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 evaluate the scale of human perturbation of these fluxes. Fluvial inputs dominate inputs to the continental shelf, and we estimate that about 75% of this fluvial nitrogen escapes from the shelf to the open ocean. Biological dinitrogen fixation is the main external source of nitrogen to the open ocean, i.e… 

Ocean Ammonia Outgassing: Modulation by CO2 and Anthropogenic Nitrogen Deposition

The imprint of anthropogenic activities on the marine nitrogen (N) cycle remains challenging to represent in global models, in part because of uncertainties regarding the source of marine N to the

Natural forcing of the North Atlantic nitrogen cycle in the Anthropocene

An ∼130-year-long record of the 15N/14N of skeleton-bound organic matter in a coral from the outer reef of Bermuda provides a test of the hypothesis that anthropogenic atmospheric nitrogen has significantly augmented the nitrogen supply to the open North Atlantic surface ocean.

Observation- and Model-Based Estimates of Particulate Dry Nitrogen Deposition to the Oceans.

Anthropogenic nitrogen (N) emissions to the atmosphere have increased significantly the deposition of nitrate (NO3-) and ammonium (NH4+) to the surface waters of the open ocean, with potential

The Southern Ocean with the largest uptake of anthropogenic nitrogen into the ocean interior

A new method is developed to assess the change in the oceanic uptake of N ex (ΔN ex ) in the entire Southern Ocean, and the spatiotemporal distribution of ΔN ex in the SO is obtained by applying this method to a high-resolution grid data constructed using ship-based observations.

Anthropogenic Perturbations of the Carbon and Nitrogen Cycles in the East Sea (Sea of Japan)

The dynamic overturning circulation in the East Sea facilitates the absorption of anthropogenic CO2 by effectively transporting it from the surface to the interior of the sea. However, recent

21st-century rise in anthropogenic nitrogen deposition on a remote coral reef

In a coral core from Dongsha Atoll, a remote coral reef ecosystem, a decline in the 15N/14N of coral skeleton–bound organic matter is observed, which signals increased deposition of anthropogenic atmospheric N on the open ocean and its incorporation into plankton and, in turn, the atoll corals.

Competing and accelerating effects of anthropogenic nutrient inputs on climate-driven changes in ocean carbon and oxygen cycles.

Nutrient inputs from the atmosphere and rivers to the ocean are increased substantially by human activities. However, the effects of increased nutrient inputs are not included in the widely used

Global Marine N2 Fixation Estimates: From Observations to Models

It is suggested that a more comprehensive understanding of the environmental and ecological interaction of marine N2 fixers is required to advance the field toward robust N2 fixation rates estimates and predictions.

The anthropogenic perturbation of the marine nitrogen cycle by atmospheric deposition: Nitrogen cycle feedbacks and the 15N Haber‐Bosch effect

Over the last 100 years, anthropogenic emissions have led to a strong increase of atmospheric nitrogen deposition over the ocean, yet the resulting impacts and feedbacks are neither well understood

Marine biogenic source of atmospheric organic nitrogen in the subtropical North Atlantic

It is found that the organic nitrogen in marine aerosols derives predominantly from biological production in the surface ocean rather than from pollution on land, indicating that the ocean is not a passive recipient of anthropogenic nitrogen deposition, as it has previously been considered.

The marine nitrogen cycle: recent discoveries, uncertainties and the potential relevance of climate change

A nitrogen budget for the coastal and open ocean, where inputs and outputs match rather well, is presented and predicted climate change will impact the expansion of the oceans' oxygen minimum zones, the productivity of surface waters and presumably other microbial processes, with unpredictable consequences for the cycling of nitrogen.

Quantifying the impact of anthropogenic nitrogen deposition on oceanic nitrous oxide

Anthropogenically induced increases in nitrogen deposition to the ocean can stimulate marine productivity and oceanic emission of nitrous oxide. We present the first global ocean model assessment of

Atmospheric deposition of nutrients and excess N formation in the North Atlantic

Abstract. Anthropogenic emissions of nitrogen (N) to the atmosphere have been strongly increasing during the last century, leading to greater atmospheric N deposition to the oceans. The North

Impacts of Atmospheric Anthropogenic Nitrogen on the Open Ocean

Although ∼10% of the ocean's drawdown of atmospheric anthropogenic carbon dioxide may result from this atmospheric nitrogen fertilization, leading to a decrease in radiative forcing, up to about two-thirds of this amount may be offset by the increase in N2O emissions.

Impacts of atmospheric nutrient inputs on marine biogeochemistry

The primary nutrients that limit marine phytoplankton growth rates include nitrogen (N), phosphorus (P), iron (Fe), and silicon (Si). Atmospheric transport and deposition provides a source for each
