After years of negotiation with hundreds of governments and institutions, the first map showing the entire range of magnetic anomalies on Earth has finally been released.

More than 50 years of data gathered by aeromagnetic surveys, research vessels, and orbiting satellites by various agencies around the globe have been compiled onto one map that is available through the Commission of the Geological Map of the World.

You can read more about it at the BBC website as well as download a low-rez version of the map as a pdf file here.
