Marine nitrogen fixation: what's the fuss?

Abstract:

:Biological nitrogen fixation is a much more important process in the nitrogen cycle of the oceans than previously thought. Further, nitrogen fixation may have an influence on the capacity of the oceans to sequester carbon. A greater diversity of marine nitrogen fixers has also been uncovered but their quantitative significance remains to be determined.
