Figure 3 : Offset of A. islandica data from
temperature regressions . Shaded grey points show residual
∆47 values relative to four clumped isotope temperature
relationships (see horizontal axis). Black symbols with error bars (95%
CL) show mean offsets of all A. islandica datapoints (grown at
1°C, 3°C, 6°C, 15°C and 18°C) from the calibrations. The vertical axis
on the right shows the temperature offset relative to the weighted mean
calcification temperature of the full A. islandica dataset
(8.6°C; see S4 ) based on Anderson et al. (2021).
