Weighing the deep continental biosphere [PDF]
FEMS Microbiology Ecology, 2013 There is abundant evidence for widespread microbial activity in deep continental fractures and aquifers, with important implications for biogeochemical cycling on Earth and the habitability of other planetary bodies. Whitman et al. (P Natl Acad Sci USA, 95, 1998, 6578) estimated a continental subsurface biomass on the order of 10(16) -10(17) g C.

The hadal zone is an important and heterogeneous sink of black carbon in the ocean
Communications Earth & Environment, 2022 Black carbon accumulation rates in hadal trenches in the deepest regions of the oceans could be seven-fold higher than the global ocean average, according to geochemical and isotopic analyses of sediments from six trenches in the Pacific Ocean.

The lifetime of excess atmospheric carbon dioxide [PDF]
, 1994 We explore the effects of a changing terrestrial biosphere on the atmospheric residence time of CO2 using three simple ocean carbon cycle models and a model of global terrestrial carbon cycling.

Tracking the Deep Biosphere through Time
Geosciences, 2020 The oceanic and continental lithosphere constitutes Earth’s largest microbial habitat, yet it is scarcely investigated and not well understood. The physical and chemical properties here are distinctly different from the overlaying soils and the ...

Choice Reviews Online, 1999 The first inhabitants of planet Earth were single‐celled microorganisms and they are still with us today. Their name is truly legion, for they live everywhere, from boiling hot springs at the Earth's surface and on the seafloor to the coldest waters of the oceans and the Antarctic lakes.
