Thermal and magnetic evolution of the Earth’s core (2003, background): “The poorly constrained heat of reaction has not been included here and it can be argued to play a rather minor role(Gubbins et al., 2003b; Lister, 2003).”
Thermal and electrical conductivity of solid iron and iron-silicon mixtures at Earth's core conditions (2013, methodology): “To get qs = qa requires that dTo/dt ≈ 540 K Gyr−1, equivalent to a CMB heat-flux Q = 66 TW using the core energetics model in Pozzo et al. (2012) (see Gubbins et al., 2003, 2004 for a complete description).”
Scaling properties of convection-driven dynamos in rotating spherical shells and application to planetary magnetic fields (2006, background): “(46) ρ ic is the compositional contribution to the density contrast at the inner core boundary, which is estimated to be in the range 350–700 kg m−3 (Gubbins et al. 2004).”
Thermal evolution of the core with a high thermal conductivity (2014, unknown): “…a sub-isentropic CMB heat ﬂow has been mentioned for several decades (Loper, 1978; Gubbins et al., 1979; Stacey and Loper, 1984; Buﬀett et al., 1996; Gubbins et al., 2004, 1982; Labrosse et al., 1997; Lister and Buﬀett, 1998) even though the thermal conductivity was assumed much smaller than now,…”
Tomographic filtering of high‐resolution mantle circulation models: Can seismic heterogeneity be explained by temperature alone? (2009, result): “consistent with a number of studies from geodynamics, seismology and mineral physics [e.g., Glatzmaier and Roberts, 1995; Kuang and Bloxham, 1997; Boehler, 2000; Steinle-Neumann et al., 2001; Buffett, 2002; Gubbins et al., 2004; Nimmo et al., 2004; Nolet etal.,2006;Alfe `e tal.,2002,2007;vanderHils”
Sulfur's impact on core evolution and magnetic field generation on Ganymede (2005, methodology): “Motions in the liquid outer core can be generated thermally and by the inward segregation of iron from the Fe-snow and release of sulfur at the ICB.”
The paleomagnetism of single silicate crystals: Recording geomagnetic field strength during mixed polarity intervals, superchrons, and inner core growth (2006, background): “Most generally predict that the solid inner core started to grow no earlier than approx- imately 2.5–2.7 billion years ago [e.g., Labrosse et al., 2001; Labrosse, 2003; Labrosse and Macouin, 2003; Buffett, 2003], but some prefer a greater age [e.g., Gubbins et al., 2004].”
Dynamics and evolution of the deep mantle resulting from thermal, chemical, phase and melting effects (2012, background): “2002) to 8 TW (Gubbins et al., 2004).”
Reconciling dynamic and seismic models of Earth's lower mantle: The dominant role of thermal heterogeneity (2012, background): “…a CMB temperature of 40007300K (e.g. Glatzmaier and Roberts, 1995; Kuang and Bloxham, 1997; Boehler, 2000; Alf e et al., 2002; Buffett, 2002; Gubbins et al., 2004; Nimmo et al., 2004; Hernlund et al., 2005; Nolet et al., 2006; Alf e et al., 2007; van der Hilst et al., 2007; Steinberger and…”
Constraints on thermochemical convection of the mantle from plume heat flux, plume excess temperature, and upper mantle temperature (2006, background): “However, considerations of core processes led to much higher estimates of Qcmb ranging from 4 to 9 TW [Anderson, 2002], and possibly as high as 12 TW [Gubbins et al., 2004; Nimmo et al., 2004], implying much lower internal heating rate for the mantle.”
Energetics of the Core (2015, methodology): “Several simplifications may be applied to this equation (Gubbins et al. 2003,2004).”
