Importance of salt fingering for new nitrogen supply in the oligotrophic ocean
Explore this paper's citation graph
Summary
With measurements across the tropical and subtropical Atlantic, Pacific and Indian oceans, it is shown that nitrate diffusion dominates over N2 fixation and should be considered in present and future ocean nitrogen budgets, as it could supply globally 0.23–1.00 Tmol N yr−1 to the euphotic zone.
