Reconstructions of past changes in dissolved oxygen concentrations in the abyssal ocean
are of interest to paleoceanographers because of their potential to help characterize and …

The natural carbon cycle is immensely intricate to fully understand its sources, fluxes and the
processes that are responsible for their cycling in different reservoirs and their balances on a …

Enhanced ocean carbon storage during the Pleistocene ice ages lowered atmospheric CO2
concentrations by 80 to 100 ppm relative to interglacial levels. Leading hypotheses to …

We studied sediments from the ca. 1400 million-year-old Xiamaling Formation from the
North China block. The upper unit of this formation (unit 1) deposited mostly below storm …

At present, the Arabian Sea has a permanent oxygen minimum zone (OMZ) at water depths
between about 100 and 1200 m. Active denitrification in the upper part of the OMZ is …

The ecology of aerobic microorganisms is never explored in marine oxygen minimum zone
(OMZ) sediments. Here we reveal aerobic bacterial communities along∼ 3 m sediment …

Biogeochemistry of oxygen minimum zone (OMZ) sediments, which are characterized by
high input of labile organic matter, have crucial bearings on the benthic biota, gas and metal …

Rose-Bengal-stained foraminiferal assemblages (> 150 μm) were analysed along a five-
station bathymetric transect across the core and the lower part of the oxygen minimum zone …

Abstract The Indian Monsoon and the westerlies strongly influence the sedimentation in the
northeastern Arabian Sea by impacting rainfall and erosion on land and on biogeochemical …

Abstract The Arabian Sea represents a prime example of an open ocean extended oxygen
minimum zone (OMZ) with low oxygen concentrations (down to less than 2 µM) between 200 …
