| m) concentrations of Al, Sr, Ba, Mn, Rare Earth Elements (REE) and Th isotopes were determined over time. We obtain percentages of dissolution in agreement with the general knowledge about the solubility of these tracers: Th approximate to Al < Heavy REE < Light REE < Mn < Ba < Sr. For Mn and Ce, precipitation/adsorption occurs at the end of the experiment probably due to their oxidation as insoluble oxides. Particulate residence time of the tracers ranged from less than 1 day to 10-14 days. During the experiment, biological activity has a control on the dissolution process through the remineralization of particulate organic carbon, In the 30 m experiment, the observed dissolution of aragonite indicates that the pH of the incubation solution... |
