In this study we have applied different indices based on long chain diols, i.e., the Long chain Diol Index (LDI) as proxy for past SST, the Diol Index as indicator of past upwelling conditions and the Nutrient Diol Index (NDI) as proxy for nitrate and phosphate concentrations in seawater. The proxies were analyzed in marine sediments recovered at ODP Site 1234, located within the Peru-Chile upwelling system, with a 2 kyr resolution, covering the last 150 kyrs. We also generated TEX^H^~86 and U_K'37 temperature and planktonic δ^18^O records, as well as total organic carbon (TOC) and accumulation rates (ARs) of TOC and lipid biomarkers (i.e., C~37~ alkenones, GDGTs, dinosterol and loliolide) to reconstruct past phytoplankton production. The LDI-derived SST record co-varies with TEX^H^86- and UK'37-derived SST records as well as with the planktonic δ^18^O record, implying that the LDI reflects past SST variations at this site. TOC and phytoplankton AR records indicate increased export production during the Last ... : Supplement to: de Bar, Marijke W; Stolwijk, Dave; McManus, Jerry F; Sinninghe Damsté, Jaap S; Schouten, Stefan (2018): A Late Quaternary climate record based on long-chain diol proxies from the Chilean margin.
