We measured concentrations of fallout radionuclides (FRNs) in soil samples taken from arable land in South Africa. We find that during the second half of the 20th century CE, the FRN data strongly correlate with the soil organic matter (SOM) content of the soils. The finding implies that wind erosion strongly influenced SOM loss in the soils we investigated. Furthermore, the exponential decline of FRN concentrations and SOM content over time peaks shortly after native grassland is cultivated.

We present our model ChronoLorica. We coupled the original Lorica model, which simulates soil and landscape evolution, with a geochronological module that traces cosmogenic nuclide inventories and particle ages through simulations. These properties are often measured in the field to determine rates of landscape change. The coupling enables calibration of the model and the study of how soil, landscapes and geochronometers change under complex boundary conditions such as intensive land management.

Understanding how vegetation might respond to climate change is especially important in arctic–alpine ecosystems, where major shifts in shrub growth have been observed. We studied how such changes come to pass and how future changes might look by measuring hourly variations in the stem diameter of dwarf shrubs from one common species. From these data, we are able to discern information about growth mechanisms and can thus show the complexity of shrub growth and micro-environment relations.

We develop in situ-produced terrestrial cosmogenic krypton as a new tool to date and quantify Earth surface processes, the motivation being the availability of six stable isotopes and one radioactive isotope (81Kr, half-life 229 kyr) and of an extremely weathering-resistant target mineral (zircon). We provide proof of principle that terrestrial Krit can be quantified and used to unravel Earth surface processes.

Short summary
The Last Glacial Maximum (LGM) about 21 kyr ago is known to have been global in extent. Nonetheless, we have limited knowledge during the pre-LGM time in the southern middle latitudes. If we want to understand the causes of the ice ages, the complete glacial period must be addressed. In this paper, we show that the Patagonian Ice Sheet in southern South America reached its full glacial extent also by 57 kyr ago and defies a climate explanation.

In this study, we comprehensively test a method to derive soil densities under fieldwork conditions. The method is mainly based on images taken from consumer-grade cameras. The obtained soil/sediment densities reflect
truevalues by generally > 95 %, even if a smartphone is used for imaging. All computing steps can be conducted using freeware programs. Soil density is an important variable in the analysis of terrestrial cosmogenic nuclides, for example to infer long-term soil production rates.

Geomorphological mapping and analysis conducted as an initial step towards a future sediment budget study of the middle Waimakariri River (Southern Alps, New Zealand) reveals that the traditional concept of the temporary palaeolake
glacial Lake Speightis conflicting with our conclusions of realistic chronosequences and timescales of para- and postglacial landform development. Especially the temporal and causal relation to the last deglaciation needs to be questioned and will be discussed.

The chronostratigraphy of the Rhine’s main terrace along the Middle Rhine Valley (MRV) is poorly constrained. This study fills this gap by using electron spin resonance (ESR) dating of quartz grains collected from the famous Kärlich site. Consistent ESR results date this terrace to ~1.5 Ma and have far-reaching implications as they numerically constrain, for the first time, the aggradation time of key terrace deposits along the MRV, providing new insights into the Rhine’s Quaternary evolution.

This study aims to reconstruct the last glaciation of the southern Black Forest. Ice-marginal positions in this region were, for the first time, directly dated. Glacier retreat from the last glaciation maximum position was probably underway no later than 21 ka. Re-advances and/or standstills of glaciers (no later than 17–16 ka, 15–14 ka and 13 ka) punctuated the subsequent trend towards ice-free conditions.

Short summary
Geological glacial features such as moraines can be used to construct the environment of former times. While sands may indicate colder phases, soils and peat preserved witness warm phases. Using various dating techniques, the ages of such features can be obtained. This is important in order to get an understanding of the climate of the past, in this study on the extent of the ice marginal position in Schleswig-Holstein.

Short summary
Comparing quartz optically stimulated luminescence (OSL) and fine-grain post-infrared infrared stimulated luminescence (pIRIR) ages, agreement was largely found, e.g. the bracketing of the L1SS1 pedocomplex to ca. 30–40 ka. Nevertheless some age differences between the Bayreuth (OSL) and the Gliwice (pIRIR) data invite further discussion. Exact dating using various protocols and grain sizes remains challenging, in particular for a periglacial environment with strong heterogeneity of material.

The presented doctoral dissertation uses luminescence dating techniques to reconstruct the past environmental and climatic conditions in the middle and lower Danube basin during the period of Homo sapiens' emergence in Europe. The methodological approach focused on optically stimulated luminescence dating of loess deposits, but for some the sections the geochronological methods were combined with physical, biological and geochemical proxy data to reconstruct the paleoenvironmental conditions.

Short summary
Deposits related to the last advance of Reuss Glacier are dated using a luminescence methodology. An age of 25 ka for sediment directly overlying the lodgement till corresponds with existing age constraints for the last maximal position of glaciers. Luminescence dating further implies an earlier advance of Reuss Glacier into the lowlands during Marine Isotope Stage 4. The data are discussed regarding potential changes in the source of precipitation during the Late Pleistocene.

Short summary
This paper is about deglaciation history in two areas of southern Norway. By dating rock surfaces we can estimate a minimum ice sheet thickness of 1476 m a.s.l. and a timing of deglaciation around 13 000 years ago in the western study area. In the eastern study area the deglaciation history is complex as the bedrock age most likely has inheritance from earlier ice-free periods. Comparing both study areas demonstrates the complex dynamics of the deglaciation in different areas in southern Norway.
