LINKS BETWEEN LONG‐LIVED HOT SPOTS, MANTLE PLUMES, D″, AND PLATE TECTONICS (2004, background): “…zones [e.g., Richards and Engebretsen, 1992; Grand et al., 1997; van der Hilst et al., 1997; van der Hilst and Karason, 1999; Fukao et al., 2001; Grand, 2002], lowvelocity regions correlate to the surface position of hot spots [Weinstein and Olson, 1989; Williams et al., 1998] as well as to the…”
Global upper-mantle tomography with the automated multimode inversion of surface and S-wave forms (2006, background): “They can yield more uniform resolution in the upper mantle compared both to teleseismic delay time tomography and to inversions of fundamental-mode surface-wave measurements, the former offering high upper-mantle resolution but only in regions with an abundance of seismic sources or stations (e.g. B”
TX2019slab: A New P and S Tomography Model Incorporating Subducting Slabs (2019, methodology): “The locations of these fast anomalies generally agree with previous studies (e.g., Amaru, 2007; French & Romanowicz, 2014; Grand, 2002; Li et al., 2008; Moulik & Ekström, 2014; Obayashi et al., 2013; Ritsema et al., 2011).”
The continental lithosphere: Reconciling thermal, seismic, and petrologic data (2009, methodology): “…lithospheric mantle, further analysis is based on two recent global tomography models: (i) a global surface-wave tomography model of Shapiro and Ritzwoller (2002), further referred to as RW–SR and (ii) a global teleseismic body-wave Vs tomography model of Grand (2002), further referred to as BW–G.”
Dynamics and evolution of the deep mantle resulting from thermal, chemical, phase and melting effects (2012, background): “Evidence for this is that seismic tomographic images convincingly show slabs penetrating the 660 km discontinuity, sometimes after temporarily stagnating at the base of the transition zone (Fukao, 1992; Van der Hilst et al., 1997; Grand, 2002; Zhao, 2009) and that seismically fast regions above the ”
Global transition zone tomography (2004, methodology): “The TXBW [Grand, 2002] model is entirely based on shear wave travel times.”
A new inference of mantle viscosity based upon joint inversion of convection and glacial isostatic adjustment data (2004, methodology): “Our forward predictions of these geophysical observables are based on the seismic shear wave tomography models of either Grand [54] or Ekström and Dziewonski [55].”
Morphology of seismically slow lower-mantle structures (2016, methodology): “Using the waveforms and traveltimes of a suite of shear wave phases sampling the lowermost mantle, He & Wen (2009) infer that the West Pacific anomaly reaches 740 km above the CMB and has steep sides.”
Effect of GIA models with 3D composite mantle viscosity on GRACE mass balance estimates for Antarctica (2015, methodology): “In the SEIS approach laterally varying velocity anomalies from Grand (2002) are converted to temperature using the depth-dependent temperature derivative of seismic wave velocities given in Karato (2008).”

Supercontinent cycles, true polar wander, and very long-wavelength mantle convection (2007, background): “The present-day lower mantle structure is predominated by degree-2 structures with the Africa and Pacific superplumes surrounded by subduction (Dziewonski, 1984; Masters et al., 2000; Ritsema et al., 1999; Romanowicz andGung, 2002; Van derHilst, 1997; Grand, 2002) (Fig.”
