Whose work first showed that coral reefs can record past ocean temperatures?
Quick Answer
Geochemists and reef scientists, including Elisabeth Walliser and others, helped show that coral skeleton chemistry can preserve climate records. This made reefs valuable archives of past sea-surface temperatures.
The Full Story
Coral skeletons grow in layers and can preserve chemical clues about the water in which they formed. Researchers showed that elements and isotopes in corals can be used to reconstruct past ocean temperatures and climate conditions. This transformed coral reefs into natural climate archives, especially for studying the tropical oceans. The method is widely used today in paleoclimate research and marine science.
