Abstract:
In this dataset we present four new high resolution ²³¹Pa/²³⁰Th records from the Blake-Bahama Outer-Ridge (ODP sites 1059-1062) covering the last 30 ka. The so formed depth-transect (3000 – 4700 m water depth) is extended by the remeasured core KNR140 12JPC (4250 m water depth). The investigated ODP sites at the BBOR have also been analyzed for major element composition of the sediment by XRF scanning of discrete bulk sediment samples and concentration measurements of biogenic opal. We also present one new ¹⁴C age for GeoB 1515-1 and recalibrated ages for this core and GeoB 1523-1 in the equatorial western Atlantic. With these new age models for GeoB 1515-1 and GeoB 1523-1, ²³¹Pa/²³⁰Th records of these cores have slightly changed in timing and amplitude.
