Global nitrogen cycle: critical enzymes, organisms, and processes for nitrogen budgets and dynamics
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 …

Upper ocean biogeochemistry of the oligotrophic North Pacific Subtropical Gyre: from nutrient sources to carbon export
Abstract Subtropical gyres cover 26%–29% of the world's surface ocean and are
conventionally regarded as ocean deserts due to their permanent stratification, depleted …

A reevaluation of the magnitude and impacts of anthropogenic atmospheric nitrogen inputs on the ocean
TD Jickells, E Buitenhuis, K Altieri… - Global …, 2017 - Wiley Online Library
We report a new synthesis of best estimates of the inputs of fixed nitrogen to the world ocean
via atmospheric deposition and compare this to fluvial inputs and dinitrogen fixation. We …

[HTML][HTML] Nutrients that limit growth in the ocean
Phytoplankton form the basis of the marine food web and are responsible for approximately
half of global carbon dioxide (CO2) fixation (∼ 50 Pg of carbon per year). Thus, these …

Nutrient regulation of biological nitrogen fixation across the tropical western North Pacific
Nitrogen fixation is critical for the biological productivity of the ocean, but clear mechanistic
controls on this process remain elusive. Here, we investigate the abundance, activity, and …
