Notes: Mean paleomagnetic directions and statistics calculated using Fisher statistics for each core. We used data from stable polarity intervals. Reversed polarity intervals were inverted prior to computing mean directions and statistics. Inclination = mean paleomagnetic inclination from stable polarity intervals in core, declination = mean paleomagnetic declination from stable polarity intervals in core. By subtracting this value from observed paleomagnetic declinations measured along core, core can be approximately reoriented back into geographic coordinates. After reorientation, normal polarity intervals will have ~0° declination and reversed polarity intervals will have ~180° declination. N = number of paleomagnetic observations used in calculating mean, R = resultant vector length from summing N vectors (directions or poles), k = precision parameter from Fisher statistical calculations, α95 = 95% confidence angle for mean direction.
