Global maps of the Mohorovičić (Moho) discontinuity across the Earth based on observations by ESA’s GOCE gravity satellite and the GEMMA project. While the Moho depth is relatively constant below sea floor, it varies by more than 70 km below continental plates. The Moho is the boundary between the Earth’s crust and its mantle. It is defined by an abrupt density variation of rock causing a change in velocity of seismic waves as they pass through the discontinuity. The Scientific colour map ‘tokyo‘ is used to represent the Moho depth data accurately and to all readers.
