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

The pelagic realm of the dark ocean represents a key site for remineralization of organic
matter and long‐term carbon storage and burial in the biosphere. It contains the largest pool …

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 …

Microbial communities of the Arctic Ocean are poorly characterized in comparison to other
aquatic environments as to their horizontal, vertical, and temporal turnover. Yet, recent …

One of the major conundrums in oceanography for the past 20 y has been that, although the
total flux of dissolved organic carbon (OC; DOC) discharged annually to the global ocean …

The discovery of ammonia oxidation by mesophilic and thermophilic Crenarchaeota and the
widespread distribution of these organisms in marine and terrestrial environments indicated …

Nitrification plays an important role in marine biogeochemistry, yet efforts to link this process
to the microorganisms that mediate it are surprisingly limited. In particular, ammonia …

Heterotrophic bacteria are the most abundant organisms on the planet and dominate
oceanic biogeochemical cycles, including that of carbon. Their role in polar waters has been …

Despite the high abundance of Archaea in the global ocean, their metabolism and
biogeochemical roles remain largely unresolved. We investigated the population dynamics …

Ammonia-oxidizing archaea (AOA) are thought to be among the most abundant
microorganisms on Earth and may significantly impact the global nitrogen and carbon …
