A sequence of time-dependent global raster images (JPEG images,
generated from GMT grid files of dynamic topography). The dynamic
topography comes from the work of Bernhard Steinberger at NGU.  The raster
images were created by Robin Watson at NGU.

The dynamic topography model is based on:
Muller, R. D., Sdrolias, M., Gaina, C., Steinberger, B. \& Heine, C.,
2008. Long-term sea level fluctuations driven by ocean basin volume
change, Science, 319, 1357--1362, doi:10.1126/science.1151540.

The seismic topography model on which it based is from:
Ritsema, J. & van Heijst, H.J., 2000. Seismic imaging of structural
heterogeneity in Earth's mantle: Evidence for large-scale mantle flow,
Sci. Progr., 83, 243--259.
