TL;DR: Evidence is provided for the existence of microbial communities in ~40° to 60°C sediment associated with lignite coal beds at ~1.5 to 2.5 km below the seafloor in the Pacific Ocean off Japan, which suggests that terrigenous sediments retain indigenous community members tens of millions of years after burial in the seabed.

TL;DR: The depth of oxygen penetration and microbial activity in marine sediments varies by region as mentioned in this paper, and the depth of microbial communities varies with the region of interest, and the microbial communities can be found up to 75 meters below the sea floor.

TL;DR: Investigating microbial life in up to 1.2-kilometer-deep and up to 120°C hot sediments in the Nankai Trough subduction zone found that microbial life decreases as depth and temperature increases down to ∼600 meters below the seafloor, corresponding to temperatures of ∼70°C.
Journal ArticleDOI
Dust, volcanic ash, and the evolution of the South Pacific Gyre through the Cenozoic
Ann G Dunlea,Richard W. Murray,Justine Sauvage,Arthur J. Spivack,Robert N. Harris,Steven D'Hondt +5 more
TL;DR: In this article, the authors examined the 0-100 Ma paleoceanographic record retained in pelagic clay from the South Pacific Gyre (SPG) by analyzing 47 major, trace, and rare earth elements in bulk sediment in 206 samples from seven sites drilled during Integrated Ocean Drilling Program Expedition 329.
Journal ArticleDOI
Relationship of Bacterial Richness to Organic Degradation Rate and Sediment Age in Subseafloor Sediment
Emily Walsh,John B. Kirkpatrick,Robert A. Pockalny,Justine Sauvage,Arthur J. Spivack,Richard W. Murray,Mitchell L. Sogin,Steven D'Hondt +7 more
TL;DR: It is shown that bacterial richness in subseafloor sediment declines exponentially with sediment age, and in parallel with organic-fueled oxidation rate, which suggests that subseAFloor diversity ultimately depends on electron donor diversity and/or total community respiration.
