Das System der Erde - was bewegt die Welt? Lebensraum und Zukunftsperspektiven
; Weber, Klaus (Hrsg.); Karg, Ute (Hrsg.) (Universitätsverlag Göttingen, 2005)
Our planet earth is a system - scarcely understood - of geological, biological und cosmic processes of great variety, which make it an interesting object of research. The papers listed here deal with topics of a series of ... -
Dating the Northwest Shelf of Australia Since the Pliocene
Groeneveld, J.;; ; (Geochemistry, Geophysics, Geosystems, 2021-03-08)
Accurate dating of marine sediments is essential to reconstruct past changes in oceanography and climate. Benthic foraminiferal oxygen isotope series from such sediments record long‐term changes in global ice volume and ... -
Deciphering fluid inclusions in high-grade rocks
(Geoscience Frontiers, 2014)The study of fluid inclusions in high-grade rocks is especially challenging as the host minerals have been normally subjected to deformation, recrystallization and fluid-rock interaction so that primary inclusions, formed ... -
Decompression and Fracturing Caused by Magmatically Induced Thermal Stresses
; ; ; (Journal of Geophysical Research: Solid Earth, 2023-03-17)
Studies of host rock deformation around magmatic intrusions usually focus on the development of stresses directly related to the intrusion process. This is done either by considering an inflating region that represents the ... -
Deep Geothermal Energy for Lower Saxony (North Germany) – Combined Investigations of Geothermal Reservoir Characteristics
(Energy Procedia, 2014)For the economic success of a geothermal project the hydraulic properties and temperature of the geothermal reservoir are crucial. New methodologies in seismics, geoelectrics and reservoir geology are tested within the ... -
Deep Heat: Proxies, Miocene Ice, and an End in Sight for Paleoclimate Paradoxes?
(Paleoceanography and Paleoclimatology, 2021-03-16)
The mid Miocene represents an important target for paleoclimatic study because the atmospheric CO2 concentration ranged from near modern values to ∼800 ppm, while a large, dynamic Antarctic ice sheet was likely to have ... -
Defining Hydrogeological Site Similarity with Hierarchical Agglomerative Clustering
; ; ;; (Groundwater, 2022-10-08)
Abstract Hydrogeological information about an aquifer is difficult and costly to obtain, yet ...

Deformation microstructures - Antarctic Ice from EPICA Dronning Maud Land and artificial creep test Ice
(Univ. Bremen, 2007)Ice, microstructures, subgrain boundaries, recrystallization, flow, deformation. - The primary objective of this thesis is the investigation of microstructures obtained from samples from the EPICA Dronning Maud Land ice ... -
Deformation von Fassadenplatten aus Marmor - Schadenskartierungen und gesteinstechnische Untersuchungen zur Verwitterungsdynamik von Marmorfassaden
(Universitätsverlag Göttingen, 2006-09)For about four decades marble has been used as thin veneer cladding. The durability of such thin slabs (mostly 30-40 mm) is satisfactory at most constructions. However, on numerous buildings all over the world, the ... -
Deglacial to Holocene variability in surface water characteristics and major floods in the Beaufort Sea
; ; ; ; ; ; ; (Communications Earth & Environment, 2020-10-09)
Surface water characteristics of the Beaufort Sea have global climate implications during the last deglaciation and the Holocene, as (1) sea ice is a critical component of the climate system and (2) Laurentide Ice Sheet ... -
Degradation of Root Community Traits as Indicator for Transformation of Tropical Lowland Rain Forests into Oil Palm and Rubber Plantations.
Sahner, Josephine; Budi, Sri Wilarso; Barus, Henry; Edy, Nur; Meyer, Marike;; Polle, Andrea (PloS one, 2015)
Conversion of tropical forests into intensely managed plantations is a threat to ecosystem functions. On Sumatra, Indonesia, oil palm (Elaeis guineensis) plantations are rapidly expanding, displacing rain forests and ... -
Denudation Rate Changes Along a Fast‐Eroding Mountainous River With Slate Headwaters in Taiwan From 10Be (Meteoric)/9Be Ratios
; ; ; (Journal of Geophysical Research: Earth Surface, 2020-02-18)
The novel 10Be (meteoric)/9Be system, where 10Be is delivered by precipitation and stable 9Be is released by weathering, provides denudation rates over weathering‐erosion timescales. The new tool is applicable to quartz‐poor ... -
Deposition of biogenic iron minerals in a methane oxidizing microbial mat.
Wrede, Christoph; Kokoschka, Sebastian; Dreier, Anne; Heller, Christina;; Hoppert, Michael (Archaea (Vancouver, B.C.), 2013)
The syntrophic community between anaerobic methanotrophic archaea and sulfate reducing bacteria forms thick, black layers within multi-layered microbial mats in chimney-like carbonate concretions of methane seeps located ... -
Depositional setting and limiting factors of early Late Cretaceous glaucony formation: implications from Cenomanian glauconitic strata (Elbtal Group, Germany)
(Facies, 2021-06-14)Cenomanian strata of the Elbtal Group (Saxony, eastern Germany) reflect a major global sea-level rise and contain, in certain intervals, a green authigenic clay mineral in abundance. Based on the integrated study of five ... -

Der Findling an der Eugen-Geinitz-Sicht in Usadel
(Neubrandenburger Geologische Beiträge; Vol.12)Bei dem für die Eugen-Geinitz-Sicht in Usadel ausgewählten Findling (Fundort: vermutlich Kiesgrube Siedenbüssow) handelt es sich um ein seltenes monomiktes Konglomerat, dessen Herkunft – und damit auch sein Bildungsalter ... -
Der Mittlere Muschelkalk in Bohrungen Norddeutschlands: Fazies, Geochemie, Zyklo- und Sequenzstratigraphie
(Univ. Halle, 2002)Im Rahmen dieser Arbeit wurde die evaporitische Schichtenfolge des Mittleren Muschelkalks im Norddeutschen Becken untersucht. Erstmals gelang es den Mittleren Muschelkalk sowohl am Kern lithostratigraphisch als auch in den ... -
Der Neubrandenburger Maler Manfred Asmuss und das geologische Naturerbe
(Neubrandenburger Geologische Beiträge, 2012-04-17)Die besondere Naturraumausstattung Mecklenburgs wird seit Jahrhunderten bis in die Gegenwart von zahlreichen Malern in Bildern dargestellt. Zu ihnen gehört auch Manfred Asmuss, Mitglied des Geowissenschaftlichen Vereins ... -
Deriving Debris‐Flow Dynamics From Real‐Time Impact‐Force Measurements
; ; ; ; (Journal of Geophysical Research: Earth Surface, 2023-03-21)
Understanding the impact forces exerted by debris flows is limited by a lack of direct field measurements and validated numerical models. In this study, we use real‐time impact‐force measurements and field observations of ... -
Description of an aerodynamic levitation apparatus with applications in Earth sciences
; Kremer, Katrina; Albrecht, Nina; Simon, Klaus; Kronz, Andreas (Geochemical Transactions, 2010)
Background: In aerodynamic levitation, solids and liquids are floated in a vertical gas stream. In combination with CO2-laser heating, containerless melting at high temperature of oxides and silicates is possible. We ...
