age_depth_bath_${age}.xyadb             A simple ASCII file (long, lat, age, depth-to-basement, bathymetry).
                                        The age units are in millions of years with no scaling.
					The depth-to-basement and bathymetry are in meters with no scaling.
                                        The file spans longitudes from 0 E to
                                        360 E and latitudes from 90 N to -90 N.
                                        6 minute resolution, gridline-registered.

Improvements:		We have included a model for the oceanic crust in the Bering Sea after the
			Science paper submission.
						An interpolation artifact off the east coast of India
						has been fixed (18 July, 2008)
                                        
Known Bugs:             Gridding artifacts exist around microplates (e.g.
Bauer microplate), along fracture zones (e.g. Central Atlantic) and in
areas with highly oblique spreading (e.g. South-West Indian Ridge).
