Magnetic Anomaly Data sets

Grids:

This data set shows two things:

• The overall difference between the spatial patterns of the magnetic anomalies on the continents and in the ocean basins.
• The general character of the marine magnetic anomalies.  Profiles from Topographic Profiles will capture the general nature of actual profiles, but will not easily allow picking the anomalies. The scale is a little too coarse.

Picks (10 Oct 2014 version)

Geology options, Magnetic anomaly picks.  This shows points where someone has identified a particular anomaly.
