We have recently begun a systematic study of surface wave dispersion across Antarctica. We include below links to graphical images of the group velocity maps. In each case, images are presented in both gif and postscript format (for down loading), and the ascii data files are also available for down loading.
These maps are still being updated, and the images and data files included here are not necessarily the most up to date. No models are available for distribution yet. To check on the status and availability of the latest maps and models, contact Mike Ritzwoller at the email address listed above.
