Fig9:

(a) overview of prism-shaped models which satisfy the sea-surface magnetic anomalies. Magnetized prisms extend 1 km in the north-south direction, 2 km in the east-west direction, and have thickness of 0.5 km.

(b) magnetized prisms are located to the north of the ship track, at around 15 km in distance in reference to the profiles of Fig. 8.

(c) comparison between the observed (plain) and calculated anomaly profiles (bold); F = total force, X = northward component, Y = eastward component, Z = downward component.
