A high-resolution multiproxy study of sediment core GeoB7186-3 from SE Pacific off southern South America
A high-resolution multiproxy study performed on a marine record from SE Pacific off southern South America was used to reconstruct past regional environmental changes and their relation to global climate, particularly to El Niño/Southern Oscillation (ENSO) phenomenon during the last 2200 years.
