Illustration of a Geomagnetic-Polarity Timescale
This image displays geomagnetic-polarity epochs and their correlation to an age in millions of years and a specific magnetic anomaly. The age of the seafloor is based on K-Ar dating. Blue anomalies represent normal magnetic polarities and red anomalies are reversed magnetic polarities.

Magnetic Anomaly Data for Multiple Seafloor Locations
Each section of seafloor has two graphs representing the two magnetic profiles taken at the same location. The data from the two profiles at each location is combined in the third graph to filter out variances in the measurement of the magnetic field. Measurements below the axis represent ...
