“…For example, there have been numerous inferences of Tharsis-driven TPW based on tectonic patterns, geomorphologic features, magnetic anomalies and grazing impacts (see introduction and also Sprenke et al, 2005). In addition, there have been theoretical predictions of polar wander driven by a surface mass loading consistent with the size and current location of Tharsis (Melosh, 1980;Willemann, 1984;Matsuyama et al, 2006Matsuyama et al, , 2007.…”

“…tian rotation vector. First, to what extent did the development of Tharsis, which is now located near the equator of the planet (Zuber and Smith, 1997), cause TPW (Melosh, 1980;Sprenke et al, 2005)? Second, how stable is the current rotation axis to changes in the surface and internal mass distribution (Bills and James, 1999)?…”

“…[Note that the Gold (1955) scenario includes a physical inconsistency since it assumes that the rotational bulge will relax perfectly to a change in centrifugal potential but that the surface load is never completely compensated isostatically.] It remains a common view, following Gold's influential analysis, that the stability of the martian rotation pole-both at present day and in response to Tharsis loading-is governed by the observed figure of the planet after correction for a hydrostatic form (Melosh, 1980;Bills and James, 1999;Sprenke et al, 2005).…”

“…That is, relatively small surface mass loads can cause large (order 90 • ) excursions of the pole along the great circle joining the present-day pole and the maximum non-hydrostatic inertia axis. Furthermore, analysis of the non-hydrostatic form, after correction for the signal from Tharsis loading, has led to a conclusion that the development of this volcanic province must have induced a large (15 • -90 • ) excursion of the rotation pole (Sprenke et al, 2005).…”

“…Willemann (1984) recognized that the presence of an elastic shell has a potentially significant stabilizing effect on TPW. However, his analysis, recently refined and corrected by Matsuyama et al (2006), has been neglected in subsequent studies of Mars' rotational stability (Bills and James, 1999;Sprenke et al, 2005). There may be two reasons for this neglect.…”
