The velocity of the S waves in the core varies smoothly from about 3.7 km/s at the center to about 3.5 km/s at the surface. That is considerably less than the velocity of S waves in the lower crust (about 4.5 km/s) and less than half the velocity in the deep mantle, just above the outer core (about 7.3 km/s). The velocity of the P-waves in the core also varies smoothly through the inner core, from about … WebThey're counting upon international support for a $1 billion effort in which a Japanese deep-sea drilling vessel, the Chikyu, would burrow into the bottom of the Pacific Ocean to dig deeper than anyone has ever gone before.
