Idealistic vision or reality? - life-long learning among the Romany ethnic groups
(Discussion Papers / Centre for Regional Studies of Hungarian Academy of Science; 53) -
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 groundwater mean transit times of precipitation and riverbank infiltration by two-component lumped parameter models
(Hydrological Processes, 2019)Groundwater transit time is an essential hydrologic metric for groundwater resources management. However, especially in tropical environments, studies on the transit time distribution (TTD) of groundwater infiltration and ... -
Identification of suitable sites for managed aquifer recharge under semi-arid conditions employing a combination of numerical and analytical techniques
(Environmental Earth Sciences, 2021-08-14)Overpumping or overexploitation of groundwater is one of the major threats for aquifer systems in arid and semi-arid areas. Managed aquifer recharge (MAR) has been suggested by many researchers as a sustainable and effective ... -
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 ... -
Identifying decision-relevant uncertainties for dynamic adaptive forest management under climate change
(Climatic Change, 2020-11-09)The decision on how to manage a forest under climate change is subject to deep and dynamic uncertainties. The classic approach to analyze this decision adopts a predefined strategy, tests its robustness to uncertainties, ... -
Identifying Dominant Processes in Time and Space: Time‐Varying Spatial Sensitivity Analysis for a Grid‐Based Nitrate Model
(Water Resources Research, 2022-08-04)Distributed models have been increasingly applied at finer spatiotemporal resolution. However, most diagnostic analyses aggregate performance measures in space or time, which might bias subsequent inferences. Accordingly, ... -
Identifying Global‐Scale Patterns of Vegetation Change During the Last Deglaciation From Paleoclimate Networks
(Paleoceanography and Paleoclimatology, 2021-12-20)During the last deglaciation (∼19–11 ka before present), the global mean temperature increased by 3–8 K. The concurrent hydroclimate and land cover changes are not well constrained. Here, we use a pollen database to quantify ... -
Identifying Radiation Belt Electron Source and Loss Processes by Assimilating Spacecraft Data in a Three-Dimensional Diffusion Model
(Journal of Geophysical Research: Space Physics, 2020)Data assimilation aims to blend incomplete and inaccurate data with physics-based dynamical models. In the Earth's radiation belts, it is used to reconstruct electron phase space density, and it has become an increasingly ... -
An Image Segmentation Approach for the Detection of Small-scale Magnetic Anomalies
(2022)Due to the still enormous burden of unexploded ordnance (UXO) in the subsurface worldwide, the safe recovery of a wide variety of buried weapons and ammunition requires efficient and reliable detection methods. Using a ... -
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 Small‐Scale Heterogeneity and Absorption Using Adjoint Envelope Tomography: Results From Laboratory Experiments
(Journal of Geophysical Research: Solid Earth, 2022-11-11)To complement the information provided by deterministic seismic imaging at length scales above a certain resolution limit we present the first application of adjoint envelope tomography (AET) to experimental data. AET uses ... -
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 ... -
Imaging seismic wave-fields with AlpArray and neighboring European networks
(International Journal of Earth Sciences, 2021-11-25)The AlpArray experiment and the deployment of Swath-D together with the dense permanent network in Italy allow for detailed imaging of the spatio-temporal imaging complexity of seismic wave-fields within the greater Alpine ... -
Imaging the Absorbing Feeding and Eruptive Pathways of Deception Island, Antarctica
(Geophysical Research Letters, 2022-10-04)Deception Island is one of the most active and best‐documented volcanoes in Antarctica. Since its last eruption in 1970, several geophysical surveys have targeted reconstructing its magmatic systems. However, geophysics ... -
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 ... -
Immiscible silicate liquids: K and Fe distribution as a test for chemical equilibrium and insight into the kinetics of magma unmixing
(Contributions to Mineralogy and Petrology, 2021-05-24)Silicate liquid immiscibility leading to formation of mixtures of distinct iron-rich and silica-rich liquids is common in basaltic and andesitic magmas at advanced stages of magma evolution. Experimental modeling of the ... -
