosion and therefore dominates the sediment flux of the Dora Baltea river.
Alpine landscapes are transformed by several erosion processes. 10Be concentrations measured in...
