Comparison of Denitrification Induced by Various Organic Substances—Reaction Rates, Microbiology, and Temperature Effect
; ; ; ; (Water Resources Research, 2021-11-18)
Widespread groundwater pollution with nitrate (NO3−) and the finite and decreasing geogenic NO3− degradation capacity in aquifers require a better understanding of potential treatment methods. This project aimed at exploring ... -
Compound Events in South America Using the CORDEX‐CORE Ensemble: Current Climate Conditions and Future Projections in a Global Warming Scenario
; ; ; (Journal of Geophysical Research: Atmospheres, 2022-11-06)
Climate hazards associated with compound events (CEs) have lately received increasing attention over South America (SA) due to their potential risks and amplification of impacts. This work addressed the evaluation of ... -
Electrification of Experimental Volcanic Jets with Varying Water Content and Temperature
; ; ; ; (Geophysical Research Letters, 2019)
Volcanic lightning—a near ubiquitous feature of explosive volcanic eruptions—possesses great potential for the analysis of volcanic plume dynamics. To date, the lack of quantitative knowledge on the relationships between ... -
Gehen wir auf eine neue Eiszeit zu?
(E&G – Quaternary Science Journal; Vol.38, No. 1)In der öffentlichen Diskussion der Gegenwart tauchen in fast regelmäßigem Abstand Meldungen, auch solche von manipulativem Charakter aus der Ecke der Regenbogenpresse auf, in welchen der Menschheit das baldige Erscheinen ... -
Middle Miocene Climate and Stable Oxygen Isotopes in Europe Based on Numerical Modeling
; ; ; ; ; ; ; ; ; ; (Paleoceanography and Paleoclimatology, 2022-10-24)
The Middle Miocene (15.99–11.65 Ma) of Europe witnessed major climatic, environmental, and vegetational change, yet we are lacking detailed reconstructions of Middle Miocene temperature and precipitation patterns over ... -
Near-Complete Local Reduction of Arctic Stratospheric Ozone by Severe Chemical Loss in Spring 2020
; ; Lehmann, R.; ; ; ; Davies, J.; ; Jepsen, N.; ; Lyall, N.; Rex, M. (Geophysical Research Letters, 2020)
In the Antarctic ozone hole, ozone mixing ratios have been decreasing to extremely low values of 0.01–0.1 ppm in nearly all spring seasons since the late 1980s, corresponding to 95–99% local chemical loss. In contrast, ... -
Paleotemperature Changes in the Upper and Middle Pleistocene
(E&G – Quaternary Science Journal; Vol.18, No. 1)Aus festländischen und marinen Daten wird gefolgert, daß die Glazialzeiten des mittleren und oberen Pleistozäns zeitlich von gleicher Größenordnung waren. Die Temperaturen der einzelnen Eiszeiten waren nicht genau gleich: ... -
Seasonal Differences in the Attenuation of Polar Trace Organics in the Hyporheic Zone of an Urban Stream
; ; ; ; (Water Resources Research, 2022-01-20)
Attenuation of trace organic compounds (TrOCs) in a river occurs to a large extent in its hyporheic zone. A major part of the attenuation of polar TrOCs is of microbial origin. As microbial activity depends on temperature ... -
Testing the consistency of Holocene and Last Glacial Maximum spatial correlations in temperature proxy records
; ; (Journal of Quaternary Science, 2020)
Holocene temperature proxy records are commonly used in quantitative synthesis and model-data comparisons. However, comparing correlations between time series from records collected in proximity to one another with the ...
