Ice age effects on the satellite-derived J˙2 datum: Mapping the sensitivity to 3D variations in mantle viscosity

Autor: Kim, AJ, Crawford, O, Al-Attar, D, Lau, HCP, Mitrovica, JX, Latychev, K

Studies of glacial isostatic adjustment (GIA) based on spherically symmetric viscoelastic Earth models have argued that the rate of change of the degree 2 zonal harmonic of the Earth’s geopotential, or J˙2, provides an important constraint on mean

Constraining Jumps in Density and Elastic Properties at the 660 km Discontinuity Using Normal Mode Data via the Backus-Gilbert Method

Autor: Lau, HCP, Romanowicz, B

Publikováno v: Geophysical Research Letters, vol 48, iss 9

We apply the Backus-Gilbert approach to normal mode center frequency data, to constrain jumps in P, S, bulk-sound speed and density at the “660” discontinuity in the earth’s mantle (∼650–670km depth). Different 1-D models are considered to

Thermally dominated deep mantle LLSVPs: A review

Autor: Davies, DR, Goes, S, Lau, HCP

The two large low shear-wave velocity provinces (LLSVPs) that dominate lower-mantle structure may hold key information on Earth’s thermal and chemical evolution. It is generally accepted that these provinces are hotter than background mantle and ar
