230Th, 231Pa, excess sedimentary ratio decay corrected from deposition time (Pa/Th) and 230Th-normalized flux data for the new cores. 
Table A- SU90-44, 
Table B- MD95-2027 (the bolded and italic lines are the data with error bar larger 
than 0.008 (2 sigma) , not taken into account in the mean calculation, and in light grey 
in the figures), 
Table C- MD95-2037

3.2008PA001696-fs03.eps
Comparison of sedimentary Pa/Th signal from core MD95-2037 (A-) with Fe/232Th (B-) and Mn/232Th (C-). The relative fluxes of Fe and Mn normalized to 232Th are compared with their respective pelagic clay (P. C.) and continental crust (C. C.) ratios as reference.
