Multiple natural and anthropogenic processes alter the carbonate chemistry of the coastal
zone in ways that either exacerbate or mitigate ocean acidification effects. Freshwater inputs …

Biological dinitrogen (N2) fixation supplies nitrogen to the oceans, supporting primary
productivity, and is carried out by some bacteria and archaea referred to as diazotrophs …

Marine diazotrophs convert dinitrogen (N 2) gas into bioavailable nitrogen (N), supporting
life in the global ocean. In 2012, the first version of the global oceanic diazotroph database …

The ocean's nitrogen cycle is driven by complex microbial transformations, including
nitrogen fixation, assimilation, nitrification, anammox and denitrification. Dinitrogen is the …

Biological dinitrogen fixation provides the largest input of nitrogen to the oceans, therefore
exerting important control on the ocean's nitrogen inventory and primary productivity …

The dominant process adding nitrogen (N) to the ocean, di-nitrogen (N2) fixation, is
mediated by prokaryotes (diazotrophs) sensitive to a variety of environmental factors. In …

Nitrogen‐fixing microorganisms (diazotrophs) provide biologically available nitrogen to
plankton communities and thereby greatly influence the productivity in many marine regions …

The high diversity and global distribution of heterotrophic bacterial diazotrophs (HBDs) in
the ocean has recently become apparent. However, understanding the role these largely …

Results of recent modelling efforts imply denitrification‐influenced waters, such as those in
the E astern T ropical S outh P acific (ETSP), may support high rates of biological nitrogen …

In addition to the cyanobacterial N2-fixers (diazotrophs), there is a high nifH gene diversity of
non-cyanobacterial groups present in marine environments, yet quantitative information …
