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