New data force us to raise previous estimates of oceanic denitrification. Our revised estimate of ~ 450 Tg N yr -1 (Tg = 10 12 g) produces an oceanic fixed N budget with a large deficit (~ 200 Tg N yr -1 ) that can be explained only by positing an ocean that has deviated far from a steady-state, the need for a major upwards revision of fixed N inputs, particularly nitrogen fixation, or both. Oceanic denitrification can be significantly altered by small re-distributions of carbon and dissolved…

Constraints on oceanic N balance/imbalance from sedimentary 15 N records
Abstract. According to current best estimates, the modern ocean's N cycle is in severe deficit. N isotope budgeting provides an independent geochemical constraint in this regard as well as the only
Oceanic nitrogen cycling and N2O flux perturbations in the Anthropocene
There is currently no consensus on how humans are affecting the marine nitrogen (N) cycle, which limits marine biological production and CO2 uptake. Anthropogenic changes in ocean warming,
Marine denitrification rates determined from a global 3-D inverse model
A major impediment to understanding long-term changes in the marine nitrogen (N) cycle is the persistent un- certainty about the rates, distribution, and sensitivity of its largest fluxes in the
Isotopic constraints on the pre-industrial oceanic nitrogen budget
The size of the bio-available (i.e. "fixed") nitrogen inventory in the ocean influences global marine productivity and the biological carbon pump. Despite its importance, the pre-industrial rates for
The dynamics of the marine nitrogen cycle across the last deglaciation
[1] We use a geochemical box model to investigate the changes in marine N-fixation and denitrification required to match the observed sedimentary δ15N changes between ∼ 30 kyr B.P. and the late
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.
Iron availability limits the ocean nitrogen inventory stabilizing feedbacks between marine denitrification and nitrogen fixation
It is suggested that iron is the ultimate limiting nutrient leading to nitrogen being the proximate limiting nutrient over wide regions today, leading to a higher marine N inventory, increased export production, and perhaps widespread phosphorus limitation of the phytoplankton community.
Modeling the impact of iron and phosphorus limitations on nitrogen fixation in the Atlantic Ocean
Abstract. The overarching goal of this study is to simulate subsurface N* (sensu, Gruber and Sarmiento, 1997; GS97) anomaly patterns in the North Atlantic Ocean and determine the basin wide rates of


A large source of atmospheric nitrous oxide from subtropical North Pacific surface waters
Nitrous oxide (N2O), a trace gas whose concentration is increasing in the atmosphere, plays an important role in both radiative forcing and stratospheric ozone depletion,. Its biogeochemical cycle
Global patterns of marine nitrogen fixation and denitrification
A new quasi‐conservative tracer N*, defined as a linear combination of nitrate and phosphate, is proposed to investigate the distribution of nitrogen fixation and denitrification in the world oceans.
Atmospheric inputs of dissolved organic nitrogen to the oceans
THE input of fixed nitrogen to the oceans by in situ fixation, river/groundwater supply and atmospheric deposition represents an important control on marine productivity on long timescales, and hence

Despite its importance for the global oceanic nitrogen (N) cycle, considerable uncertainties exist about the N fluxes of the Arabian Sea. On the basis of our recent measurements during the German

The rate and factors controlling denitrification in marine sediments have been investigated using a prognostic diagenetic model. The model is forced with observed carbon fluxes, bioturbation and
An assessment of nitrogen fixation as a source of nitrogen to the North Atlantic Ocean
The role of nitrogen fixation in the nitrogen cycle of the North Atlantic basin was re-evaluated because recent estimates had indicated a far higher rate than previous reports. Examination of the

INTEREST in nitrous oxide (N2O) has increased considerably in the light of its deleterious effect on the ozone layer1, and contribution to the greenhouse effect2. There are many sources of

CHANGES in ocean chemistry and circulation have been invoked to explain the lower atmospheric CO2 concentrations of glacial periods observed in ice-core records1. The processes that modulate these

Recent studies of marine nitrons oxide have focused attention on the suboxic and low‐oxygen zones associated with ocean basin eastern boundaries. It has been suggested that complex N2O cycling

In the absence of human activities, biotic fixation is the primary source of reactive N, providing about 90–130 Tg N yr−1 (Tg = 1012 g) on the continents. Human activities have resulted in the
