Description
The westernmost Mediterranean is one of the most sensitive areas to global climate change and high sedimentation rates allow recording high frequency variability. We present a high‐resolution paleotemperature reconstruction over the last 35 kyr using, for the first time, four independent organic sea surface temperature (SST) proxies (UK'37, TEXH86, RI‐OH' and LDI) based on alkenones, (hydroxy) isoprenoid GDGTs, and long‐chain diols. We also generated a 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 to provide insights into terrestrial input and primary producers. All derived‐SST records showed similar trends over the last 35 kyr, revealing abrupt temperature variations during the last seven Dansgaard‐Oeschger (D/O) cycles, the three Heinrich (H) events, the Last Glacial …
