Thermal versus elastic heterogeneity in high‐resolution mantle circulation models with pyrolite composition: High plume excess temperatures in the lowermost mantle (2009, background): “…our current limited understanding provides estimates ranging from 0.1 to 3.5 TW [Roberts and Glatzmaier, 2000; Buffett, 2002; Roberts et al., 2003; Labrosse, 2003; Gubbins et al., 2003; Christensen and Tilgner, 2004], The total core heat loss may thus approach 9–12 TW. Specifically, this implies…”
The intensity of the geomagnetic field in the late-Archaean: new measurements and an analysis of the updated IAGA palaeointensity database (2009, background): “P b SH R IM P zi rc on (B la ke et al ., 20 04 ). convection (Buffett, 2003; Labrosse, 2003).”
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].”
Energetics of the Core (2015, methodology): “…will be useful to expand Is as follows: Is = 4 3 πTcenρcenr 3 ce −r2c/A2 ( 1 + 2 5 r2c A2 + · · · ) (56) The temperature profile will depart from the adiabat in the inner core, but Labrosse (2003) argues that the integral may be taken over the entire core without introducing significant errors.”
Dipole moment scaling for convection-driven planetary dynamos (2005, background): “Thermal historymodels indicate that the buoyancy flux F has changed with time, due to secular cooling and inner core growth [34,35].”
Dynamo Scaling Laws and Applications to the Planets (2010, background): “The amount of ohmic dissipation in the Earth’s core has been a contentious issue, with estimates ranging between 0.1 and 3.5 TW (Buffett 2002; Roberts et al. 2003; Labrosse 2003; Gubbins et al. 2003; Christensen and Tilgner 2004).”
Modelling the palaeo-evolution of the geodynamo (2009, background): “Thus, in order to achieve scaling predictions relevant to the Precambrian Earth dynamo, one needs a time-series of the dynamo power, which can be evaluated from core thermodynamics and Earth cooling histories (e.g. Labrosse 2003; Lister 2003).”
Temperatures, Heat, and Energy in the Mantle of the Earth (2007, background): “Such a slow variation is compatible with thermal evolution models of the Earth’s core, provided that ohmic dissipation increased by a factor of four when the inner core started crystallizing (Labrosse, 2003).”
Sulfur's impact on core evolution and magnetic field generation on Ganymede (2005, background): “accurate to second-order [Labrosse, 2003].”
Thermal evolution of the core with a high thermal conductivity (2014, unknown): “This behavior was already discussed (Labrosse, 2003; Labrosse and Macouin, 2003; Aubert et al., 2009) and shows that addressing the question of the minimum value of the dissipation at the present time is not suﬃcient: because the inner core is so young, the present CMB heat ﬂow is in fact…”
