Figure 2. Map showing the location and intensity of crustal magnetic sources detected by the MGS MAG/ER experiment superimposed on a topographic image of Mars (16). The measured radial (verical) component of the magnetic field associated with the crustal sources is illustrated by the color scale shown. No correction has been made for the varying spacecraft altitude, which results in attenuation of the small-scale signature of the sources with increasing altitude. The dichotomy boundary is marked by the solid line separating the northern lowlands from the southern highlands (8). Data acquired at altitudes between ~100 and 200 km for 916 elliptical orbits are included. The color scale has been chosen to illustrate the relative intensity of the crustal sources. Note the large range in magnetic field intensity associated with this color scale versus that shown in Fig. 1.
