Amplification of the Atlantic Multidecadal Oscillation associated with the onset of the industrial-era warming
(Scientific Reports, 2017) -
An Adaptive Hybrid Vertical Equilibrium/Full‐Dimensional Model for Compositional Multiphase Flow
(Water Resources Research, 2022-01-21)Efficient compositional models are required to simulate underground gas storage in porous formations where, for example, gas quality (such as purity) and loss of gas due to dissolution are of interest. We first extend the ... -
An analysis of the evolution of reactive species in Fe0/H2O systems.
(Journal of hazardous materials, 2009-09-15)Aqueous contaminant removal in the presence of metallic iron (e.g. in Fe(0)/H(2)O systems) is characterized by the large diversity of removing agents. This paper analyses the synergistic effect of adsorption, co-precipitation ... -
An andesitic sill complex in the Southern Permian Basin: volcanogenetic model and stratigraphic implications
(International Journal of Earth Sciences, 2020-07-28)Subvolcanic intrusions are highly variable in shape and structure, and occur in nearly all parts of the upper crust, as a result of extensive volcanic activity. Processes of subvolcanics interacting with the host rock are ... -
An automated testing device for continuous measurement of the hysteretic water retention curve of granular media
(Acta Geotechnica, 2020-02-11)The water retention curve (WRC), representing an important key for the modelling of hydro-mechanical behaviour of unsaturated soils, is still not fully understood, because it originates from microscopic hydraulic and ... -
An exceptional sedimentary record of initial rifting on the East African Plateau in the Miocene: Lessons from depositional cyclicity and palaeoenvironmental proxies
(The Depositional Record, 2022-11-20)Knowledge about the initial tectonic and depositional dynamics, as well as the influence of early rifting on climate and environmental evolution remains speculative to a large extent, because sediments are usually deeply ... -
An Exhumation Pulse From the Nascent Franciscan Subduction Zone (California, USA)
(Tectonics, 2020)We investigated a suite of metabasite blocks from serpentinite matrix and shale matrix mélanges of the California Coast Ranges. Our new data set consists of 40Ar/39Ar dates of amphibole and phengite and U-Pb dates of ... -
An Extension Strain Type Mohr–Coulomb Criterion
(Rock Mechanics and Rock Engineering, 2021-08-20)Extension fractures are typical for the deformation under low or no confining pressure. They can be explained by a phenomenological extension strain failure criterion. In the past, a simple empirical criterion for fracture ... -
An optimised whole mount in situ hybridisation protocol for the mollusc Lymnaea stagnalis
(BMC Developmental Biology, 2015)Abstract Background The ability to visualise the expression of individual genes in situ is an invaluable tool for developmental and evolutionary biologists; it allows for the characterisation of gene function, gene regulation ... -
An ~130 kyr Record of Surface Water Temperature and δ18O From the Northern Bay of Bengal: Investigating the Linkage Between Heinrich Events and Weak Monsoon Intervals in Asia
(Paleoceanography and Paleoclimatology, 2020)Millennial-scale reductions in monsoon precipitation, so-called Weak Monsoon Intervals (WMIs), have been identified in numerous paleoclimate records across the Afro-Asian monsoon domain throughout the last glacial-interglacial ... -
Analog Models of Lithospheric‐Scale Rifting Monitored in an X‐Ray CT Scanner
(Tectonics, 2023-03-01)Rifting and continental break‐up are fundamental tectonic processes, the understanding of which is of prime importance. However, the vast temporal and spatial scales involved pose major limitations to researchers. Analog ... -
Analogue experiments of salt flow and pillow growth due to basement faulting and differential loading
(Solid Earth, 2015)Salt flow in sedimentary basins is mainly driven by differential loading and can be described by the concept of hydraulic head. A hydraulic head in the salt layer can be imposed by vertically displacing the salt layer ... -
Analyse des Depots des Nitratumsatzes und dessen Heterogenität im quartären Grundwasserleiter des Wasserwerks Thülsfelde/Emsland Berücksichtigung bei der Modellierung des Transportes
(Univ. Dresden, 2006)Im Einzugsgebiet der Fassung A des Wasserwerks Thülsfelde wurden in langjährigen Beobachtungen Nitratgehalte an einzelnen Lokationen von bis zu 300 mg/L im oberflächennahen Grundwasser gemessen. Dennoch ist die betrachtete ... -
Ancient Origin of the Modern Deep-Sea Fauna
(PLoS ONE, 2012-10-10)The origin and possible antiquity of the spectacularly diverse modern deep-sea fauna has been debated since the beginning of deep-sea research in the mid-nineteenth century. Recent hypotheses, based on biogeographic patterns ... -
Anmerkungen zum Einfluss von dichtebeeinflussten Grundwasserströmungen im Bereich von Altlasten
(2008)Seit Beginn der systematischen Untersuchung von Altlasten ist an vielen Standorten, insbesondere Altablagerungen, der Einfluss von dichtebeeinflussten Grundwasserströmungen für die Ausbreitung von Schadstoffen festgestellt ... -
Anmerkungen zur Auswertung von Pumpversuchen mit artesischen Brunnen
(2010)Die Auswertung von Pumpversuchen mit konstantem Wasserspiegel, insbesondere Auslaufversuche an artesischen Brunnen, ist kein Standardverfahren in der Hydrogeologie. Da in Europa in Folge zurück gehender Grundwassernutzung ... -
Anmerkungen zur Berücksichtigung von Belastungen der Bodenluft im Baurechtsverfahren
(altlasten spektrum, 2019)Die zunehmende Bebauung mit Wohnhäusern auf ehemalig gewerblich genutzten Grundstücken sowie auf Grundstücken im Einflussbereich von Grundwasserkontaminationen macht es erforderlich, im Rahmen der behördlichen Bearbeitung ... -
Anmerkungen zur Schätzung von Schadstofffrachten im Grundwasser - Beobachtungen am Gartenzaun
(Altlasten Spektrum, 2020)Die Bundes-Bodenschutz- und Altlastenverordnung (BBodSchV) sieht in der Prüfung der Verhältnismäßigkeit von Maßnahmen neben Konzentrationen auch Frachten als Entscheidungskriterium vor. Die Schätzung von Frachten im ... -
Antarctic ice sheet expansions in the Middle Miocene and Pliocene
(Univ. Bremen, 2008)This study focuses on the interactions between climate and ice sheets in order to obtain a better understanding of the processes involved. Two periods in the geological past are explored; the Middle Miocene and the ... -
Anti‐Phased Miocene Ice Volume and CO2 Changes by Transient Antarctic Ice Sheet Variability
(Paleoceanography and Paleoclimatology, 2020-11-24)Geological evidence indicates large continental‐scale Antarctic ice volume variations during the early and mid‐Miocene. On million‐year timescales, these variations can largely be explained by equilibrium Antarctic ice ...
