Multi-proxy analysis of sediment cores from Lake Caldeirão (Azores archipelago, Portugal)
The Azores archipelago is a group of nine oceanic volcanic islands located in the mid-North Atlantic, roughly 1500 km from Europe and 1900 km from America. Lake Caldeirão is situated in the central caldeira of Corvo Island at 399 m altitude. A coring campaign was conducted in June 2017 using a 60mm...
