Muon paleotopometry Open
Recent advances in measuring muon fluxes at great depths for neutrino experiments, along with improvements in in-situ terrestrial cosmogenic nuclide (TCN) measurements, have enhanced our understanding of muogenic nuclide production rates a…

Virtual field sites at the UNESCO Geopark Serra da Estrela (Portugal) Open
Virtual field sites are increasing in popularity beyond classrooms. Also, field investigations greatly benefit from DGPS-referenced 3D models. We show a selection of field sites at the UNESCO Geopark Serra da Estrela (Portugal) and how the…

Conceptual proof, current application, and lab procedures to quantify crustal thickness variations with muon paleotopometry Open
Measuring the topographic relief evolution over hundreds of thousands to million-year timescales remains challenging. Current approaches use a mix of basin stratigraphy, numerical modelling of terrestrial cosmogenic nuclide (TCN) exposure …

Muon Paleotopometry – Measuring crustal thickness variations with muons? Open
Understanding topographic relief evolution and its changes over hundreds of thousands to million-year timescales remains challenging. Recent approaches usually combine numerical modelling of terrestrial cosmogenic nuclide (TCN) exposure ag…

Soil weathering dynamics and erosion in a dry oceanic area of the southern hemisphere (Otago, New Zealand) Open
Landscape evolution is driven by tectonics, climate and surface denudation. In New Zealand, tectonics and steep climatic gradients cause a dynamic landscape with intense chemical weathering, rapid soil formation, and high soil losses. In t…

Contrasting soil dynamics in the Serra da Estrela mountain plateau –  Portugal Open
<p>Limited data are available on how soil erosion rates compare between surfaces of different ages because short-term processes often overprint the longer-term erosion signal. This study investigated the soil dynamics among a formerl…

Identifying temporal and spatial denudation variations using in-situ terrestrial cosmogenic nuclides along vertical profiles on enrooted bedrock. Open
<p>Tors, thus large residual rocks that are still enrooted in bedrock, adorn landscapes around the world. In recent years it became apparent, that tors are useful dipsticks that hold records of surface lowering rates of their surroun…

Contrasting soil dynamics in a formerly glaciated and non-glaciated Mediterranean mountain plateau (Serra da Estrela, Portugal) Open
Few data are available on how soil erosion rates compare between surfaces of different ages because short-term processes often overprint the longer-term erosion signal. This study investigated the soil dynamics among two end-member sites, …

Soil characteristics and erosion in the UNESCO Geopark Estrela, Portugal. Open
<p>In Europe, a high soil erosion risk is modelled for the Mediterranean area such as the Iberian Peninsula (e.g., EEA, 2009), while actual field data often lacks behind. Here we present the first <sup>239+240</sup>Pu soi…

Surface denudation and soil erosion over 300 ka at the Otago upland (New Zealand) using 10Be and 239+240Pu Open
<p>The Tor Exhumation Approach (TEA) traditionally uses large residual granitic landforms as indicators for surface lowering over time of their surrounding landscape. This study challenged the broad applicability of this approach by …

Climate and relief‐induced controls on the temporal variability of denudation rates in a granitic upland Open
How soil erosion rates evolved over the last about 100 ka and how they relate to environmental and climate variability is largely unknown. This is due to a lack of suitable archives that help to trace this evolution. We determined in situ …

Comparison and Contrast in Soil Depth Evolution for Steady State and Stochastic Erosion Processes: Possible Implications for Landslide Prediction Open
The importance of gradual erosion relative to landsliding depends predominantly on the slope angle. One factor of critical influence in landsliding along with slope angle and slope shape is the soil depth. Understanding soil depth developm…

Prediction of Soil Formation as a Function of Age Using the Percolation Theory Approach Open
Recent modeling and comparison with field results showed that soil formation by chemical weathering, either from bedrock or unconsolidated material, is limited largely by solute transport. Chemical weathering rates are proportional to solu…

Landscapes and soils evolve in non‐linear ways over millennia. Current knowledge is incomplete as only average denudation (or erosion) rates are normally estimated, neglecting the temporal discontinuities of these processes. The determinat…
