The ocean is home to a diverse and metabolically versatile microbial community that
performs the complex biochemical transformations that drive the nitrogen cycle, including …

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 …

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

The marine nitrogen (N) cycle controls the productivity of the oceans. This cycle is driven by
complex biogeochemical transformations, including nitrogen fixation, denitrification, and …

Of all the biogeochemical cycles, nitrogen is the one most intimately and thoroughly
associated with microbes. Essential and unique steps in the nitrogen cycle are performed by …

The marine nitrogen cycle is perhaps the most complex and therefore the most fascinating
among all biogeochemical cycles in the sea. As a limiting element for biological productivity …

The nitrogen (N) cycle is composed of multiple transformations of nitrogenous compounds,
catalyzed primarily by microbes. The N cycle controls the availability of nitrogenous nutrients …

The surface water of the marine environment has traditionally been viewed as a nitrogen (N)
limited habitat, and this has guided the development of conceptual biogeochemical models …

Atmospheric reactions and slow geological processes controlled Earth's earliest nitrogen
cycle, and by~ 2.7 billion years ago, a linked suite of microbial processes evolved to form the …

Nitrification, the oxidation of ammonia via nitrite to nitrate, is a key process in marine
nitrogen (N) cycling. Although oceanic ammonia and nitrite oxidation are balanced …
