Multi-proxy analysis of sediment cores from Lake Azul (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 Azul located in São Miguel island has a surface area of 4.35 km, 28m of maximum depth and is located at 259m above sea level. A coring campaign was conducted in September 2011 using a 60mm diameter UWITEC gravity corer from UWITEC floating platform retrieving a Core AZ11_02 (1.70 m long) located in the deep basin of the lake (27m depth). 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 660 years.
