Boron isotopes and trace elements experimental data of tropical corals

Expand/Collapse All

Description

Boron isotopes and trace element data (Li/Ca, B/Ca, Mg/Ca, Sr/Ca) for corals Pocillopora damicornis and Stylophora pistillata cultured under scenarios of ocean acidification and warming temperature. Calculated internal parameters of the calcifying medium (pHcf, [CO32-]cf, DICcf) are also presented.

Methods & Sampling

Boron isotopes were measured at the University of Cambridge (Cambridge, UK) utilizing an MC-ICP-MS Neptune+ equipped with 10^13 ohm amplifiers technology (Lloyd et al., 2018). Boron purification was realized by microdistillation (Wang et al., 2010, Misra et al., 2014b). Uncertainties (2sd) are calculated based on replicates of standard AE121 δ11B measurements for an analytical session.

Trace elements were measured on an Element XR at the IUEM (Plouzané, France), method is detailed in Guillermic et al., in prep (Biogeosciences). Uncertainties (2sd) are calculated based on replicates of an in-house standard CamWuellestorfi (Misra et al.,2014a) for an analytical session.

Data Processing Description

pHcf, DICcf and [CO32-]cf were calculated based on δ11B and B/Ca data utilizing the Matlab© code provided by DeCarlo et al., (2018), adapted for various δ11Bsw and using a KD of McCulloch et al., 2017.

BCO-DMO Processing Notes:
- added conventional header with dataset name, PI name, version date
- modified parameter names to conform with BCO-DMO naming conventions
- replaced spaces with undrscores in species names.
