Biotic and abiotic surfaces in marine waters are rapidly colonized by microorganisms.
Surface colonization and subsequent biofilm formation and development provide numerous …

The “biological pump” is the process by which photosynthetically-produced organic matter in
the ocean descends from the surface layer to depth by a combination of sinking particles …

A census of the biomass on Earth is key for understanding the structure and dynamics of the
biosphere. However, a global, quantitative view of how the biomass of different taxa …

Deep-sea microbial communities are exposed to high-pressure conditions, which has a
variable impact on prokaryotes depending on whether they are piezophilic (that is, pressure …

Hadal oceans at water depths below 6,000 m are the least-explored aquatic biosphere. The
Challenger Deep, located in the western equatorial Pacific, with a water depth of∼ 11 km, is …

A fraction of the carbon captured by phytoplankton in the sunlit surface ocean sinks to depth
as dead organic matter and faecal material. The microbial breakdown of this material in the …

In the bathypelagic realm of the ocean, the role of marine snow as a carbon and energy
source for the deep-sea biota and as a potential hotspot of microbial diversity and activity …

The oceanic waters below a depth of 200 m represent, in terms of volume, the largest habitat
of the biosphere, harboring approximately 70% of the prokaryotic biomass in the oceanic …

Bacterial assemblages from subsurface (100 m depth), meso‐(200–1000 m depth) and
bathy‐pelagic (below 1000 m depth) zones at 10 stations along a North Atlantic Ocean …

Sinking particles mediate the transport of carbon and energy to the deep-sea, yet the
specific microbes associated with sedimenting particles in the ocean's interior remain largely …
