Changing perspectives in marine nitrogen fixation
Changing views and a changing ocean As a component of many biomolecules, nitrogen is a crucial element for life, especially in nutrient-poor environs such as the open ocean. Atmospheric dinitrogen gas (N 2 ) is abundant but must be fixed by reduction to ammonia, a process limited to certain organism...

Changing views and a changing ocean As a component of many biomolecules, nitrogen is a crucial element for life, especially in nutrient-poor environs such as the open ocean.
