Subdecadal Holocene climate reconstruction of Byers Peninsula (Antarctica).
Byers Peninsula (Livingston Island, South Shetland Islands) is one of the few glacier-free areas in Antarctica that allow the high-resolution characterization of Holocene history based on paleolimnological studies. Several lakes on the peninsula with sedimentary infills up to 5 m of thickness provid...
