The response of SST to insolation and ice sheet variability from MIS 3 to MIS 11 in the northwestern Mediterranean Sea (Gulf of Lions)
Here we present a sea surface temperature (SST) record based on the Uk′ 37 index from the PRGL1 borehole (Promess1) drilled on the upper slope of the Gulf of Lions (GL). This is the first continuous and high-resolution record in the northwestern Mediterranean Sea from marine oxygen isotope stage 3 (MIS) 3 to MIS 11. Due the location of the GL, the SST proxy can be considered to be a reliable tool to study the climate link between high latitude and midlatitude. During glacial inceptions, the northern ice sheet signal via cold northwesterly winds was first recorded in our study area in comparison with southern locations, highlighting the strong sensitivity of this location to high-latitude dynamics. Moreover, the amplitude of the millennial-scale variability in the western Mediterranean basin seems to be the result of both ice sheet and insolation variability. © 2015. American Geophysical Union.
