Here we present a multi-proxy record from palaeolake Fucino (Abruzzo, Central Italy), acquired during the F1-F3 drilling campaign. This is the first continuous and high-resolution palaeoenvironmental record in the central Mediterranean region continuously spanning over the last two glacial-interglacial cycles and providing an independent chronology.The record consists of a core composite resulting from two parallel and adjacent core series (F1 and F3). Cores were analysed via high resolution XRF scanning and through geochemical, mineralogical and grain-size analyses on discrete samples. Selected XRF elemental counts (Ca, Ti and Zr), Total Nitrogen (TN), Total Organic and Inorganic Carbon (TOC, TIC), X-ray powder diffraction and grain-size data are used to develop proxies for local environmental processes strictly dependent on the hydro-climatic regime of the Central Mediterranean region.The chronology of the record is based on 17 radioisotopically dated tephra layers interbedded within the sedimentary succession. 14C and 40Ar/39Ar age points are interpolated with the bayesian age modelling package Bacon allowing a robust assessment of age uncertainties.
