EarthRef.org Digital Archive (ERDA) -- Magnetic Profiles Along Three Different Mid-Ocean Ridges

Description
Computed magnetic field anomalies over oceanic crust for different mid-ocean ridges on earth. The magnetic anomalies (stripes) differ for mid-ocean ridges at different latitudes and different azimuths relative to the dipole magnetic field lines. In the northern hemisphere normally magnetized oceanic crust will show enhanced magnetic anomalies (e.g. Pacific and Atlantic examples) while southern hemisphere ridges show the opposite (Carlsberg ridge). For more detail see Vine and Matthews (1963).

Instructions
The Earth's magnetic field strength varies depending on the the location on the globe. How is this illustrated in the three graphs of the Earth's magnetic field at different locations?
