Phylogenetic and physiological characterization of deep-biosphere microorganisms in El’gygytgyn Crater Lake sediments
… diverse and active microbial ecosystems in the deep subsurface – a biosphere that was originally considered devoid of life – was discovered in multiple microbiological studies. However, most of the studies are restricted to marine ecosystems, while our knowledge about the microbial communities …

Prevalence, persistence and consequences of microorganisms within oil field environments and mitigation strategies
The deep biosphere is home to an abundance of microorganisms. However, limitations to accessing deep subsurface samples means that very little is known about microorganisms from the marine and terrestrial subsurface. Oil and gas industry technologies, including advancements in hydraulic fracturing …

Characterization of microbial primary and secondary metabolism in the marine realm
… with a downcore reduction in subsurface biosphere diversity. Specific archaeal MAGs within the Thermoproteota and Hadarchaeota increased in abundance and recruitment of metatranscriptome reads towards deeper, hotter sediments, marking a transition to a specialized deep biosphere. In my …

Fracture Analysis of the Lower Oceanic Crust, Atlantis Bank, Southwest Indian Ridge
… the redistribution of nutrients supporting the deep biosphere. However, little has been done to understand the brittle history of OCCs especially in their footwall. AB is one of the best studied OCCs in the world, which makes it an ideal location for this study providing insight into the brittle …
