Ecogenomics reveals viral communities across the Challenger Deep oceanic trench [PDF]
Analysis of 13 sediment cores from the Challenger Deep of Marian Trench (down to 11 kilometers depth) identified distinct operational taxonomic units and relevant auxiliary metabolic genes, providing further insight into deep-sea viral metabolic ...

Revealing the full biosphere structure and versatile metabolic functions in the deepest ocean sediment of the Challenger Deep [PDF]
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 on Earth, lag far behind that of other marine realms.

Microbiomes in the Challenger Deep slope and bottom-axis sediments [PDF]
The V-shaped Challenger Deep in the Mariana Trench is the deepest part of the world’s oceans. Using 586 prokaryotic metagenome-assembled genomes and metatranscriptomic data, this study explores metabolic capabilities and activities of microorganisms ...

Virioplankton assemblages from challenger deep, the deepest place in the oceans [PDF]
Summary: Hadal ocean biosphere, that is, the deepest part of the world’s oceans, harbors a unique microbial community, suggesting a potential uncovered co-occurring virioplankton assemblage.

Spatial variations of microbial communities in abyssal and hadal sediments across the Challenger Deep [PDF]
Microbial communities in hadal sediments are least explored in hadal zone (>6,000 m), especially in the Challenger Deep with high pressure (∼110 M pa at the bottom).

Seasonal variability of water characteristics in the Challenger Deep observed by four cruises [PDF]
Thirty conductivity-temperature-depth profiler casts in the Challenger Deep were conducted during four cruises from December 2015 to February 2017. Two cruises took place in the summer, and two in the winter.

Full-ocean-depth EM124 mapping of the Challenger Deep by R/V Hakuho-maru and depth-estimate sensitivity tests [PDF]
The Challenger Deep in the Mariana Trench is the deepest known point on Earth, yet recent depth estimates still differ by several meters because of environmental and instrumental uncertainties. Here we present a new full-ocean-depth multibeam bathymetric

Influence of Extremely High Pressure and Oxygen on Hydrocarbon-Enriched Microbial Communities in Sediments from the Challenger Deep, Mariana Trench [PDF]
Recent studies reported that highly abundant alkane content exists in the ~11,000 m sediment of the Mariana Trench, and a few key alkane-degrading bacteria were identified in the Mariana Trench.

The Impact of Post-Harvest Potato Storage on (Deep-Fried) Potato Mash Properties [PDF]
This study investigated whether storage changes the composition of Fontane and Challenger potatoes, including their starch characteristics, and whether these changes impact the properties of (deep-fried) mashes made from these potatoes stored for up to ...

Vertical distribution and metabolic diversity of autotrophic microbes in the deep sediment of the challenger deep [PDF]
Background Carbon fixation in marine ecosystems is a vital process that contributes to climate regulation, with ocean sediments playing a critical role in carbon sequestration. This process is driven by chemolithoautotrophy in marine sediments, fueled by
