Seasonal changes in the boron isotopic signature and boron to calcium ratio (B/Ca) of corals at Rottnest Island. (a,b) Seasonal time-series of δ11B (‰) and (c,d) boron to calcium ratios (B/Ca) for all four colonies sampled of Acropora yongei and Pocillopora damicornis. Coloured symbols represent each colony while the black symbols with lines denote the mean ± 1 SE (n = 4) for each time point. Light blue shading denotes winter and unshaded areas denote summer, defined based on seasonal changes in temperature and light.
