Figure 5

Magnetic anomaly maps of Norton Sound before and after leveling correction. Prominent false-lineated anomalies along the track lines in the map before correction (A) almost disappear after leveling correction using a filtering width of 3 h and a weight distance of 2 km (B). Contours are at 20 nT intervals; thicker contours are at 100 nT intervals.
