Reaching the boundary between the Earth's crust and mantle, named for Croatian seismologist Andrija Mohorovicic, would allow scientists to peer directly into the Earth's innards, providing new insight into the planet's makeup and history and informing controversial ideas about continental drift.
One of the first results was the discovery that the ocean crust appeared to present a consistent, layered seismic structure composed of sediments (layer 1 at the seafloor) followed by two layers with rapidly increasing sound velocity, and then a reflector, dubbed the Moho after the its discoverer, a Czechoslovakian seismologist named Andrija Mohorovicic.
When Croatian seismologist Andrija Mohorovicic published his landmark discovery of a shallow transition to a remarkably uniform layer of high sound (or seismic) velocities in 1909, he had, in fact, discovered the boundary between Earth's crust and upper mantle, which is now known as the Moho.
