Chapter 4 – Nitrogen Fixation in the Marine Environment This chapter first summarizes the recent advances and insights relative to nitrogen (N 2 ) fixation in benthic marine environments, move on to the water column, then summarizes controls on N 2 fixation and comments on the broader, bioge....
Many marine organisms have coevolved symbiotic relationships with nitrogen-fixing bacteria in nitrogen limited environments such as coral reefs. In addition, some of these organisms also harbor microbes that carry out nitrification and denitrification. Prokaryotes involved in nitrogen fixation and other nitr...
Diazotrophs can supply new nitrogen to the marine environment via nitrogen (N2) fixation, relieving nitrogen limitation. The distributions of diazotrophs and N2 fixation have been hypothesized to be generally controlled by temperature, phosphorus, and iron availability in the global ocean. However, even...

Nitrogen (N2) fixation in oligotrophic surface waters is the main source of new nitrogen to the ocean1 and has a key role in fuelling the biological carbon pump2. Oceanic N2 fixation has been attributed almost exclusively to cyanobacteria, even though ge
The ocean's nitrogen cycle is driven by complex microbial transformations, including nitrogen fixation, assimilation, nitrification, anammox and denitrification. Dinitrogen is the most abundant form of nitrogen in sea water but only accessible by nitrogen-fixing microbes. Denitrification and nitrification ar...
Researchers have recognized growing imbalance between new nitrogen (N) inputs and N losses in the marine environment through human activities, especially in estuarine and coastal waters where N overenrichment has fueled accelerated primary production, or eutrophication, which is an increase in the rate...
