Hypoxia causes preservation of labile organic matter and changes seafloor microbial community composition (Black Sea)
Bottom-water oxygen supply is a key factor governing the biogeochemistry and community
composition of marine sediments. Whether it also determines carbon burial rates remains …

Faunal responses to oxygen gradients on the Pakistan margin: a comparison of foraminiferans, macrofauna and megafauna
The Pakistan Margin is characterised by a strong mid-water oxygen minimum zone (OMZ)
that intercepts the seabed at bathyal depths (150–1300m). We investigated whether faunal …

Sedimentary phosphorus and iron cycling in and below the oxygen minimum zone of the northern Arabian Sea
In this study, we investigate phosphorus (P) and iron (Fe) cycling in sediments along a depth
transect from within to well below the oxygen minimum zone (OMZ) in the northern Arabian …

Vertical distribution and respiration rates of benthic foraminifera: Contribution to aerobic remineralization in intertidal mudflats covered by Zostera noltei meadows
The present study investigates the influence of seagrass root systems on benthic hard-
shelled meiofauna (foraminifera). In February and July 2011, sediment cores were collected …

Burial and decomposition of plant pigments in surface sediments of the Baltic Sea: role of oxygen and benthic fauna
Degradation and burial of organic matter in sediments are important processes for oxygen
dynamics and thus for the outcome of eutrophication. To assess the influences of bottom …
