Effect of natural iron fertilization on carbon sequestration in the Southern Ocean
The availability of iron limits primary productivity and the associated uptake of carbon over large areas of the ocean. Iron thus plays an important role in the carbon cycle, and changes in itsExpand

Growth rates of large and small Southern Ocean diatoms in relation to availability of iron in natural seawater
Blooms of large diatoms dominate the CO2 drawdown and silicon cycle of the Southern Ocean in both the past and present. The growth of these Antarctic diatoms is limited by availability of iron (andExpand

Southern Ocean control of silicon stable isotope distribution in the deep Atlantic Ocean
The fractionation of silicon (Si) stable isotopes by biological activity in the surface ocean makes the stable isotope composition of silicon (delta Si-30) dissolved in seawater a sensitive tracer ofExpand

The Distribution of Dissolved Iron in the West Atlantic Ocean
Iron (Fe) is an essential trace element for marine life. Extremely low Fe concentrations limit primary production and nitrogen fixation in large parts of the oceans and consequently influence oceanExpand

Neodymium isotopic composition and concentration in the western North Atlantic Ocean: Results from the GEOTRACES GA02 section
The neodymium (Nd) isotopic composition of seawater is commonly used as a proxy to study past changes in the thermohaline circulation. The modern database for such reconstructions is however poor andExpand

Co-limitation by iron and light of Chaetoceros brevis, C. dichaeta and C. calcitrans (Bacillariophyceae)
The interaction between iron and light limitation was investigated in 3 marine diatom species: 2 Antarctic diatom isolates, Chaetoceros brevis and C. dichaeta, and an isolate from temper- ate waters,Expand

Kinetic study reveals weak Fe-binding ligand, which affects the solubility of Fe in the Scheldt estuary
The chemistry of dissolved Fe(III) was studied in the Scheldt estuary (The Netherlands). Two discrete size fractions of the dissolved bulk (<0.2 μm and <1 kDa) were considered at three salinitiesExpand

Effect of trace metal availability on coccolithophorid calcification
The deposition of atmospheric dust into the ocean has varied considerably over geological time. Because some of the trace metals contained in dust are essential plant nutrients which can limitExpand

Speciation of Fe in the Eastern North Atlantic Ocean
In the Eastern North Atlantic Ocean iron (Fe) speciation was investigated in three size fractions: the dissolvable from unfiltered samples, the dissolved fraction (o 0.2 mm) and the fraction smallerExpand
