Global Health - A Challenge for Interdisciplinary Research
(Universitätsverlag GöttingenGöttingen, 2012)Human, animal and plant health is a field of work which offers opportunities for inter- and trans-disciplinary research. The whole topic bridges the natural and social sciences. Today, in a world of global environmental ... -
Grain size and mineralogical indicators of weathering in the Oberlaab loess-paleosol sequence, Upper Austria
(E&G – Quaternary Science Journal; Vol.62)Grain size analyses, bulk and clay mineralogical data were used to characterize weathering within the loess-paleosol-sequence of Oberlaab in Upper Austria. Soil horizons can be clearly identified by the calculation of ... -
Grain-Size Control on Petrographic Composition of Sediments: Compositional Regression and Rounded Zeros
(Mathematical GeosciencesMathematical Geosciences, 2009)It is well-known that sediment composition strongly depends on grain size. A number of studies have tried to quantify this relationship focusing on the sand fraction, but only very limited data exists covering wider grain ... -
Granitic dimensional stones in Uruguay: evaluation and assessment of potential resources
(Environmental Earth Sciences, 2012)In Uruguay commercial granite varieties comprise mafic rocks, granitoids, and syenitoids. There is a long tradition in Uruguay, as well as worldwide, of using dimensional stones in architecture and art, specially granitic ... -
Greenhouse gas emissions from soils—A review
Oertel, Cornelius;
; Zurba, Kamal; Zimmermann, Frank; Erasmi, Stefan (Chemie der Erde - Geochemistry, 2016)
Soils act as sources and sinks for greenhouse gases (GHG) such as carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O). Since both storage and emission capacities may be large, precise quantifications are needed ... -
Groundwater flow reversal between small water bodies and their adjoining aquifers: A numerical experiment
; ; ; (Hydrological Processes, 2023-05-24)
Abstract The countless kettle holes in the Late Pleistocene landscapes of Northern Europe are ...

(Neubrandenburger Geologische Beiträge, 2012-04-17)Die Herbstexkursion der Sammlergruppe führte 21 Mitglieder und Freunde des Geowissenschaftlichen Vereins Neubrandenburg vom 30. September bis 3. Oktober 2010 in die Geologie von Halle/Saale und Umgebung. Im Stadtgebiet ... -
Hans Peter Cornelius (1888–1950): a perfect mapping geologist and scientific explorer of the Alps
; (International Journal of Earth Sciences, 2020-07-06)
Hans Peter Cornelius was a squeamishly and accurately mapping field geologist with an eye for the finest detail as well as for the large-scale architectural structure of mountain ranges. His excellent work concerned the ... -
Harzgeologie 2016 - 5. Workshop Harzgeologie : Kurzfassungen und Exkursionsführer
Friedel, Carl-Heinz (Hrsg.); (Göttingen contributions to geosciences - GCG;Volume 78)
Dieser Band enthält Beiträge zur Geologie des Harzes und seines Umfeldes, die anlässlich des 5. Workshops Harzgeologie am Geowissenschaftlichen Zentrum der Georg-August-Universität Göttingen vorgestellt wurden. Der Band ... -
Heterogeneous vesiculation of 2011 El Hierro xeno-pumice revealed by X-ray computed microtomography
(Bulletin of Volcanology, 2016)During the first week of the 2011 El Hierro submarine eruption, abundant light-coloured pumiceous, high-silica volcanic bombs coated in dark basanite were found floating on the sea. The composition of the light-coloured ... -
High groundwater levels: Processes, consequences, and management
; ; ; (Wiley Interdisciplinary Reviews: Water, 2022-08-19)
In recent years, the issue of high groundwater levels has caught attention. Unfavorable consequences of high groundwater levels are especially damage to buildings, infrastructure, and the environment. Processes that lead ... -
High spatio‐temporal resolution measurements of cohesive sediment erosion
; Inskeep, Caleb; ; Schmid, Gerhard; ; (Earth Surface Processes and Landforms, 2020-06-14)
In this study, we present a novel approach to measure fundamental processes of cohesive sediment erosion. The experimental setup consists of a laboratory erosion flume (SETEG) and a photogrammetric method to detect sediment ... -
High-Resolution Imaging of Texture and Microstructure by the Moving Detector Method
(Textures and microstructures, 2003)In order to describe texture and microstructure of a polycrystalline material completely, crystal orientation g={?1F?2} must be known in all points x={x1?x2?x3} of the material. This can be achieved by locationresolved ... -
Higher subsoil carbon storage in species-rich than species-poor temperate forests
(Environmental Research Letters, 2014)Forest soils contribute ca. 70% to the global soil organic carbon (SOC) pool and thus are an important element of the global carbon cycle. Forests also harbour a large part of the global terrestrial biodiversity. It is ... -
Higher than present global mean sea level recorded by an Early Pliocene intertidal unit in Patagonia (Argentina)
; ; ; ; ; ; ; ; (Communications Earth & Environment, 2020-12-23)
Reconstructions of global mean sea level from earlier warm periods in Earth’s history can help constrain future projections of sea level rise. Here we report on the sedimentology and age of a geological unit in central ... -
Highly isotopically depleted isoprenoids ; molecular markers for ancient methane venting
; ; Seifert, Richard; Wehrung, Patrick; ; Michaelis, Walter (Geochimica et cosmochimica acta, 1999)
We propose that organic compounds found in a Miocene limestone from Marmorito (Northem Italy) are source markers for organic matter present in aneient methane vent systems (cold seeps). The limestone contains high ... -
Hillslope Sediment Supply Limits Alluvial Valley Width
; ; (AGU Advances, 2022-10-31)
River‐valley morphology preserves information on tectonic and climatic conditions that shape landscapes. Observations suggest that river discharge and valley‐wall lithology are the main controls on valley width. Yet, current ... -
