The remineralization of organic carbon (OC) in marine sediments has crucial implications for
global carbon cycling and climate change. However, OC turnover rates differ significantly …

We address the role of the Congo River sediment dispersal in exporting and trapping
organic carbon into deep offshore sediments. Of particular interest is the Congo submarine …

The correlation between concentrations of dissolved barium (dBa) and silicon (dSi) in the
modern ocean supports the use of Ba as a paleoceanographic proxy. However, the …

The coastal waters off the Changjiang Estuary are a seasonal hypoxic region, offering an
ideal system for studying the geochemical cycles of redox sensitive elements (RSEs) at the …

Methane-rich fluids arising from organic matter diagenesis in deep sediment layers sustain
chemosynthesis-based ecosystems along continental margins. This type of cold seep …

The concentration of atmospheric carbon dioxide (CO 2) is a crucial climate parameter as it
has far-reaching implications on global temperature. The oceans are a significant sink for …

Miocene thin-bedded turbidites from Tierra del Fuego record scarce graphoglyptids and two
unusual ichnoguilds composed of diminutive elite trace fossils. The first, a …

The Congo deep-sea fan is directly connected to the Congo River by a unique submarine
canyon. The Congo River delivers up to 2× 10 12 gPOC/yr, a part of which is funnelled by …

Deep-sea fans are well known depot centers for organic carbon that should promote sulfate
reduction. At the same time, the high rates of deposition of unconsolidated metal oxides from …

The diagenetic processes of organic matter (OM) in hadal sedimentary environments (>
6000 m water depth) are much less studied than those in other accessible environments. In …
