Nitrogen (N) is used in many of life's fundamental biomolecules, and it is also a participant in
environmental redox chemistry. Biogeochemical processes control the amount and form of N …

The way that nutrients cycle through atmospheric, terrestrial, oceanic and associated biotic
reservoirs can constrain rates of biological production and help structure ecosystems on …

Cyanobacteria are the Earth's oldest (∼ 3.5 bya) oxygen evolving organisms, and they have
had major impacts on shaping our modern-day biosphere. Conversely, biospheric …

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 …

A climatological mean distribution for the surface water pCO2 over the global oceans in non-
El Niño conditions has been constructed with spatial resolution of 4°(latitude)× 5°(longitude) …

Biological N2 fixation is an important part of the marine nitrogen cycle as it provides a source
of new nitrogen that can support biological carbon export and sequestration. Research in …

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

Discrepancies between estimates of oceanic N 2 fixation and nitrogen (N) losses through
denitrification have focused research on identifying N 2-fixing cyanobacteria and quantifying …

Nitrogen (N) is a key element for life in the oceans. It controls primary productivity in many
parts of the global ocean, consequently playing a crucial role in the uptake of atmospheric …

Cyanobacteria have gained a lot of attention in recent years because of their potential
applications in biotechnology. We present an overview of the literature describing the uses …
