Abstract Background The Mariana Trench is the deepest known site in the Earth's oceans,
reaching a depth of~ 11,000 m at the Challenger Deep. Recent studies reveal that hadal …

Relatively few studies have described the microbial populations present in ultra-deep hadal
environments, largely as a result of difficulties associated with sampling. Here we report …

The low temperature and elevated hydrostatic pressure in hadal trenches at water depths
below 6000 m render sample collection difficult. Here, in situ hadal water microbial samples …

Hadal trenches, oceanic locations deeper than 6,000 m, are thought to have distinct
microbial communities compared to those at shallower depths due to high hydrostatic …

Hadal oceans at water depths below 6,000 m are the least-explored aquatic biosphere. The
Challenger Deep, located in the western equatorial Pacific, with a water depth of∼ 11 km, is …

Marine hydrocarbon-degrading bacteria play an important role in natural petroleum
biodegradation processes and were initially associated with man-made oil spills or natural …

Background The full biosphere structure and functional exploration of the microbial
communities of the Challenger Deep of the Mariana Trench, the deepest known hadal zone …

Abstract Background Hadal trenches (> 6000 m) are the deepest oceanic regions on Earth
and depocenters for organic materials. However, how these enigmatic microbial ecosystems …

Hadal biosphere represents the deepest part of the ocean with water depth> 6,000 m.
Accumulating evidence suggests the existence of unique microbial communities dominated …

Hadal ocean sediments, found at sites deeper than 6,000 m water depth, are thought to
contain microbial communities distinct from those at shallower depths due to high …
