Relative quantification of wind erosion in argan woodlands in the Souss Basin, Morocco
(Earth Surface Processes and Landforms, 2020)The endemic argan woodlands cover large parts of South Morocco and create a characteristic landscape with areas of sparsely vegetated and bare soil surfaces between single trees. This unique ecosystem has been under extensive ... -
Release characteristics of overpressurised gas from complex vents: implications for volcanic hazards
(Bulletin of Volcanology, 2020-10-02)Many explosive volcanic eruptions produce underexpanded starting gas-particle jets. The dynamics of the accompanying pyroclast ejection can be affected by several parameters, including magma texture, gas overpressure, ... -
Relevant Reducing Agents in Remediation Fe0/H2O systems
(CLEAN - Soil, Air, Water, 2013) -
Relict high-Andean ecosystems challenge our concepts of naturalness and human impact
(Scientific Reports, 2017)What would current ecosystems be like without the impact of mankind? This question, which is critical for ecosystem management, has long remained unanswered due to a lack of present-day data from truly undisturbed ecosystems. ... -
Repeatedly Evolved Host-Specific Ectosymbioses between Sulfur-Oxidizing Bacteria and Amphipods Living in a Cave Ecosystem
(PLoS ONE, 2012-11-29)Ectosymbioses between invertebrates and sulfur-oxidizing bacteria are widespread in sulfidic marine environments and have evolved independently in several invertebrate phyla. The first example from a freshwater habitat, ... -
Representation of water abstraction from a karst conduit with numerical discrete-continuum models
(Hydrology and Earth System Sciences, 2014)Karst aquifers are characterized by highly conductive conduit flow paths embedded in a less conductive fissured and fractured matrix, resulting in strong permeability contrasts with structured heterogeneity and ... -
Rescuing Fe0 remediation research from its systemic flaws
(Research and Review Insights, 2017)The well-accepted assumption of metallic iron (Fe0) acting as electron donor for environmental remediation has created an unstable domain of knowledge for the past 23 years. This assumption is discouraging some outstanding ... -
Retrieval of Coarse-Resolution Leaf Area Index over the Republic of Kazakhstan Using NOAA AVHRR Satellite Data and Ground Measurements
(Remote Sensing, 2012)A new multi-decade national-wide coarse-resolution data set of leaf area index (LAI) over the Republic of Kazakhstan has been developed based on data from the Advanced Very High Resolution Radiometer (AVHRR) and in situ ... -
Retrospective evaluation of landslide susceptibility maps and review of validation practice
(Environmental Earth Sciences, 2021-07-21)Despite the widespread application of landslide susceptibility analyses, there is hardly any information about whether or not the occurrence of recent landslide events was correctly predicted by the relevant susceptibility ... -
Rettung für das Markttor von Milet: Schadensanalysen an Marmor, Mörtel und Stahl
(Georgia Augusta, 2005) -
Reuniting the Ötztal Nappe: the tectonic evolution of the Schneeberg Complex
(International Journal of Earth Sciences, 2021-11-27)The Ötztal Nappe in the Eastern Alps is a thrust sheet of Variscan metamorphic basement rocks and their Mesozoic sediment cover. It has been argued that the main part of the Ötztal Nappe and its southeastern part, the Texel ... -
Revealing Sediment Transport Pathways and Geomorphic Change in Washover Fans by Combining Drone‐Derived Digital Elevation Models and Single Grain Luminescence Data
(Journal of Geophysical Research: Earth Surface, 2021-01-23)Chronostratigraphic investigations on coastal sedimentary records such as washover fans or beach‐ridge sequences may be used to reconstruct storm chronologies on centennial to millennial time scales. However, modern analogs ... -
Review : The fundamental mechanism of aqueous contaminant removal by metallic iron

Review of Tertiary Gambier Limestone aquifer properties, lower South-East, South Australia
(Department of Water, Land and Biodiversity Conservation, Adelaide, SA2002)Transmissivity and storage coefficients are important properties in the characterisation of aquifers. Transmissivities and storage coefficients have been calculated from aquifer test programs for all known wells from the ... -
Revisiting afro-alpine Lake Garba Guracha in the Bale Mountains of Ethiopia: rationale, chronology, geochemistry, and paleoenvironmental implications
(Journal of Paleolimnology, 2020-06-30)Previous paleolimnological studies demonstrated that the sediments of Garba Guracha, situated at 3950 m asl in the afro-alpine zone of the Bale Mountains of Ethiopia, provide a complete Late Glacial and Holocene paleoclimate ... -
Revisiting the Middle Eocene Climatic Optimum “Carbon Cycle Conundrum” With New Estimates of Atmospheric pCO2 From Boron Isotopes
(Paleoceanography and Paleoclimatology, 2020)The Middle Eocene Climatic Optimum (MECO) was a gradual warming event and carbon cycle perturbation that occurred between 40.5 and 40.1 Ma. A number of characteristics, including greater-than-expected deep-sea carbonate ... -
Rheological change and degassing during a trachytic Vulcanian eruption at Kilian Volcano, Chaîne des Puys, France
(Bulletin of Volcanology, 2020-11-20)Magma ascent during silicic dome-forming eruptions is characterized by significant changes in magma viscosity, permeability, and gas overpressure in the conduit. These changes depend on a set of parameters such as ascent ...
