Abstract:
This dataset accompanies a manuscript submission to Paleoceanography and Paleoclimatology, in which a new 230Th-dating method for deep-sea sediments in analogy with 210Pb-CRS dating is described. It contains all analytical data required for the dating method and the calculation of the presented fluxes, as well as the results of the dating and flux calculation. The shown uncertainties represent one standard deviation. The uncertainties of the CRS-ages have been calculated with a Monte-Carlo simulation. Methods are described in full in the accompanying manuscript.
