Thomas received his PhD from Woods Hole Oceanographic Institution in 2017. Since joining the ARC COE for Coral Reef Studies at UWA, his research has focused on understanding mechanisms of the sensitivity, and resilience, of coral calcification to ocean acidification and warming. Thomas is employing novel techniques based on the Raman scattering of lasers focused onto coral skeletons to quantify the chemical conditions under which the skeleton was accreted. Analyses of both laboratory-cultured and wild corals are providing insight into the relationships between seawater conditions (including pH and temperature) and the corals’ calcifying internal fluid that dictates the rate of skeletal growth. This information is critical for understanding how coral calcification is responding to the rapidly changing temperature and chemistry of our oceans.
