Investigating the Release of Co-precipitated Uranium from Iron Oxides
; Schöner, A.; Dienemann, H.; (Journal of Radioanalytical and Nuclear Chemistry, 2006)
The removal of uranium (VI) in zerovalent iron permeable reactive barriers and wetlands can be explained by its association with iron oxides. The long term stability of this immobilized U is yet to be addressed. The ... -

Investigation of subsurface connectivity and subsurface stormflow in low mountain ranges—Findings from the two research catchments Obere Brachtpe and Bohlmicke (Germany)
; (Hydrological Processes, 2022-02-12)
The two small research catchments Obere Brachtpe (2.6 km2; 50.989986, 7.752013) and Bohlmicke (1 km2, 51.079319, 7.892988) are located in the Rhenish Massif, a low mountain range in Germany. Land use in both catchments is ... -
Investigation of the dwarf galaxy population in Hickson compact groups
(Univ. Bochum, 2003)The nature of compact galaxy groups, which is important concerning the influence of the environment on member galaxies, is largely unknown. In this work dwarf galaxies are investigated in the outer regions of compact galaxy ... -
Investigation of the properties of iron-bearing alloys and silicates and their implications for the Earth's lower mantle and core
(Univ. Bayreuth, 2009)(1) (Mg,Fe)(Si,Al)O3 perovskite comprises about 80% of the Earth's lower mantle by volume, leaving ~ 15% to (Mg,Fe)O ferropericlase and ~ 5% to CaSiO3 perovskite. Therefore characteristics of the lower mantle would be ... -
Investigation of the temporal variability of thunderstorms in central and western Europe and the relation to large-scale flow and teleconnection patterns
;; ; (Quarterly Journal of the Royal Meteorological Society, 2019)
The driving factors that influence the spatial and annual variability of thunderstorms across Europe are still poorly understood. Due to a lack of long-term, reliable and consistent information about the occurrence of ... -
Investigation of UV Absorbers on Venus Using the 283 and 365 nm Phase Curves Obtained From Akatsuki
; ; ; Yamada, M.; ; Encrenaz, T. (Geophysical Research Letters, 2021-04-08)
The so‐called unknown absorber in the clouds of Venus is an important absorber of solar energy, but its vertical distribution remains poorly quantified. We analyze the 283 and 365 nm phase curves of the disk‐integrated ... -
Investigations into the opening of fractures during hydraulic testing using a hybrid-dimensional flow formulation
; ; (Environmental Earth Sciences, 2021-07-30)
We applied a hybrid-dimensional flow model to pressure transients recorded during pumping experiments conducted at the Reiche Zeche underground research laboratory to study the opening behavior of fractures due to fluid ... -
Investment traps and resilience to shocks: An experimental study of Central Asian collective water governance
; ; (Irrigation and Drainage, 2022-03-16)
We theoretically and empirically investigate the investments of water users in a stylized local irrigation system. We model irrigation self‐management as an interdependent interaction of users in an evolutionary game and ... -
Ionospheric Corrections for Satellite Altimetry ‐ Impact on Global Mean Sea Level Trends
; (Earth and Space Science, 2022-04-25)
Atmospheric delay corrections for satellite altimetry measurements are essential for deriving highly accurate sea surface heights and reliable global mean sea level (GMSL) trend estimates. A commonly used method to correct ... -
Ionospheric Signatures of Secondary Waves From Quasi‐6‐Day Wave and Tide Interactions
; (Journal of Geophysical Research: Space Physics, 2021-03-31)
A sudden stratospheric waring occurred in the southern hemisphere during September 2019, accompanied by an exceptionally strong quasi‐6‐day wave (Q6DW). We examine the ionospheric response using global total electron content ... -

Iron Exports From Catchments Are Constrained by Redox Status and Topography
; ; ; ; ; ; (Global Biogeochemical Cycles, 2022-01-18)
Fe(III) hydroxides stabilize organic carbon (OC) and P in soils. Observations of rising stream Fe concentrations are controversially posited to result from a flushing of iron‐rich deeper soil layers or a decrease of competing ... -
Iron isotope fractionation in soil and graminaceous crops after 100 years of liming in the long‐term agricultural experimental site at Berlin‐Dahlem, Germany
; ; Berns, Anne E.; Schweitzer, Kathlin; ; Bol, Roland; Amelung, Wulf (European Journal of Soil Science, 2020-03-04)
Sustainable arable cropping relies on repeated liming. Yet, the associated increase in soil pH can reduce the availability of iron (Fe) to plants. We hypothesized that repeated liming, but not pedogenic processes such as ... -

Is Coulomb Stress the Best Choice for Aftershock Forecasting?
; ; ; (Journal of Geophysical Research: Solid Earth, 2020)
The Coulomb failure stress (CFS) criterion is the most commonly used method for predicting spatial distributions of aftershocks following large earthquakes. However, large uncertainties are always associated with the ... -
Is the soil moisture precipitation feedback enhanced by heterogeneity and dry soils? A comparative study
