Summary

The dominant geologic process on planet Earth is creation of new oceanic crust, which hosts life and holds the history of Earth origin and evolution. The Moho is a seismic boundary assumed to represent the frontier between the crust and the mantle. We have not yet crossed this frontier, and the mission is primarily to determine the nature of the Moho. To drill and sample through crust into the mantle, is to understand the process of planetary renewal and how the surface of Earth is paved. The journey across this frontier and beyond into the Earth’s mantle, the driver of plate tectonics, will take us through the primal architecture of this planet.

Mission Moho will build upon and utilize new technologies to achieve the long-term (40 yr) goal of drilling to the mantle, which was the inspiration for scientific ocean drilling. The ability to conduct this mission through the IODP international partnership will create a legacy for generations to come.
