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: In this paper, a method for simultaneous analysis of microbial identity and function is described. But the method is based on the visualization of oligonucleotide probe-conferred hybridization signal in single microbial cells and isotopic measurement using high-resolution ion microprobe (NanoSIMS).

TL;DR: Cold seeps, located along the Sonora Margin transform fault in the Guaymas Basin, were extensively explored during the ‘BIG’ cruise in June 2010 and molecular results indicate that metabolically active archaeal communities were dominated by known clades of anaerobic methane oxidizers, including a novel ‘ANME-2c Sonora’ lineage.

TL;DR: In this paper, an expedition of the RV Urania was devoted to exploration of the genomic richness of deep hypersaline anoxic lakes (DHALs) located in the Western part of the Mediterranean Ridge Approximately 40 nautical miles SE from Urania Lake, the presence of anoxic hypersaline lake was confirmed by swath bathymetry profiling and through immediate sampling casts.

TL;DR: Results, which combine enrichment culturing with DGGE analysis, indicated that enrichment cultures derived from inoculum dilution and media with various concentrations of carbon could facilitate the detection and isolation of a greater number of environmentally relevant bacterial species than when using traditional enrichment techniques alone.
