Prokaryotic life has dominated most of the evolutionary history of our planet, evolving to
occupy virtually all available environmental niches. Extremophiles, especially those thriving …

Organic carbon in marine sediments is a critical component of the global carbon cycle, and
its degradation influences a wide range of phenomena, including the magnitude of carbon …

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 …

The sinking of organic particles formed in the photic layer is a main vector of carbon export
into the deep ocean. Although sinking particles are heavily colonized by microbes, so far it …

Marine viruses are key drivers of host diversity, population dynamics and biogeochemical
cycling and contribute to the daily flux of billions of tons of organic matter. Despite recent …

Vast regions of the dark ocean have ultra-slow rates of organic matter sedimentation, and
their sediments are oxygenated to great depths yet have low levels of organic matter and …

Community dynamics are central in microbial ecology, yet we lack studies comparing
diversity patterns among marine protists and prokaryotes over depth and multiple years …

Bacterial and archaeal communities inhabiting the subsurface seabed live under strong
energy limitation and have growth rates that are orders of magnitude slower than laboratory …

Hadal trench bottom (> 6000 m below sea level) sediments harbor higher microbial cell
abundance compared with adjacent abyssal plain sediments. This is supported by the …

In recent years, the global carbon cycle has garnered significant research attention.
However, details of the intricate relationship between planktonic bacteria, hydrochemistry …
