The seabed plays a key role in the marine carbon cycle as a) the terminal location of aerobic
oxidation of organic matter, b) the greatest anaerobic bioreactor, and c) the greatest …

The hadal zone, mostly comprising of deep trenches and constituting of the deepest part of
the world's oceans, represents the least explored habitat but one of the last frontiers on our …

The balance between photosynthetic organic carbon production and respiration controls
atmospheric composition and climate,. The majority of organic carbon is respired back to …

Hadal trenches are the deepest and most remote regions of the ocean. The 11-kilometer
deep Challenger Deep is the least explored due to the technical challenges of sampling …

Burial of persistent organic pollutants (POPs) such as polychlorinated biphenyls (PCBs) in
deep-sea sediments contributes to 60% of their historical emissions. Yet, empirical data on …

Hadal trench bottom (> 6000 m below sea level) sediments harbor higher microbial cell
abundance compared with adjacent abyssal plain sediments. This is supported by the …

The deepest part of the global ocean, hadal trenches, are considered to act as depocenters
for organic material. Relatively high microbial activity has been demonstrated in the deepest …

Organic anthropogenic pollutants reach even the deepest parts of the oceans, ie, the hadal
trenches. We here presented the concentrations, influencing factors, and potential sources …

Infrequent extreme events such as large earthquakes pose hazards and have lasting
impacts on landscapes and biogeochemical cycles. Sediments provide valuable records of …

Dating methodologies for Quaternary marine sediments play increasingly important roles in
the reconstruction of paleoenvironments and paleoclimate in (paleo) oceanography …
