Figure F7. Magnetic anomaly pattern and paleopole positions for the 168.6°W seamount. A. Magnetic anomaly pattern (red/blue scale) and topography (black lines = 500 m contours). Survey track shown as dashed green line. B. Paleopole positions (and 95% confidence bounds in red) derived from the uniform magnetization component for misfits of 60–20 nT with a seminorm inversion compared to Pacific poles from Sager and Pringle (1987) (black). LSQ = least-squares solution. Note that the anomaly pattern is of quite low amplitude and relatively complex, possibly suggesting the presence of dual polarities (reversed polarity dominant).
