Multi-proxy analysis of sediment cores from Lake Funda (Azores archipelago, Portugal)

DOI

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 Funda is situated in the southern sector of the central plateau of Flores Island at 351 m altitude and occupies the bottom of a small maar-explosion crater with 875 m in length and 625 m width, with a total area of 0.37 km2 where several water lines converge. A coring campaign was conducted in June 2017 using a 60mm diameter UWITEC gravity corer from UWITEC floating platform retrieving a core (9.97 m long) located in the deepest part of the lake. The core was dated using ¹⁴C and produced a multi-proxy dataset of geochemical and biological analyses that we used to uncover paleoenvironmental changes on Lake Azul in the last 1300 years.,
