Marine dissolved organic matter (DOM) contains more carbon than the combined stocks of
Earth's biota. Organisms in the ocean continuously release a myriad of molecules that …

The seabed plays a key role in the marine carbon cycle as a) the terminal location of aerobic
oxidation of organic matter, b) the greatest anaerobic bioreactor, and c) the greatest …

Microbial life in marine sediment contributes substantially to global biomass and is a crucial
component of the Earth system. Subseafloor sediment includes both aerobic and anaerobic …

Across the tree of life, populations have evolved the capacity to contend with suboptimal
conditions by engaging in dormancy, whereby individuals enter a reversible state of reduced …

Hadal trenches are the deepest and most remote regions of the ocean. The 11-kilometer
deep Challenger Deep is the least explored due to the technical challenges of sampling …

In‐depth knowledge about spatial and temporal variation in microbial diversity and function
is needed for a better understanding of ecological and evolutionary responses to global …

Previous studies of microbial communities in subseafloor sediments reported that microbial
abundance and diversity decrease with sediment depth and age, and microbes dominating …

Despite the recent increase in knowledge concerning microorganisms, the processes
determining their global distribution and functioning have not been disentangled. Microbial …

Water is the cellular milieu, drives all biochemistry within Earth's biosphere and facilitates
microbe‐mediated decay processes. Instead of reviewing these topics, the current article …

The deep biosphere is the largest microbial habitat on Earth and features abundant bacterial
endospores. Whereas dormancy and survival at theoretical energy minima are hallmarks of …
