4D quantification of alpine permafrost degradation in steep rock walls using a laboratory‐calibrated electrical resistivity tomography approach
(
- Near Surface Geophysics
, 2021-03-09)
The warming of rock permafrost affects mechanical stability and hydro‐cryostatic pressures in rock walls. The coincident decrease in slope stability frequently affects infrastructure by creep and subsidence and promotes ...
Experimental Investigation of Apollo 16 “Rusty Rock” Alteration by a Lunar Fumarolic Gas
(
- Journal of Geophysical Research: Planets
, 2021-02-18)
The Apollo 16 sample 66095, named “Rusty Rock”, is enriched in volatile and moderately volatile elements. The impact melt breccia is characterized by abundant Fe‐rich sulfide and chloride alteration phases, including FeS, ...
Long-Term Wetting and Drying Trends in Land Water Storage Derived From GRACE and CMIP5 Models
(
- Journal of Geophysical Research: Atmospheres
, 2019)
Coupled climate models participating in the CMIP5 (Coupled Model Intercomparison Project Phase 5) exhibit a large intermodel spread in the representation of long-term trends in soil moisture and snow in response to ...
Studying the Global Spatial Randomness of Impact Craters on Mercury, Venus, and the Moon With Geodesic Neighborhood Relationships
(
- Journal of Geophysical Research: Planets
, 2021-03-29)
Impact crater records on planetary surfaces are often analyzed for their spatial randomness. Generalized approaches such as the mean second closest neighbor distance (M2CND) and standard deviation of adjacent area (SDAA) ...
Seafloor seepage in the Black Sea
(Univ. Bremen, 2007)
Black Sea, seafloor seepage, mud volcanoes, seeps, fluid migration, gas hydrates, diapirs. - The Black Sea is the worldwide largest anoxic basin with thick gas rich sediments facilitating seafloor seepage, which is widely ...
Stand-Alone Eastern Pacific Coastal Warming Events
(
- Geophysical Research Letters
, 2019)
A pronounced warm anomaly occurred at the Peruvian coast in early 2017. This “Coastal Niño” caused heavy rainfalls, leading to flooding in Peru and Ecuador. At the same time, neutral conditions prevailed in the equatorial ...
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 ...
Bacterial Stern layer diffusion: experimental determination with spectral induced polarization and sensitivity to nitrite toxicity
(
- Near Surface Geophysics
, 2019-08-07)
Spectral induced polarization signatures have been used as proxies for microbial abundance in subsurface environments, by taking advantage of the charged properties of microbial cell membranes. The method's applicability, ...
Stable Existence of Tropical Endorheic Lakes on Titan
(
- Geophysical Research Letters
, 2020)
Cassini detected numerous hydrocarbon seas/lakes in the polar region of Titan and wide areas of sand seas in the tropical region, which initially led to the perception that Titan's tropical region may be too dry for lakes. ...
Seismological and Geophysical Signatures of the Deep Crustal Magma Systems of the Cenozoic Volcanic Fields Beneath the Eifel, Germany
(
- Geochemistry, Geophysics, Geosystems
, 2020)
The Quaternary volcanic fields of the Eifel (Rhineland-Palatinate, Germany) had their last eruptions less than 13,000 years ago. Recently, deep low-frequency (DLF) earthquakes were detected beneath one of the volcanic ...
