| Zusammenfassung |
| Distinct mid-glacial δ18O enrichment events found at Site U1386 in the Gulf of Cadiz during Marine Isotope Stages 6 and 8 represent a striking feature absent in most deep-sea benthic δ18O records studied worldwide. These δ18O enrichment events are closely related to periods of maximum precession and aligned with previous findings from the Mediterranean and Red Seas. Here we present paired planktic and benthic stable isotope (δ18O and δ13C) and Mg/Ca-based temperature records of Site U1386 of the last 300.000 years. Our results show that these δ18O enrichment events are recorded in both subsurface and bottom water masses and pre-date the largest cooling events along the Iberian Margin and associated European sourced meltwater pulses of the Drenthe and Fuhne major ice-sheet advances, suggesting that they instead correspond to periods of maximum ice volume extend in Europe. |
