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 – Quaternary Science Journal; Vol.62)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 Age‐Holocene Similarity of Foraminifera‐Bound Nitrogen Isotope Ratios in the Eastern Equatorial Pacific
; ; ; ; ; ; ; (Paleoceanography and Paleoclimatology, 2021-05-19)
Bulk sediment δ15N records from the eastern tropical Pacific (ETP) extending back to the last ice age most often show low glacial δ15N, then a deglacial δ15N maximum, followed by a gradual decline to a late Holocene δ15N ... -
Ice Aggregation in Low‐Level Mixed‐Phase Clouds at a High Arctic Site: Enhanced by Dendritic Growth and Absent Close to the Melting Level
; ; (Journal of Geophysical Research: Atmospheres, 2022-08-19)
Low‐level mixed‐phase clouds (MPCs) occur extensively in the Arctic, and are known to play a key role for the energy budget. While their characteristic structure is nowadays well understood, the significance of different ... -
The Ice Data Hub as a powerful interface between data and simulations
; ; ; (2023)
Providing measurements for scientific simulation software often requires tedious manual preprocessing of data sets. To overcome this problem and make it easy for simulation tools to access heterogeneous data sets directly, ... -
Ice Particle Properties Inferred From Aggregation Modelling
; ; ; ; ; (Journal of Advances in Modeling Earth Systems, 2020)
We generated a large number 105,000 of aggregates composed of various monomer types and sizes using an aggregation model. Combined with hydrodynamic theory, we derived ice particle properties such as mass, projected area, ... -
Ice-Rafted Erratics and Bergmounds from Pleistocene Outburst Floods, Rattlesnake Mountain, Washington, USA
(E&G – Quaternary Science Journal; Vol.63)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 ... -
ICON‐O: The Ocean Component of the ICON Earth System Model—Global Simulation Characteristics and Local Telescoping Capability
; ; ; ; ; ; ; ; ; ; ; ; ; ; (Journal of Advances in Modeling Earth Systems, 2022-10-06)
We describe the ocean general circulation model Icosahedral Nonhydrostatic Weather and Climate Model (ICON‐O) of the Max Planck Institute for Meteorology, which forms the ocean‐sea ice component of the Earth system model ... -
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”
; ; Bauersachs, Thorsten; Mißbach, Helge; Reinhardt, Manuel; Schäfer, Nadine; Van Kranendonk, Martin J.; (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 uppercrustal discontinuities using dip curvature analysis of isostatic residual gravity: examples from the central Andes
; Götze, Hans-Joachim; ; ; Hongn, Fernado; Petrinovic, Ivan (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 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 vertical seismic profiling data using the common-reflection-surface stack
