Mars Express has released the results of a gravity mapping program, done in conjunction with MRO, looking at volcano formation. There are two pages now on-line:

Science and Technology pages, with more slightly technical detail:

Is there a global map somewhere? It is edifying to know that there probably is, but it would be neat to see it after reading about it. Perhaps this:

Interesting that the found evidence to support a mantle plume for those three volcanoes in a line. Wonder if that means the mantle moved, but the crust didn't.

Or the other way around (or a bit of both). I recall reading some time back that the redistribution of mass associated with the bulge could have caused the surface to do a 'polar flop' and that this might account for the putative northern ocean shorelines being off-level today.
