Underwater Time Machines
Coral reefs are majestic underwater metropoles providing home and refuge for countless marine species. They are amongst the most biodiverse ecosystems in the world. They also provide a window to the reef’s history. Massive stony corals like Porites can be hundreds of years old. Geochemical analyses on the annually banded cores from these underwater mounts give us information on past climatic and environmental conditions in the reefs. Working with these coral archives lets you dive into this stunning wonderland and sometimes even “Nemo” himself is welcoming you into his home.
