Topography and Predicted Bathymetry of the World with Present-day Plate Boundaries, 1999. Plate boundaries are from the PLATES Project digital data compilation. Topography/predicted bathymetry data are from Smith, W. and Sandwell, D. (Science, vol. 277, pp. 1956-1962) plotted using the GMT mapping software (Wessel and Smith, 1991, EOS, Transactions AGU, vol. 72, pp. 441, 445-444).
