RIMS Lab/Scanning Lab
The research focuses on understanding and using coral geochemistry to reconstruct ocean-atmosphere interactions. The group uses paleoclimate proxies in the coral skeleton (e.g., stable isotopes) to reconstruct the climate of the last 500 years and utilizes coral skeletons as recorders of environmental conditions, providing insights into climate behavior.
