We exemplify unimodal regional wind systems facilitating sand transport toward Tillandsiales. Tillandsiales show a low-energy wind system allowing sand accumulation of predominant grain sizes available at each site. Thereby Tillandsia landbeckii modifies and maintains its own microenvironment. Genomic data reveal high clonality and excess of heterozygosity promoting fitness in a hyperarid environment, and abiotic factors drive the selection of diverse and adaptive Tillandsia phenotypes.

We investigated geomorphological activity and stability of surfaces and soils along a climatic transect in the Atacama Desert. Single grain luminescence data and sediment analyses reveal recent deposition and shallow post-depositional mixing. Two distinct phases of enhanced activity align with previously reported wetter intervals, demonstrating the sensitivity of arid landscape dynamics to climatic variability.

We present the first chronology for offshore tsunami evidence from the Shetland Islands (United Kingdom) based on luminescence dating, addressing critical methodological challenges. Our results confirm sedimentary evidence of both the Storegga tsunami and a late-Holocene tsunami event. Our study demonstrates both the potential of luminescence dating for offshore tsunami deposits and the benefits of the associated chronologies for tsunami hazard assessment for the North Sea region.

The marshy, silted-up channel of the Late Glacial Bergstraßenneckar near Mannheim provided a rare source of clay in the sand- and gravel-dominated environment of the Rhine river. Based on satellite images, sedimentological, geophysical, and historical data, as well as optical dating, we identify a plot of sand-filled trenches where clay was mined around 1865 CE, which was only possible after groundwater lowering resulting from large-scale river regulation starting in the early 19th century.

Coastal boulder deposits record extreme wave events, both storm and tsunami. Fully understanding hazards as recorded in these deposits requires high-quality data for comparison among sites and over time. We analysed methodologies and constructed a comprehensive set of field measurements to improve data consistency and reproducibility. We aim to help geomorphologists produce of data that can be widely shared and used to build extensive analytic understanding of coastal boulder deposits.

Accurate elevation data is essential for flood risk assessment. We assess land elevation to local mean sea level of the Ayeyarwady Delta with a new, local DEM based on geodetic data and evaluate the performance of 10 global DEMs in an SLR impact assessment. Our study reveals major differences in performance between global DEMs and consequentially introduced uncertainty in SLR impact assessments, indicating potential similar uncertainties for other data-poor coastal lowlands around the world.

We reconstructed a wetland environment for a late Middle to Upper Pleniglacial (approx. 30–20 ka) loess sequence in western Germany. Typically, these sequences reveal terrestrial conditions with soil formation processes during this time frame. The here-investigated section, however, was influenced by periodical flooding, leading to marshy conditions and a stressed ecosystem. Our results show that the landscape of the study area was much more fragmented during this time than previously thought.

The late-glacial Bergstraßenneckar is a former course of the Neckar River in the Upper Rhine Graben of southwest Germany at a time when the confluence with the Rhine river was 50 km further to the north. The former river bends are still visible in topographic maps and satellite imagery. Sediment cores and geophysical measurements from the former river channels let us reconstruct the shift from a running river to silting-up meanders and permit us to date this to ca. 11 000 to 10 500 years ago.

Levinson-Lessing Lake in northern central Siberia provides an exceptional opportunity to study the evolution of the Earth's magnetic field in the Arctic. This is the first study carried out at the lake that focus on the palaeomagnetic record. It presents the relative palaeointensity and palaeosecular variation of the upper 38 m of sediment core Co1401, spanning ~62 kyr. A comparable high-resolution record of this time does not exist in the Eurasian Arctic.
Short summary
Block and boulder fields record catastrophic coastal flooding events and play a pivotal role in coastal hazard assessment. After Supertyphoon Haiyan on 8 Nov 2013 the transport of extremely large blocks of up to 180 t in E Samar (Philippines) was documented, indicating that hydrodynamic conditions induced by tropical cyclones, including infragravity waves, and resulting coarse-clast transport patterns may be comparable to tsunamis.
