Modelling iron limitation in the North Pacific
نویسندگان
چکیده
The subarctic North Pacific is one of three major high nitrate, low chlorophyll (HNLC) oceanic regions, along with the Southern Ocean and the eastern equatorial Pacific. In these regions, uptake of nitrogen by phytoplankton is widely thought to be regulated by the availability of dissolved iron. The supply of dissolved iron is twofold: via atmospheric deposition of dust and via upward transport of dissolved iron from the ocean interior to the surface euphotic layer. In the subarctic North Pacific, atmospheric deposition has been considered to be the dominant source, despite little compelling evidence.

Phosphate depletion in the western North Atlantic Ocean.
Surface waters of the subtropical Sargasso Sea contain dissolved inorganic phosphate (DIP) concentrations of 0.2 to 1.0 nanomolar, which are sufficiently low to result in phosphorus control of primary production. The DIP concentrations in this area (which receives high inputs of iron-rich dust from arid regions of North Africa) are one to two orders of magnitude lower than surface levels in the...
متن کاملNitrogen isotope simulations show the importance of atmospheric iron deposition for nitrogen fixation across the Pacific Ocean
observations, to constrain the pattern of N2 fixation across the Pacific Ocean. N2 fixation introduces isotopically light atmospheric N2 from to the ocean (d N = 0‰) relative to the oceanic average near 5‰, which makes nitrogen isotopes suitable to infer patterns of N2 fixation. Including atmospheric iron limitation of diazotrophy in the model shifts the pattern of simulated N2 fixation from th...
متن کاملBiogeochemical modelling of the tropical Pacific Ocean . II : Iron biogeochemistry
A coupled physical–biogeochemical model of the tropical Pacific Ocean with simultaneous iron and nitrogen limitation was developed to study questions of iron biogeochemistry, its effects on upper ocean production, and ultimately the biogeochemical cycles of the other elements. The model results suggest that iron limitation is ubiquitous in the equatorial Pacific, and extends further west than i...
متن کاملAssessment of relative phosphorus limitation of Trichodesmium spp. in the North Pacific, North Atlantic, and the north coast of Australia
Trichodesmium spp. is a colonial diazotrophic cyanobacterium that occurs in the oligotrophic tropics and subtropics. Because of its ability to fix atmospheric N2, it is likely to be growth limited by P or Fe, and it has been hypothesized that limitation differs among different ocean basins. Two assays used as indices of P limitation or stress in Trichodesmium spp. are uptake of PO 4 to determin...
متن کاملImpacts of increasing anthropogenic soluble iron and nitrogen deposition on ocean biogeochemistry
[1] We present results from transient sensitivity studies with the Biogeochemical Elemental Cycling (BEC) ocean model to increasing anthropogenic atmospheric inorganic nitrogen (N) and soluble iron (Fe) deposition over the industrial era. Elevated N deposition results from fossil fuel combustion and agriculture, and elevated soluble Fe deposition results from increased atmospheric processing in...
