Description

We present a high-resolution paleotemperature reconstruction from a marine sediment core (GP04PC) recovered in the westernmost Mediterranean, the Alboran Sea basin, over the last 35 kyr using for the first time in pararell four independent organic sea surface temperature (SST) proxies (UK'37, TEXH86,RI-OH' and LDI). We also present the δ18O of planktonic foraminifera G. bulloides record together with records of bulk parameters (total organic carbon content, δ13Corg) and the accumulation rates of different biomarkers, providing insights in terrestrial input and primary productivity variations. 

We have also examined the Bayesian calibrations BAYSPLINE for UK'37 and BAYSPAR for TEX86, although the non-Bayesian calibrations are used in this study.
