“…In and near the Indonesian Archipelago [Al diss ] ranges from 1 to 20 nM in both models, while the observations of Obata et al (2007) and Slemons et al (2010) are much more homogeneous, about 10 nM. This might be because the ocean currents in both models are not realistic because of a too low resolution of our model for this region.…”

International audienceA model of aluminium has been developed and implemented in an Ocean General Circulation Model (NEMO-PISCES). In the model, aluminium enters the ocean by means of dust deposition. The internal oceanic processes are described by advection, mixing and reversible scavenging. The model has been evaluated against a number of selected high-quality datasets covering much of the world ocean, especially those from the West Atlantic Geotraces cruises of 2010 and 2011. Generally, the model results are in fair agreement with the observations. However, the model does not describe well the vertical distribution of dissolved Al in the North Atlantic Ocean. The model may require changes in the physical forcing and the vertical dependence of the sinking velocity of biogenic silica to account for other discrepancies. To explore the model behaviour, sensitivity experiments have been performed, in which we changed the key parameters of the scavenging process as well as the input of aluminium into the ocean. This resulted in a better understanding of aluminium in the ocean, and it is now clear which parameter has what effect on the dissolved aluminium distribution and which processes might be missing in the model, among which boundary scavenging and biological incorporation of aluminium into diatoms

“…In this way Al diss is distributed over depth more efficiently than due to mixing and water mass transport. Aluminium is scavenged relatively efficiently and therefore has a relatively short residence time in the ocean (100-200 yr) (Orians and Bruland, 1985).…”

“…In addition to Mn, other trace elements can be similarly released from margin sediments via redox mobilization, including Co (Noble et al, 2012(Noble et al, , 2017Hawco et al, 2016;Tagliabue et al, 2018) and Ce (Zhang and Nozaki, 1998;Obata et al, 2007;Zheng et al, 2016). While Co also undergoes similar redox cycling in seawater, both reduced and oxidized forms can exist in the soluble phase (Moffett and Ho, 1996), often through stabilization with organic ligands (Saito and Moffett, 2001;Hawco et al, 2016Hawco et al, , 2018Noble et al, 2017;Tagliabue et al, 2018).…”

Shelf Inputs and Lateral Transport of Mn, Co, and Ce in the Western North Pacific Ocean

et al. 2019

The margin of the western North Pacific Ocean releases redox-active elements like Mn, Co, and Ce into the water column to undergo further transformation through oxide formation, scavenging, and reductive dissolution. Near the margin, the upper ocean waters enriched in these elements are characterized by high dissolved oxygen, low salinity, and low temperature, and are a source of the North Pacific Intermediate Water. High dissolved concentrations are observed across the Western Subarctic Gyre, with a rapid decrease in concentrations away from the margin and across the subarcticsubtropical front. The particulate concentrations of Mn, Co, and Ce are also high in the subarctic surface ocean and enriched relative to Ti and trivalent rare earth elements. Furthermore, the particles enriched in Mn, Co, and Ce coincide at the same depth range, suggesting that these elemental cycles are coupled through microbial oxidation in the subarctic gyre as the waters travel along the margin before being subducted at the subarctic-subtropical front. Away from the margin, the Mn, Co, and Ce cycles decouple, as Mn and Ce settle out as particles while dissolved Co is preserved and transported within the North Pacific Intermediate Water into the central North Pacific Ocean.

“…Hence, sedimenting Al associated with Si biog is a more obvious candidate for the sediment source of Al diss . The scavenger and incorporator of Al, Si biog , is mostly present alongside active diatom production: north of 44 • N and south of 40 • S (Nelson et al, 1995;Tréguer and De La Rocha, 2013). Therefore, in these regions this prerequisite is satisfied.…”

On the effects of circulation, sediment resuspension and biological incorporation by diatoms in an ocean model of aluminium*

et al. 2014

The distribution of dissolved aluminium in the West Atlantic Ocean shows a mirror image with that of dissolved silicic acid, hinting at intricate interactions between the ocean cycling of Al and Si. The marine biogeochemistry of Al is of interest because of its potential impact on diatom opal remineralisation, hence Si availability. Furthermore, the dissolved Al concentration at the surface ocean has been used as a tracer for dust input, dust being the most important source of the bio-essential trace element iron to the ocean. Previously, the dissolved concentration of Al was simulated reasonably well with only a dust source, and scavenging by adsorption on settling biogenic debris as the only removal process. Here we explore the impacts of (i) a sediment source of Al in the Northern Hemisphere (especially north of ∼40 • N), (ii) the imposed velocity field, and (iii) biological incorporation of Al on the modelled Al distribution in the ocean. The sediment source clearly improves the model results, and using a different velocity field shows the importance of advection on the simulated Al distribution. Biological incorporation appears to be a potentially important removal process. However, conclusive independent data to constrain the Al : Si incorporation ratio by growing diatoms are missing. Therefore, this study does not provide a definitive answer to the question of the relative importance of Al removal by incorporation compared to removal by adsorptive scavenging.
