Inferring upper-mantle structure by full waveform tomography with the spectral element method (2011, background): “This may be a plausible explanation, since mantle wedges have high water content (e.g. Hirschmann 2006) favouring B- and C-type fabric formation (Katayama & Karato 2006).”
Accretion and differentiation of the terrestrial planets with implications for the compositions of early-formed Solar System bodies and accretion of water (2014, background): “…parameter in least squares regressions but is simply adjusted to obtain approximately 1000 ppm H2O in the Earth’s primitive mantle at the end of accretion (O’Neill and Palme, 1998; Palme and O’Neill, 2013), although this concentration might be a slight overestimate (Hirschmann, 2006, pers. comm.).”
The solid Earth’s influence on sea level (2013, methodology): “Much of Earth’s water may be currently stored in hydrated minerals within Earth’s mantle (Hirschmann, 2006; Ohtani, 2005; Williams and Hemley, 2001), particularly within the transition zone (Inoue et al., 2010; Karato, 2011).”
Heterogeneous accretion, composition and core–mantle differentiation of the Earth (2011, methodology): “Two-dimensional simulations of the settling of metal droplets in a magma ocean support this polybaric equilibration model (Höink et al., 2006).”
Complex subduction and small-scale convection revealed by body-wave tomography of the western United States upper mantle (2010, background): “Decompression melting beginning at 90–125 km depth is consistent with hydrated peridotite (300–1000 ppm H2O) ascending along a ridge adiabat (Hirschmann, 2006), and hydration of the western U.”
WATER LOSS FROM TERRESTRIAL PLANETS WITH CO2-RICH ATMOSPHERES (2013, unknown): “Water is important on Earth most obviously because it is essential to all life, but major uncertainties remain regarding how it was delivered, how it is partitioned between the surface and mantle, and how much has escaped to space over time (Kasting & Pollack 1983; Hirschmann2006; Pope et al. 2012).”
On the origin of the asthenosphere (2012, background): “Hirschmann (2006) estimated this to be ~0.4%, but later Hirschmann et al. (2009) corrected this to ~0.05%).”
Water and astrobiology (2007, background): “Current estimates range from 0.1 to 1.5 additional hydrospheres in the mantle and up to 100 in the core, although actual amounts in the core could be much smaller than this, even zero (Williams and Hemley, 2001; Hirschmann, 2006).”
Intercalibration of FTIR and SIMS for hydrogen measurements in glasses and nominally anhydrous minerals (2007, background): “Hydrogen also has a signiÞ cant inß uence on the location and extent of partial melting (Asimow et al. 2004; Hirschmann 2006; Hirth and Kohlstedt 1996).”
A review of water contents of nominally anhydrous natural minerals in the mantles of Earth, Mars and the Moon (2010, background): “Although reviews ofwater inminerals (Beran and Libowitzky, 2006; Ingrin and Skogby, 2000; Johnson, 2006; Skogby, 2006) andwater in the mantle (Bolfan-Casanova, 2005; Hirschmann, 2006; Hirschmann et al., 2005; Ohtani, 2005) have been published recently, the present one”
Geodynamic Significance of Seismic Anisotropy of the Upper Mantle: New Insights from Laboratory Studies (2008, unknown): “A-type Parallel to flow Small splitting B-type Normal to flow Parallel to the plane C-type Parallel to flow Normal to the plane D-type Parallel to flow Small splitting E-type Parallel to flow Small splitting VSH/VSV anisotropy Fabric Horizontal flow Vertical cylindrical flow A-type VSH/VSV > 1 VSH/V”
Water distribution across the mantle transition zone and its implications for global material circulation (2011, unknown): “Therefore current electrical conductivity observations do not rule out a model of the lower mantle water content similar to that of the uppermantle (Hirschmann, 2006; Rüpke et al., 2006).”
