Ice Age geomorphological Ahorn Valley and Ailsbach River terrace evolution – and its importance for the cave use possibilities by cave bears, top predators (hyenas, wolves and lions) and humans (Neanderthals, Late Palaeolithics) in the Frankonian Karst
(E&G, 2013-12-20)The Sophie’s Cave in Upper Franconia, Bavaria (South Germany) eroded into Upper Jurassic reef dolomite and is a perfect model including all three stages of cave development ranging from a 1. ponor cave, to 2. intermediate ... -
Ice-Rafted Erratics and Bergmounds from Pleistocene Outburst Floods, Rattlesnake Mountain, Washington, USA
(E&G – Quaternary Science Journal, 2014-06-29)Exotic ice-rafted debris from the breakup of ice-dammed glacial lakes Missoula and Columbia is common in slackwater areas along the 1,100-km route for outburst floods in the northwestern US. A detailed analysis was performed ... -
Idealistic vision or reality? - life-long learning among the Romany ethnic groups

Ideas and perspectives: hydrothermally driven redistribution and sequestration of early Archaean biomass – the “hydrothermal pump hypothesis”
(Biogeosciences, 2018)Archaean hydrothermal chert veins commonly contain abundant organic carbon of uncertain origin (abiotic vs. biotic). In this study, we analysed kerogen contained in a hydrothermal chert vein from the ca. 3.5 Ga ... -
Identification of uppercrustal discontinuities using dip curvature analysis of isostatic residual gravity: examples from the central Andes
(11. Symposium "Tektonik, Struktur- und Kristallingeologie", 2006-03)Structural analysts are often faced with the problem of identifying prominent structural discontinuities covered by post-tectonic sedimentary or volcanic rocks. Gravity fields are often used to delineate the trace of buried ... -
Imaging of Cenozoic climatic events and bottom water activities at the northeastern flank of Walvis Ridge: A correlation of seismic data with borehole data measurements
(Univ. Bremen, 2008)Seismic, marine, walvis ridge, bottom currents, climatic events. - The history of sedimentation and current activities at the northeastern flank of Walvis Ridge is investigated by a correlation of multichannel seismic data ... -
Imaging of vertical seismic profiling data using the common-reflection-surface stack
(Univ. Karlsruhe, 2008)Diese Dissertation beschäftigt sich mit der Entwicklung eines automatisierten, datenorientierten Abbildungsverfahrens, das auf der sogenannten Common-Reflection-Surface (CRS) Stapelung basiert. Durch die Miteinbeziehung ... -
Imbalanced nutrients as triggers for black shale formation in a shallow shelf setting during the OAE 2 (Wunstorf, Germany)
(Biogeosciences, 2012-10-29)During the oceanic anoxic event 2 (OAE 2) in the Mid-Cretaceous Period, widespread black shale (BS) formation occurred, reflecting perturbations in major biogeochemical cycles. Here we present geochemical and biomarker ... -
Impact of Fe0 amendment on methylene blue discoloration by sand columns
(Chemical Engineering Journal, 2013)The influence of metallic iron (Fe0) amendment on the efficiency of sand to discolor a 2.0 mg L-1 methylene blue (MB) solution was investigated in column studies. MB was used as an indicator to identify the optimum Fe0/sand ... -
Impact of MnO2 on the efficiency of metallic iron for the removal of dissolved CrVI, CuII, MoVI, SbV, UVI and ZnII
(Chemical Engineering Journal, 2011)The idea that manganese oxide (MnO2) sustains the reactivity of metallic iron (Fe0) is investigated in this study. A multi-elemental aqueous system containing CrVI, CuII, MoVI, SbV, UVI, and ZnII (each about 100 μM) was ... -
The importance of lithological heterogeneity of the Onaping Formation for understanding post-impact deformation of the Sudbury Impact Structure, Canada
(11. Symposium "Tektonik, Struktur- und Kristallingeologie", 2006-03)The suevitic Onaping Formation overlies the layered Main Mass of the 1.85Ga Sudbury Igneous Complex (SIC) of the Sudbury Impact Structure, Ontario. The Formation consists of four Members, namely from top to bottom, the ... -
Improving the sustainability of granular iron/pumice systems for water treatment.
(Journal of environmental management, 2013-05-30)Metallic iron (Fe(0)) is currently used in subsurface and above-ground water filtration systems on a pragmatic basis. Recent theoretical studies have indicated that, to be sustainable, such systems should not contain more ... -
Impuls- und Wärmeaustausch zwischen der Atmosphäre und dem eisbedeckten Ozean
(Univ. Bremen, 2001)Turbulence, ice ridge, polynja, drag coefficient. - Polarstern (PS) cruise ARK XII led into the Laptev Sea and into the Kara Sea. Measurements of atmospheric processes within the polar surface layer were performed by a ... -
