Lost millennium of Galapagos deep-sea corals linked to major Pacific climate shift
University of Bristol
Published: 21 April 2026
Researchers analyzed 900+ fossil corals to reconstruct 117,000 years of deep-sea coral history in the Galapagos, finding corals vanished for over 1,000 years during a prolonged La Nina phase that reduced deep-ocean oxygen levels.
