P and S velocities obtained from tau-p inversion of International Seismological Centre (ISC) travel-time data (Tralli and Johnson, 1986) are used to construct upper mantle seismic parameter profiles for oceanic regions categorized according to the square-root of crustal age and continental regions ranging from active to stable. The radial resolution of velocity anomalies is about 75 km, with a 5 by 5 degree surface tectonic regionalization. The confidence bounds on the velocities are used to place corresponding bounds on the seismic parameter, defined as the ratio of bulk modulus to density and easily determined from P and S velocities at a common depth.
