Figure 1. Observations of (a) [Al diss ] (nmol kg −1 ) and (b) [ Si diss ] (µmol kg −1 ) at the West Atlantic GEOTRACES transect (Middag et al., 2014)
Figure 2. Beam attenuation coefficient, a measure of the amount of particles (e.g. Behrenfeld et al., 2006)
Figure 3. Aluminium cycling in the ocean. Dissolved Al enters the ocean through the release of Al diss from deposited dust and resuspended sediments, while rivers, hydrothermal vents and reducing sediments are negligible sources of Al diss
