Abstract:

The SST records of core DCR-1PC (Crosta et al., 2020) and the subST records of cores MD19-3575CQ (this study) were resampled at a 3kyrs interval to substract subST to SST. This allowed to reconstruct the evolution of the delta of temperature (deltaT) between surface and subsurface. We here include the resampled and deltaT records.
