| contents | High-resolution paleoproductivity variations have been reconstructed in a productive cell from core HER-GC-T1 in the Alboran Sea for the Holocene. Fossil coccolithophore assemblages have been studied along with the Uk′37-estimated sea surface temperature (SST) and oxygen isotope records. The appearance of this cell is suggested at 7.7 ka cal. BP and was linked to the establishment of the western anti-cyclonic gyre. From that time until the present, the nannofossil accumulation rate of Florisphaera profunda has revealed successive episodes of weakening and strengthening of upwelling conditions in the Alboran Sea that have been simultaneous to changes in Western Mediterranean Deep Water (WMDW) formation in the Gulf of Lions. |
