Tomographic filtering of high‐resolution mantle circulation models: Can seismic heterogeneity be explained by temperature alone? (2009, methodology): “…1977; Su et al., 1994; Li and Romanowicz, 1996;Grandetal., 1997;vanderHilst et al., 1997;Su and Dziewonski, 1997;Kennett et al., 1998;Masters et al., 2000; Ritsema et al., 2004; Montelli et al., 2006; Panning and Romanowicz, 2006; Simmons et al., 2007; Houser et al., 2008; Kustowski et al., 2008].”
Constraints on lithosphere net rotation and asthenospheric viscosity from global mantle flow models and seismic anisotropy (2010, methodology): “We assign densities in the mantle by converting velocity anomalies in the S20RTSb seismic tomography model [Ritsema et al., 2004] to densities using a constant velocity‐density conversion factor of 0.”
Global mantle flow and the development of seismic anisotropy: Differences between the oceanic and continental upper mantle (2007, methodology): “For density-driven flow, we employ rigid surface boundary conditions and assign densities in the mantle by converting velocity anomalies in the S20RTSb seismic tomography model [Ritsema et al., 2004] to densities using a constant velocity-density conversion factor of 0.”
Importance of crustal corrections in the development of a new global model of radial anisotropy (2010, background): “details in structure of isotropic S velocity [Mégnin and Romanowicz, 2000; Gu et al., 2003; Ritsema et al., 2004; Montelli et al., 2006; Houser et al., 2008; Simmons et al., 2009] as well as P velocity [Montelli et al.”
Anisotropic shear‐wave velocity structure of the Earth's mantle: A global model (2008, unknown): “Some recent models [Mégnin and Romanowicz, 2000; Gu et al., 2001a] show the continental signatures extending below 300 km, while in others [Masters et al., 2000; Ritsema et al., 2004] strong continent– ocean differences are confined to the uppermost 200 km of the mantle.”
Inferring upper-mantle structure by full waveform tomography with the spectral element method (2011, background): “The inclusion of overtones is crucial for resolving structure deeper than about 300 km, including the transition zone (e.g. Ritsema et al. 2004).”
A simple method for determining the spatial resolution of a general inverse problem (2012, background): “The kernels have a finite spatial extent (Ritsema et al. 2004) corresponding to the resolution length.”
Thermal versus elastic heterogeneity in high‐resolution mantle circulation models with pyrolite composition: High plume excess temperatures in the lowermost mantle (2009, methodology): “Models S20RTS and TX2007 have much smaller amplitudes in almost all depth levels compared to models HMSL-S06 and PRI-S05 which may reflect differences in tomographic resolution due to different inversion procedures or data sets used.”
Integrated geophysical‐petrological modeling of the lithosphere and sublithospheric upper mantle: Methodology and applications (2008, background): “…of Archean cratons are as follows: (1) fast seismic anomalies in the upper 250–350 km depth range [Ritsema and van Heijst, 2000; Gung et al., 2003; Ritsema et al., 2004], (2) highly depleted compositions [Boyd, 1989; Boyd et al., 1997; O’Reilly et al., 2001; Griffin and O’Reilly, 2007], and (3)…”
Age, spreading rates, and spreading asymmetry of the world's ocean crust (2008, methodology): “[30] We have labeled the areas outlined above in Figure 11a, and assembled a set of maps of past subduction zone locations paired with seismic tomography cross sections from Ritsema and van Heijst [2000] and Ritsema et al. [2004] (Figure 12).”
A global study of transition zone thickness using receiver functions (2006, background): “The transition zone thickness is sensitive to velocity heterogeneity within the transition zone [e.g., Ritsema et al., 2004 ].”
Gravity anomalies, flexure and the elastic thickness structure of the India–Eurasia collisional system (2005, background): “Seismic tomographic data shows that the mantle below parts of the continents has a significantly higher shear wave velocity at 120 km depth than has the oceans [60].”
Dynamics and evolution of the deep mantle resulting from thermal, chemical, phase and melting effects (2012, background): “model S20RTS (Ritsema et al., 1999; Ritsema et al., 2004) with (B) thermo-chemical”
Global upper-mantle tomography with the automated multimode inversion of surface and S-wave forms (2006, methodology): “Multimode waveform techniques (Cara & Lévêque 1987; Nolet 1990; Gee & Jordan 1992) can constrain both the structure in the upper 200–300 km of the mantle—sampled primarily by the fundamental mode surface waves—and the structure below, down to the transition-zone—sampled by S and multiple S waves (”
On the robustness of predictions of sea level fingerprints (2011, background): “…was highlighted by Vellinga et al. (2008), who in a study of the hazard posed by sea level change in the Netherlands, wrote: ‘At present, the causes for the large differences in fingerprints presented by Mitrovica et al. (2001) . . . and Plag and Jüttner (2001) . . . are not fully explained. . .”
An anisotropic shear velocity model of the Earth's mantle using normal modes, body waves, surface waves and long-period waveforms (2014, background): “Several earlier studies have used diverse types of data for inversions of mantle heterogeneity (e.g. Dziewoński & Woodward 1992; Masters et al. 2000a; Gu et al. 2001; Ritsema et al. 2004).”
