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 ... -

Aqueous contaminant removal by metallic iron: Is the paradigm shifting?
(Water SA, 2011)Chemical reduction has long dominated the thinking about the mechanism of aqueous contaminant removal in the presence of metallic iron (e.g. Fe0/H2O systems). However, a large body of experimental evidence indicates that ... -
Archaea in past and present geobiochemical processes and elemental cycles.
(Archaea (Vancouver, B.C.), 2013)For a long time, Archaea have been considered as an ancient prokaryotic group comprising specialists restricted to narrow ecological niches. This opinion might have been supported by the characteristics of the first ... -
Arctic Sea Ice in CMIP6
(Geophysical Research Letters, 2020-05-14)We examine CMIP6 simulations of Arctic sea‐ice area and volume. We find that CMIP6 models produce a wide spread of mean Arctic sea‐ice area, capturing the observational estimate within the multimodel ensemble spread. The ... -
Arsenic Release from a Natural Rock under Near-natural Oxidizing Conditions
(Engineering in Life Sciences, 2008)The effects of carbonate concentration and the presence of iron hydroxide phases on the process of arsenic release from an ore material were investigated under experimental oxic conditions and in the pH range from 6.0 to ... -
Ascomycete fungi on dimension stone of the “Burg Gleichen”, Thuringia
(Environmental Earth Sciences, 2011)In the present study, the diversity of ascomycete fungi was investigated on two wall areas of the “Burg Gleichen”, Thuringia (Germany), made of various types of sandstones, travertine and Grenzdolomit. From a W-exposed, ... -
Aspects of pelagic sedimentation in the Devonian of Western Europe
(Reading : Geological Institute, 1971)During the Devonian of the Rhenich geosyncline (sediments exposed in the Rheinisches Schiefergebirge and Harz Mountains, Central Germany) condensed pelagic limestones, locally rich in cephalopods (Cephalopodenkalk), ... -
Assessing the utility of trace and rare earth elements as biosignatures in microbial iron oxyhydroxides
(Frontiers in Earth Science, 2015)Microbial iron oxyhydroxides are common deposits in natural waters, recent sediments, and mine drainage systems. Along with these minerals, trace and rare earth elements (TREE) are being accumulated within the mineralizing ... -
Assessment of the heterogeneity of hydraulic properties in gravelly outwash plains: a regionally scaled sedimentological analysis in the Munich gravel plain, Germany
(Hydrogeology Journal, 2020-08-11)The favorable overall conditions for the utilization of groundwater in fluvioglacial aquifers are impacted by significant heterogeneity in the hydraulic conductivity, which is related to small-scale facies changes. Knowledge ...
