Stylasterids are a ubiquitous deep-sea coral taxon that build their skeletons from either calcite, aragonite, or both. Yet, robust geochemical proxy data from these corals are limited. In this study, 95 modern stylasterids, spanning a wide range of depths (63 to 2894 m) and ambient seawater temperatures (0 to 17° C), were tested for their potential use as paleoceanographic archives. Stable oxygen and carbon isotopic composition (δ 18 O and δ 13 C) were measured from the main trunk of all specimens and five specimens were further sub-sampled to assess internal chemical variability. The isotope data show non-equilibrium precipitation from seawater for both δ 18 O and δ 13 C, with the growing tips of colonies yielding the isotopically lowest values. Overall, the calcitic corals showed lower isotope values for δ 18 O and δ 13 C than aragonitic specimens. Within the aragonite corals, we present a δ 18 O: temperature calibration that exhibits a significant linear relationship with the equation δ 18 O coral-seawater=− 0.22 (±0.01)× T (° C)+ 3.33 (±0.06) across a temperature range of 0 to 30° C, using samples from this study and published data. This work highlights the potential application of stylasterid coral δ 18 O data to reconstruct paleo seawater temperature.
