Paleomagnetic inclinations are first converted to paleocolatitudes and averaged to produce a mean colatitude. Paleocolatitude correction to remove bias, using a model for geomagnetic secular variation based on the latitude dependence of secular variation during the past 5 million years. Applied to inclination-only paleomagnetic data from Suiko Seamount, the most complete data set from a drilling site. The method is then applied to paleomagnetic data from all Deep Sea Drilling Project sites for the Pacific Plate to obtain for each site an unbiased mean paleocolatitude and its confidence limits. These paleocolatitudes and confidence limits are then used as input for a least squares analysis to obtain Early and Late Cretaceous poles for the Pacific Plate and 95% confidence limits for these poles. It is shown that the scatter of individual site paleocolatitudes about the best fit pole is consistent with the confidence limits at each site as determined by this new method of analysis.--Modified journal abstract.
