- Abstract:
- This study proposes to advance the use of silicon isotope natural abundances (delta30Si) as a palaeoceanographic and biogeochemical tool by developing a method for measuring delta30Si by MC-ICP-MS and verifying that delta30Si of biogenic opal tracks the utilization of silicic acid during a diatom bloom. Measurement of delta30Si by MC-ICP-MS should be faster, less hazardous, equally or more precise, and open to a wider number of researchers than current methods. Once a MC-ICP-MS protocol for delta30Si has been worked out to a precision of plus/minus 0.1? or better, diatom blooms will be grown in laboratory mesocosms, and delta30Si of silicic acid and biogenic opal will be tracked as silicic acid stocks are drawn down to zero in support of biological production.
