Carbon and sulfur isotopic data, together with biomarker and iron speciation analyses of the
Hovea-3 core that was drilled in the Perth Basin, Western Australia, indicate that euxinic …

We investigated the rates of the main microbiological processes (primary production, aerobic
and anaerobic carbon degradation) and transport phenomena in an intertidal sand plate …

This paper is the outcome of a community initiative to identify major unsolved scientific
problems in hydrology motivated by a need for stronger harmonisation of research efforts. The …

The main terminal processes of organic matter mineralization in anoxic Black Sea
sediments underlying the sulfidic water column are sulfate reduction in the upper 2–4 m and …

Sixteen short sediment cores were recovered from the upper edge (UEO), within (WO) and
below (BO) the oxygen minimum zone (OMZ) off Peru during cruise 147 of R/V Sonne. Solids …

Coexisting dissolved sulfide and sulfate from hypersulfidic interstitial waters of a 380- m-long
sediment core show a large isotopic difference of up to 72‰ caused by in situ microbial …

Molybdenum (Mo) isotope fractionation has recently been introduced as a new proxy in
oceanography and biogeochemistry. It is therefore fundamental to understand the processes …

Bacterial disproportionation of elemental sulfur is an important process in the sulfur cycle of
natural sediments and leads to the formation of hydrogen sulfide and sulfate. The oxygen …

Pelagic redoxclines of anoxic basins and deeps form the suboxic transition between oxygenated
surface and anoxic or even sulfidic bottom waters. Intense element cycling, favoured by …

Aims: Ethyl glucuronide (EtG) and ethyl sulfate (EtS) are conjugated ethanol metabolites
formed in low amounts after alcohol consumption. Compared with ethanol, EtG and EtS are …
