| Summary: | Here, we present high-resolution planktic foraminiferal proxies combined with ANN based-SST and IRD records from IODP Site U1385 (), SW Iberian Margin for the intervals representing MIS 8 deglaciation, MIS 7 interglacial complex and MIS 6 glacial inception. The long-term SST pattern is modulated by insolation and precession parameters across the MIS 7 interglacial complex and is superimposed by the millennial-scale variability (stadials at ~250, ~243, ~230, ~221, ~203, ~196 and ~192 ka). The regional SST records indicate high temperature gradient (~6 °C) between the sub-polar North Atlantic Ocean and the SW Iberian Margin during MIS 7d which enhanced the moisture transport from mid-to-high latitudes. Further, low obliquity with low insolation induced cooling at high latitudes and promoted the expansion of ice-sheets during MIS 7d. Comparison of our faunal proxies with the published marine and terrestrial records from SW Europe and western Mediterranean Sea suggested a weakening and southward shift of Azores ... |
