Evolution of (Bio‐)Geochemical Processes and Diagenetic Alteration of Sediments Along the Tectonic Migration of Ocean Floor in the Shikoku Basin off Japan
Köster, Male; Kars, Myriam
; Schubotz, Florence
; Tsang, Man‐Yin; Maisch, Markus
; Kappler, Andreas
; Morono, Yuki
; Inagaki, Fumio
; Heuer, Verena B.
; Kasten, Sabine
; Henkel, Susann
(Geochemistry, Geophysics, Geosystems, 2021-08-03)
Biogeochemical processes in subseafloor sediments are closely coupled to global element cycles. To improve the understanding of changes in biogeochemical conditions on geological timescales, we investigate sediment cores ... -
Fate of nitrate during groundwater recharge in a fractured karst aquifer in Southwest Germany
Visser, Anna-Neva; Lehmann, Moritz F.; Rügner, Hermann; D’Affonseca, Fernando Mazo; Grathwohl, Peter; Blackwell, Nia; Kappler, Andreas
; Osenbrück, Karsten
(Hydrogeology Journal, 2021-02-18)
Over the past decades, fractured and karst groundwater systems have been studied intensively due to their high vulnerability to nitrate (NO3−) contamination, yet nitrogen (N) turnover processes within ... -
Growth of microaerophilic Fe(II)‐oxidizing bacteria using Fe(II) produced by Fe(III) photoreduction
Lueder, Ulf; Maisch, Markus
; Jørgensen, Bo Barker; Druschel, Gregory; Schmidt, Caroline; Kappler, Andreas
(Geobiology, 2022-01-11)
Iron(II) (Fe(II)) can be formed by abiotic Fe(III) photoreduction, particularly when Fe(III) is organically complexed. Light‐influenced environments often overlap or even coincide with oxic or microoxic geochemical conditions, ... -
Microbial biosignatures in ancient deep‐sea hydrothermal sulfides
Deep‐sea hydrothermal systems provide ideal conditions for prebiotic reactions and ancient metabolic pathways and, therefore, might have played a pivotal role in the emergence of life. To understand this role better, it ... -
Redoxtrons – An experimental system to study redox processes within the capillary fringe
Dorau, Kristof; Uteau, Daniel
; Maisch, Markus
; Kappler, Andreas
; Peth, Stephan
; Mansfeldt, Tim
(European Journal of Soil Science, 2023-02-22)
Spatiotemporal characterisation of the soil redox status within the capillary fringe (CF) is a challenging task. Air‐filled porosities (ε), oxygen concentration (O2) and soil redox potential (EH) are interrelated ...
