Comment:

Position of the seamounts, except DSDP samples, are estimated. All uncertainties are given at 95% confidence level. Ages were calculated using an age of 28.02 Ma for Fish Canyon sanidine (Renne et al., 1998, doi:10.1016/S0009-2541(97)00159-9), and decay constants and isotopic abundances of (Steiger and Jager, 1977, doi:10.1016/0012-821X(77)90060-7).
