- Abstract:
- The trace metal content of all carbonate proxies shows a biologically controlled signature, which is distinctive from inorganic precipitates. Our aim is to gain a mechanistic understanding of this biological influence on trace metal incorporation during biomineralisation. This insight is critical for the precise application of these proxies to reconstruct past ocean conditions and climate. We will combine geochemical analyses (Sr/Ca, stable Sr and Ca isotopes) with element-specific spectroscopic analysis and nanoscale chemical mapping of Sr in inorganic and coccolithophore calcite grown under varied laboratory conditions. These results will define whether discrimination between the similarly sized Sr and Ca ions occurs during biological Ca transport to the site of mineralisation, or during the crystal growth, and will develop a new suite of Ca and Sr proxies.
