(Journal of Applied Crystallography, 2020-12-02)Two evaluation concepts for nondestructive depth‐resolved X‐ray residual stress analysis in the near‐surface region of materials with cubic symmetry and nearly single crystalline structure are introduced by simulated ... -
Conch geometry, ontogeny and dimorphism in the Early Bajocian ammonoid Stephanoceras from Normandy, France
; (Lethaia, 2021-07-22)
A large suite of specimens belonging to the Early Bajocian Stephanoceras from Évrecy (Normandy, France) displays wide variation in conch and sculpture. The quantitative analysis of the conch geometry and its ontogeny on ... -
Concretionary methane-seep carbonates and associated microbial communities in Black Sea sediments
; Peckmann, J.; Blumenberg, M.; Michaelis, W.; Reimer, A.; (Palaeogeography, Palaeoclimatology, Palaeoecology, 2005)
Gas seeps in the euxinic northwestern Black Sea provide an excellent opportunity to study anaerobic, methane-based ecosystems with minimum interference from oxygen-dependent processes. An integrated approach using fluorescence- ... -
Cone penetration tests in dry and saturated Ticino sand
; ; ; ; ; (Bulletin of Engineering Geology and the Environment, 2021-03-11)
It is commonly assumed that dry and saturated sands exhibit similar cone resistance–relative density relationships. Some studies pointed out that partial saturation and calcareous sands with considerable fines content are ... -
Confinement and anisotropy of ultrahigh-energy cosmic rays in isotropic plasma wave turbulence
(Univ. Bochum, 2007)We have investigated the implications of isotropically distributed interstellar magnetohydrodynamic plasma waves on the scattering mean free path and the spatial anisotropy of high-energy cosmic rays. We demonstrate a ... -
Conjugation of artificial humic acids with inorganic soil matter to restore land for improved conservation of water and nutrients
; ; ; (Land Degradation & Development, 2019)
Artificial soil (AS) with a dark–brown appearance and high soil organic matter (SOM) was manufactured under hydrothermal conditions from poor sandy landfill using the 'hydrothermal humification process.' This approach may ... -
Consequences of land-use change and the wildfire disaster of 2017 for the central Chilean biodiversity hotspot
; ; ; (Regional Environmental Change, 2021-03-25)
Central Chile is an important biodiversity hotspot in Latin America. Biodiversity hotspots are characterised by a high number of endemic species cooccurring with a high level of anthropogenic pressure. In central Chile, ... -
Consequences of regularizing the Sawyer–Eliassen equation in balance models for tropical cyclone behaviour
; (Quarterly Journal of the Royal Meteorological Society, 2019)
The consequences of regularizing the Sawyer–Eliassen equation to calculate the stream function for the axisymmetric secondary circulation of a tropical cyclone are explored. Regularization is an ad hoc procedure in which ... -
Considering different recent advancements in GNSS on real-time zenith troposphere estimates
; ; (GPS Solutions, 2020-07-30)
Global navigation satellite system (GNSS) remote sensing of the troposphere, called GNSS meteorology, is already a well-established tool in post-processing applications. Real-time GNSS meteorology has been possible since ... -
Consistent Nighttime Atomic Oxygen Concentrations From O2 A-band, O(1S) Green-Line, and OH Airglow Measurements as Performed by SCIAMACHY
; (Geophysical Research Letters, 2019)
A new atomic oxygen data set was derived from nighttime SCanning Imaging Absorption spectroMeter for Atmospheric CHartographY (SCIAMACHY) O2 A-band measurements. It is compared to atomic oxygen obtained from SCIAMACHY O(1S) ... -
Consolidation of volcanic tuffs with TEOS and TMOS: a systematic study
; ; ; (Environmental Earth Sciences, 2021-12-08)
In this study, nine volcanic tuffs from Armenia, Germany and Mexico were treated with two commercially available consolidants on base of silicic acid ester, as well as different pretreatments with an anti-swelling agent ... -
Constraining Andean Propagation of Exhumation at the Limit of the Eastern Cordillera, NW Argentina, Using Low‐Temperature Thermochronology in a Structural Context
; ; ; ; (Tectonics, 2022-08-16)
Within the Central Andes of NW Argentina, the spatiotemporal distribution and style of deformation is strongly influenced by pre‐Cenozoic heterogeneities, mostly related to the Salta rift extension in the Cretaceous. At ... -
Constraining Europa's Subsolar Atmosphere With a Joint Analysis of HST Spectral Images and Galileo Magnetic Field Data
; (Journal of Geophysical Research: Space Physics, 2022-09-06)
We constrain Europa's tenuous atmosphere on the subsolar hemisphere by combining two sets of observations: oxygen emissions at 1,304 and 1,356 Å from Hubble Space Telescope (HST) spectral images and Galileo magnetic field ... -
Constraining Global Marine Iron Sources and Ligand‐Mediated Scavenging Fluxes With GEOTRACES Dissolved Iron Measurements in an Ocean Biogeochemical Model
; ; ; ; ; ; ; ; (Global Biogeochemical Cycles, 2021-08-09)
Iron is a key micronutrient controlling phytoplankton growth in vast regions of the global ocean. Despite its importance, uncertainties remain high regarding external iron source fluxes and internal cycling on a global ... -
Constraining Internal States in Progressive Rock Failure of Carrara Marble by Measuring Residual Strains With Neutron Diffraction
; ; ; (Journal of Geophysical Research: Solid Earth, 2020)
Knowledge of the internal state of rock is key to anticipate its rheological response and susceptibility to external factors. Time-dependent failure in rock is controlled by internal state changes, like damage accumulation ... -
