Imbalanced nutrients as triggers for black shale formation in a shallow shelf setting during the OAE 2 (Wunstorf, Germany)
(Biogeosciences, 2012-10-29)During the oceanic anoxic event 2 (OAE 2) in the Mid-Cretaceous Period, widespread black shale (BS) formation occurred, reflecting perturbations in major biogeochemical cycles. Here we present geochemical and biomarker ... -
Immiscible silicate liquids: K and Fe distribution as a test for chemical equilibrium and insight into the kinetics of magma unmixing
;
(Contributions to Mineralogy and Petrology, 2021-05-24)
Silicate liquid immiscibility leading to formation of mixtures of distinct iron-rich and silica-rich liquids is common in basaltic and andesitic magmas at advanced stages of magma evolution. Experimental modeling of the ... -
Impact Experiment on Gneiss: The Effects of Foliation on Cratering Process
Agarwal, Amar; Poelchau, Michael H.;; Rae, Auriol; Ebert, Matthias (Journal of Geophysical Research: Solid Earth, 2019)

Impact of an 0.2 km3 Rock Avalanche on Lake Eibsee (Bavarian Alps, Germany) – Part I: Reconstruction of the paleolake and Effects of the Impact
; Mamot, Philipp; Lempe, Bernhard; (Earth Surface Processes and Landforms, 2020-11-16)
Rock avalanches destroy and reshape landscapes in only a few minutes and are among the most hazardous processes on Earth. The surface morphology of rock avalanche deposits and the interaction with the underlying material ... -
Impact of an 0.2 km3 Rock Avalanche on Lake Eibsee (Bavarian Alps, Germany) – Part II: Catchment Response to Consecutive Debris Avalanche and Debris Flow
; ; Lempe, Bernhard; (Earth Surface Processes and Landforms, 2020-11-16)
The ~0.2 km3 Eibsee rock avalanche impacted Paleolake Eibsee and completely displaced its waters. This study analyses the lake impact and the consequences, and the catchment response to the landslide. A quasi‐3D seismic ... -
Impact of biochar on nutrient supply, crop yield and microbial respiration on sandy soils of northern Germany
; Priyadarshani, S.H. Renuka; Haefele, Stephan M.; Schröder, Nicola; Pfeiffer, Eva‐Maria (European Journal of Soil Science, 2021-02-08)
The application of biochar to agricultural soils to increase nutrient availability, crop production and carbon sequestration has gained increasing interest but data from field experiments on temperate, marginal soils are ... -
Impact of climate variability of the Western Tropical Pacific on maximum salinity water in the South China Sea
;; (Ocean Dynamics, 2021-08-31)
Salinity observations in the Vietnamese upwelling area in June 2016 indicated a significant increase in the salinity of the maximum salinity water (MSW). The source of MSW inflow into the South China Sea (SCS) is a mixture ... -
Impact of Cyclonic Wind Anomalies Caused by Massive Winter Sea Ice Retreat in the Barents Sea on Atlantic Water Transport Toward the Arctic: A Model Study
; ; ; ; (Journal of Geophysical Research: Oceans, 2023-03-15)
The Arctic is warming much faster than the global average. This is known as Arctic Amplification and is caused by feedbacks in the local climate system. In this study, we explore a previously proposed hypothesis that an ... -
Impact of different chloride salts and their concentrations on nitrification and trace gas emissions from a sandy soil under a controlled environment
Guo, Yafei; Becker‐Fazekas, Stefan; (Soil Use and Management, 2021-03-10)
Potassium chloride (KCl) and magnesium chloride (MgCl2) can be used to reduce carbon dioxide (CO2) and nitrous oxide (N2O) emissions, but their efficacy can be strongly affected by their Cl− concentration. This study aimed ... -

Impact of Eurasian Ice Sheet and North Atlantic Climate Dynamics on Black Sea Temperature Variability During the Penultimate Glacial (MIS 6, 130–184 ka BP)
; ; ; (Paleoceanography and Paleoclimatology, 2020)
Understanding hemisphere-wide millennial-scale temperature variability during past glacials in response to ice sheet dynamics and orbital forcing is one of the key targets for Quaternary climate research. While an inland ... -
Impact of Fe0 amendment on methylene blue discoloration by sand columns
Miyajima, K.; (Chemical Engineering Journal, 2013)
The influence of metallic iron (Fe0) amendment on the efficiency of sand to discolor a 2.0 mg L-1 methylene blue (MB) solution was investigated in column studies. MB was used as an indicator to identify the optimum Fe0/sand ... -
Impact of flex power on GPS Block IIF differential code biases
