Coral, climate memory

By 29 juillet 2020 No Comments

Analysis performed on coral samples collected during the Tara Pacific expedition, organized by the Tara Ocean Foundation in partnership with the Centre scientifique de Monaco (CSM) and the CNRS, provided first results on paleoclimatology. Recent discoveries based on samples of coral skeletons have enabled scientists to reconstruct changes in sea surface temperature over time.

During this mission, scientifically coordinated by the CSM and CNRS, extensive coral sampling was carried out as the schooner Tara crossed the Pacific Ocean from east to west and from south to north. 40% of the world’s coral reefs are concentrated in this region. After 2 and a half years of sailing, the 35,000 samples collected are now being carefully analyzed.
