Additional Documentation: Loran data was shifted to correlate with transit satellite fixes, collected during the cruise to force the positions to near-geodetic. Some of this data was shifted again to best fit more recently collected GPS, data. Other parts of this data were cut and data from the 09880002(GPS) cruise used, to replace it in a gridded data set.
