Coupling of diagenetic alterations and mechanical properties of Lower Permian siliciclastic sandstones: a pilot study
; ; ; ; ; (Environmental Earth Sciences, 2021-02-07)
Initial detrital composition and authigenic alterations during diagenesis of three sandstone types are related to their mechanical properties. Sandstones were prepared for geotechnical standard tests [density, uniaxial ... -
Coupling of the Subpolar Gyre and the Overturning Circulation During Abrupt Glacial Climate Transitions
; Mikolajewicz, U.; Kleppin, H.; (Geophysical Research Letters, 2020-11-05)
We present a mechanism for self‐sustained ocean circulation changes that cause abrupt temperature changes over Greenland in a multimillennial climate model simulation with glacial CO2 concentrations representative of Marine ... -

Throughout spring and summer 2020, ozone stations in the northern extratropics recorded unusually low ozone in the free troposphere. From April to August, and from 1 to 8 kilometers altitude, ozone was on average 7% ... -
Cr isotopes in physically separated components of the Allende CV3 and Murchison CM2 chondrites: Implications for isotopic heterogeneity in the solar nebula and parent body processes
; Becker, Harry; Harbott, Andreas (Meteoritics & Planetary Science, 2019-08-12)
Chromium isotopic data of physically separated components (chondrules, CAIs, variably magnetic size fractions) of the carbonaceous chondrites Allende and Murchison and bulk rock data of Allende, Ivuna, and Orgueil are ... -
Created by the Monte Peron rock avalanche: Lago di Vedana (Dolomites, Italy) and its sediment record of landscape evolution after a mass wasting event
; ; (Landslides, 2021-11-27)
The timing of the Monte Peron Landslide is revised to 2890 cal. BP based on a radiocarbon-dated sediment stratigraphy of Lago di Vedana. This age fosters the importance of hydroclimatic triggers in the light of accelerating ... -
Cretaceous Evolution of the Central Asian Proto-Paratethys Sea: Tectonic, Eustatic, and Climatic Controls
; ; ; ; ; ; ; ; ; ; ; (Tectonics, 2020)
The timing and mechanisms of the Cretaceous sea incursions into Central Asia are still poorly constrained. We provide a new chronostratigraphic framework based on biostratigraphy and magnetostratigraphy together with ... -
Critical infrastructure cascading effects. Disaster resilience assessment for floods affecting city of Cologne and Rhein-Erft-Kreis
(Journal of Flood Risk Management, 2020)
At the case study of the city of Cologne and the neighbouring Rhein-Erft-Kreis (a county), selected resilience aspects of critical infrastructure (CI) and cascading effects are analysed concerning major river floods. Using ... -
Critical Soil Moisture Derived From Satellite Observations Over Europe
; ; ; (Journal of Geophysical Research: Atmospheres, 2020)
Evapotranspiration (ET) is a crucial quantity through which land surface conditions can impact near-surface weather and vice versa. ET can be limited by energy or water availability. The transition between water- and ... -

Critical Zone Response Times and Water Age Relationships Under Variable Catchment Wetness States: Insights Using a Tracer‐Aided Ecohydrological Model
; ; ; (Water Resources Research, 2022-04-26)
The dynamic relationships between water flux and storage, together with the associated water ages and speed of hydrological responses (as proxies for velocity and celerity respectively) are fundamental to understanding how ... -
Critical Zone Storage Controls on the Water Ages of Ecohydrological Outputs
; ; ; (Geophysical Research Letters, 2020-08-13)
Spatially explicit knowledge of the origins of water resources for ecosystems and rivers is challenging when using tracer data alone. We use simulations from a spatially distributed model calibrated by extensive ecohydrological ... -
Crop diversity effects on temporal agricultural production stability across European regions
; ; ; ; (Regional Environmental Change, 2021-10-05)
Stabilizing agricultural production is fundamental to food security. At the national level, increasing the effective diversity of cultivated crops has been found to increase temporal production stability, i.e., the ... -
CRS-stack-based seismic reflection imaging for land data in time and depth domains
(Univ. Karlsruhe, 2007)Land data acquisition often suffers from rough top-surface topography and complicated near-surface conditions. The resulting poor data quality makes conventional data processing very difficult. Under such circumstances, ... -
Crustal architecture of a metallogenic belt and ophiolite belt: implications for mineral genesis and emplacement from 3-D electrical resistivity models (Bayankhongor area, Mongolia)
; ; ; (Earth, Planets and Space, 2021-04-01)
Crustal architecture strongly influences the development and emplacement of mineral zones. In this study, we image the crustal structure beneath a metallogenic belt and its surroundings in the Bayankhongor area of central ... -

Crustal Porosity of Lunar Impact Basins
; ; Wünnemann, K.; Oberst, J. (Journal of Geophysical Research: Planets, 2020-04-18)
Lateral variations in bulk density and porosity of the upper lunar highland crust are mapped using a high‐resolution Gravity Recovery and Interior Laboratory (GRAIL) gravity field model and Lunar Reconnaissance Orbiter (LRO) ... -
Crustal structure modelling and interpretation of the East Greenland continental margin between 72°N and 77°N
