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.

Drillings, outcrops, and seismic data provide insights into a glacial basin and a former river channel in northern Switzerland. Both are infilled with diverse (glacial, lacustrine, fluvial, colluvial) sediments attributed to three separate glaciations. The depth of the glacial basin depends strongly on the underlying rock type, which together with (hydro)fractures provides evidence on the conditions and erosion processes at the ice–rock interface.

Short summary
Previous reconstructions conclude that the southern Black Forest, south-west Germany, temporarily hosted four ice caps during the Late Pleistocene (129 000–11 700 years before present). This work reviews existing studies on glacial landforms north-east of its highest summit, Feldberg (1493 m above sea level), in the light of new observations. Whilst this study largely confirms previous work, we reject and newly describe several glacial landforms.

The subdivision and distinction of gravel units is an important tool in terrestrial Quaternary stratigraphy but can be challenging. Here, we investigate the glaciofluvial infill of the Upper Rhine Graben as an archive of recurring Alpine glaciations. With the help of statistical approaches, we identify differences in petrographic compositions, thereby differentiating two units that are likely representative of the last and penultimate glaciation, which have previously been difficult to pinpoint.

The Mühlbach series has been given as evidence for a Late Pliocene/Early Pleistocene Aare–Rhine fluvial system in northern Switzerland and southwest Germany. We show that these deposits represent a variety of different units. At the type location, luminescence dating indicates an age of 55 ka, and we interpret the deposits as slope reworking. Beside methodological implications, our studies recommend caution regarding the interpretation of stratigraphic units for which limited data are available.

In the frame of the DOVE (Drilling Overdeepened Alpine Valleys) project and with the support of the International Continental Scientific Drilling Program (ICDP), we drilled and recovered a 252 m long sediment core from the Basadingen Through. The Basadingen Trough, once eroded by the Rhine glacier during several ice ages, reaches over 300 m under the modern landscape. The sedimentary filling represents a precious scientific archive for understanding and reconstructing past glaciations.

Geoscientists working with drill cores often struggle with proper photo documentation. We present a simple smartphone-based setup for acquiring high-resolution undistorted core pictures as an alternative to state-of-the-art commercial line scan imaging systems that are typically expensive and inflexible. It makes use of the phone's panoramic picture mode while being guided along the core in question on a rail, and the resulting images are of similar quality to classic line scan photos.

The geothermal carbonate reservoir below Munich, Germany, is extremely heterogeneous because it is controlled by many factors like lithology, diagenesis, karstification, and tectonic deformation. We used a 3D seismic single- and multi-attribute analysis combined with well data and a neural-net-based lithology classification to obtain an improved reservoir concept outlining its structural and diagenetic evolution and to identify high-quality reservoir zones in the Munich area.

Lake Petén Itzá, northern Guatemala, is one of the oldest lakes in the northern Neotropics. In this study, we analyzed geochemical and mineralogical data to decipher the hydrological response of the lake to climate and environmental changes between 59 and 15 cal ka BP. We also compare the response of Petén Itzá with other regional records to discern the possible climate forcings that influenced them. Short-term climate oscillations such as Greenland interstadials and stadials are also detected.

The loess sequence of Köndringen, Upper Rhine Graben, comprises several glacial–interglacial cycles. It has been investigated using a multi-method approach including the measurement of colour, grain size, organic matter, and carbonate content. The analyses reveal that the sequence comprises several fossil soils and layers of reworked soil material. According to luminescence dating, it reaches back more than 500 000 years.

Erosion processes below glacier ice have carved large and deep basins in the landscapes surrounding mountain ranges as well as polar regions. With our comparison, we show that these two groups of basins are very similar in their shapes and sizes. However, open questions still remain especially regarding the sediments that later fill up these basins. We aim to stimulate future research and promote exchange between researchers working around the Alps and the northern central European lowlands.

The dissolution of rocks poses a severe hazard because it can cause subsidence and sinkhole formation. Based on results from our study area in Thuringia, Germany, using P- and SH-wave reflection seismics, electrical resistivity and electromagnetic methods, and gravimetry, we develop a geophysical investigation workflow. This workflow enables identifying the initial triggers of subsurface dissolution and its control factors, such as structural constraints, fluid pathways, and mass movement.

Short summary
Previous glaciations eroded below the ice deep valleys in the Alpine foreland, which, with their sedimentary fillings, witness the timing and extent of these glacial advance–retreat cycles. Drilling such sedimentary sequences will thus provide well-needed evidence in order to reconstruct the (a)synchronicity of past ice advances in a trans-Alpine perspective. Eventually these data will document how the Alpine foreland was shaped and how the paleoclimate patterns varied along and across the Alps.

We used a combination of remote sensing, field investigations, and laboratory analysis to map and characterize abandoned river channels within the French Upper Rhine alluvial plain. Our results show five major paleochannel groups with significant differences in their pattern, morphological characteristics, and sediment filling. The formation of these paleochannel groups is attributed to significant changes in environmental processes in the area during the last ~ 11 700 years.

Short summary
A loess sequence in SW Germany was investigated using a high-resolution multi-method approach. It dates to 34–27 ka and comprises layers of initial soil formation. Drier conditions and a different atmospheric circulation pattern during the time of deposition are expected as the soil layers are less strongly developed compared to similar horizons further north. Dust accumulation predates the last advance of Alpine glaciers, and no loess deposition is recorded for the time of maximum ice extent.

We used a two-step approach with limited sampling effort in existing storm water infrastructure to illustrate the risk of biocide emission in a 2 ha urban area 13 years after construction had ended. First samples at a swale confirmed the overall relevance of biocide pollution. Then we identified sources where biocides were used for film protection and pathways where transformation products were formed. Our results suggest that biocide pollution is a also continuous risk in aging urban areas.

Hipercorig is a new modular lake sediment coring instrument based on a barge and a hydraulic corer system driven by a down-the-hole hammer. Hipercorig's performance was tested on the two periglacial lakes, namely Mondsee and Constance, located on the northern edge of the Alpine chain. Up to 63 m of Holocene lake sediments and older meltwater deposits from the last deglaciation were recovered for the first time.

In our work, we carry out an in-depth structural analysis of a geometrically decoupled fault system in the southern German Molasse Basin using a high-resolution 3-D seismic dataset. Based on this analysis, we reconstruct the tectonic history and changes in the stress regimes to explain the structure and evolution of faults. The results contribute in understanding the driving mechanisms behind formation, propagation, and reactivation of faults during foreland basin formation.

Luminescence properties of samples from the Rinikerfeld, northern Switzerland, are assessed. Reader-specific low preheat temperatures are invesigated to ensure suitable measurement conditions. While quartz is found to be dominated by stable fast components, signal loss is observed for feldspar and polymineral. In general, the ages of the fading corrected feldspar and the fine-grained polymineral fractions are in agreement with coarse-grained quartz, and ages indicate sedimentation during MIS6.

Short summary
The Tannwald Basin, explored by drilling and formed by repeated advances of the Rhine Glacier, reveals key geological insights. Ice-contact sediments and evidence of deformation highlight gravitational and glaciotectonic processes. ICDP DOVE 5068_1_C core data define lithofacies associations, reflecting basin infill cycles, marking at least three distinct glacial advances. Integrating these findings aids understanding the broader glacial evolution of the Lake Constance amphitheater.
