The sediment core KES2 (37.94558° N, 22.57641° E) was retrieved from the Kaisari Polje, Peloponnese Greece, in spring 2017 using a piston corer (Stitz type). The sedimentary sequence covers 350 cm (sedimentary units 1 - 7). The core was scanned at 0.5 cm resolution with an Avaatech X-ray Fluorescence (XRF) core scanner and the raw data presented here is displayed as element counts per second (cps). The core sequence covers the last 6000 years and was analysed to reconstruct ecosystem and landscape changes as well as palaeoclimatic fluctuations in southern Greece.
