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 de variations minéralogiques par surfaces de tendance dans les tephra du volcan El Chichón (Chiapas, Mexique)
(E&G – Quaternary Science Journal; Vol.35, No. 1)Im Verbreitungsgebiet der vom Vulkan El Chichón im Zeitraum März bis April 1982 geförderten Eruptiva wurden 74 Ascheproben entnommen. Die Leicht- und Schwermineralführung der entnommenen Proben wurde quantitativ bestimmt. ... -
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 ... -
Analyse und Konzeption von Messstrategien zur Erfassung der bodenhydraulischen Variabilität
(Univ. Dresden, 2007)Die Berücksichtigung der flächenhaften bodenhydraulischen Variabilität gilt bei der Modellierung von Wasser- und Stofftransportprozessen als problematisch. Dies liegt vorrangig an ihrer Erfassung, die kosten- und zeitintensiv ... -
Analyse von Bathymetrie und akustischer Rückstreuung verschiedener Fächersonar- und Sedimentecholot-Systeme zur Charakterisierung und Klassifizierung des Meeresbodens am Gakkel-Rücken, Arktischer Ozean
(Univ. Bremen, 2008)Im ersten Kapitel erfolgt nach der Zielsetzung und Motivation für die vorliegende Dissertation eine kurze geographische Beschreibung des Arktischen Ozeans und dessen tektonischer Entwicklung.Das Augenmerk gilt dabei dem ... -
Analyse von Butylzinnverbindungen in Sedimenten mittels GC-AED
(Univ. Hamburg, 2007)Organotin compounds are variously used industrial chemicals. One of the most toxicological relevant compounds is tributyltin (TBT). TBT has been used as an effective component in antifouling paints for decades. Thus, it ... -
Analyse von Telemetriesignalen und Radar-Rückstreusignalen zur Rekonstruktion von Bahnstörungen interplanetarer Raumsonden am Beispiel der simulierten Abstiegsdynamik der Huygens-Sonde
(Univ. Bochum, 2004)Die Cassini/Huygens-Mission ist ein gemeinsames Unternehmen von NASA und ESA, mit dem Ziel, das Saturnsystem zu erkunden. Die vorliegende Arbeit ist im Rahmen des Doppler-Wind-Experiments durchgeführt worden. Das Ziel der ... -
Analysis of Compound Climate Extremes and Exposed Population in Africa Under Two Different Emission Scenarios
; ; Rechid, D.; Pfeifer, S.; Raffaele, F.; ; ; Jacob, D. (Earth's Future, 2020)
It is well established that Africa is particularly exposed to climate extremes including heat waves, droughts, and intense rainfall events. How exposed Africa is to the co-occurrence of these events is however virtually ... -
Analysis of deformation and tectonic history of the Southern Altiplano Plateau (Bolivia) and their importance for plateau formation
(GFZ, Helmholtz-Zentrum, 2004)
The Altiplano represents a key region of the Central Andes, where the interplay between faults and syn-tectonic sediments allow the reconstruction of the kinematic evolution of the Central Andean high plateau. This study ... -
Analysis of future changes in meteorological drought patterns in Fulda, Germany
; Ivanov, Martin; ; Luterbacher, Jürg; (International Journal of Climatology, 2020)
Meteorological droughts have large impacts on society and the environment. A better understanding and quantification of their occurrences can be highly relevant for the development of proper climate change mitigation, ... -
Analysis of the development and structural drivers of raw‐material use in Germany
; Walz, Rainer (Journal of Industrial Ecology, 2020-11-27)
In orderto reduce the negative consequences of raw‐material extraction, it is necessary to accurately report raw‐material use and to understand its drivers in society. In this study, we conduct a multi‐regional environmentally ... -
Analysis of the Thermodynamic Phase Transition of Tracked Convective Clouds Based on Geostationary Satellite Observations
; ; (Journal of Geophysical Research: Atmospheres, 2020)
Clouds are liquid at temperature greater than 0°C and ice at temperature below −38°C. Between these two thresholds, the temperature of the cloud thermodynamic phase transition from liquid to ice is difficult to predict and ... -
Analytical Artefacts Preclude Reliable Isotope Ratio Measurement of Internal Water in Coral Skeletons
; ; ; ; ; ; ; ; ; (Geostandards and Geoanalytical Research, 2022-07-12)
Internal water in cold‐water and tropical coral skeletons was extracted and measured for its oxygen and hydrogen isotope ratios. Water was extracted by crushing pieces of coral hard tissue in a percussion device connected ... -
Analytical Solutions for Gravity Changes Caused by Triaxial Volumetric Sources
; (Geophysical Research Letters, 2022-04-18)
Volcanic crises are often associated with magmatic intrusions or the pressurization of magma chambers of various shapes. These volumetric sources deform the country rocks, changing their density, and cause surface uplift. ... -
Analyzing Internal Variability and Forced Response of Subdaily and Daily Extreme Precipitation Over Europe
; Ludwig, R. (Geophysical Research Letters, 2020)
At regional to local scales internal variability is expected to be a dominant source of uncertainty in analyzing precipitation extremes and mean precipitation even far into the 21st century. A debated topic is whether a ... -
Analyzing the impact of automatization using parallel daily mean temperature series including breakpoint detection and homogenization
