High frequency of phylogenetically diverse reductive dehalogenase-homologous genes in deep subseafloor sedimentary metagenomes

Frontiers in Microbiology, 2014
Marine subsurface sediments on the Pacific margin harbor diverse microbial communities even at depths of several hundreds meters below the seafloor (mbsf) or more.

Using Cathodic Poised Potential Experiments to Investigate Extracellular Electron Transport in the Crustal Deep Biosphere of North Pond, Mid-Atlantic Ridge

Frontiers in Environmental Science, 2020
The crustal sub-seafloor covers a large portion of the Earth’s surface but is poorly understood as a habitat for life. It is unclear what metabolisms support the microscopic cells that have been observed, and how they survive under resource limitation ...

Ancient and Modern Geochemical Signatures in the 13,500-Year Sedimentary Record of Lake Cadagno

Frontiers in Earth Science, 2022
Although lake sediments are globally important organic carbon sinks and therefore important habitats for deep microbial life, the deep lacustrine biosphere has thus far been little studied compared to its marine counterpart.

Genomes of three bacteriophages from the deep subsurface aquifer

Data in Brief, 2019
Viral particles have been detected in the underground biosphere where they could be one of the main factors impacting microbial diversity, biogeochemistry and evolution.

Deglacial carbon cycle changes observed in a compilation of 127 benthic δ¹³C time series (20–6 ka) [PDF]

Climate of the Past, 2018
We present a compilation of 127 time series δ13C records from Cibicides wuellerstorfi spanning the last deglaciation (20–6 ka) which is well-suited for reconstructing large-scale carbon cycle changes, especially for comparison with isotope ...

Cultural Values of Landscapes in the Practical Work of Biosphere Reserves

Land, 2023
The purpose of this paper is to investigate the role of the landscape’s cultural values in the practical work of biosphere reserves and to identify what opportunities there are to increase awareness and knowledge about these values.

Microbial diversity of drilling fluids from 3000 m deep Koyna pilot borehole provides insights into the deep biosphere of continental earth crust

, 2020
. Scientific deep drilling of the Koyna pilot borehole into the continental crust up to a depth of 3000 m below the surface at the Deccan Traps, India, provided a unique opportunity to explore microbial life within the deep granitic bedrock of the ...

Rapid metabolism fosters microbial survival in the deep, hot subseafloor biosphere

Nature Communications, 2022
A fourth of the global seabed sediment volume is buried at depths where temperatures exceed 80 °C, a previously proposed thermal barrier for life in the subsurface.

Revealing the full biosphere structure and versatile metabolic functions in the deepest ocean sediment of the Challenger Deep

Genome Biology, 2021
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. We adopt a deep metagenomics approach to
