TL;DR: In this article, the authors compare analyses of sediments underlying two regions of the eastern North Pacific Ocean, one which has oxygen-depleted bottom waters and one with typical oxygen distributions.

TL;DR: In this paper, the authors report a test of the hypothesis that the extent of organic matter preservation in continental margin sediments is controlled by the average period accumulating particles reside in oxic porewater immediately beneath the water/sediment interface.

TL;DR: A comprehensive overview of the current understanding of potential exoplanet biosignatures, including gaseous, surface, and temporal signatures, can be found in this article, with a focus on recent advances in assessing biosignature plausibility.

TL;DR: A comprehensive, cultivation-independent census of microbial communities in 37 samples collected from these geothermal fields, encompassing sites ranging in temperature from 55.1 to 93.6°C, in pH from 2.5 to 9.4, and in mineralogy from silicates in Rehai to carbonates in Ruidian significantly expands the current understanding of the microbiology in Tengchong hot springs.

TL;DR: The role of oxygen in the preservation of organic matter on a margin with a strong oxygen-deficient zone and on a typical western continental margin was investigated in this paper. But, the results were limited to the continental margins of northwest Mexico and Washington State.
