Abstract:
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 Peixinho located in Pico island 14m of maximum depth and is located at 874m above sea level. A coring campaign was conducted in June 2015 using a 60mm diameter UWITEC gravity corer from UWITEC floating platform retrieving a core (2.53 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 1500 years.
