The present best estimates of seismic velocities in the core are compared with the 1939 solution of Jeffreys, with emphasis on the remaining uncertainties and present resolution capability. The relative contributions of measurements of seismic body waves and terrestrial eigenspectra to the inverse problem of the determination of elastic parameters, density and damping in the core are compared. Linear perturbation algorithms and smoothing functions used with the spectral data reduce their… Expand
Summary of seismological constraints on the structure of the Earth's core
We review the current state of the seismological constraints on core structure. The evidence supports a simple two-layer model of the core. The fluid outer core seems to have properties which areExpand
Q in the inner core
Short-period vertical seismograms from ten earthquakes and one nuclear explosion in the distance range of 140-170 degrees are examined for a study of the anelastic properties of the inner core. TheExpand
Deep earth structure
Major developments in earth structure in the last four years have been concentrated in the description of the earth's lateral heterogeneity: the regions that are heterogenous and the per centExpand
50 years of studies on the inner core
In 1986, we marked the 50th anniversary of the discovery of the earth's innercore. In atomic physics an equivalent act would warrant a Nobel prize. The credit is due to Inge Lehmann (Figure 1), whoExpand
Magnetic Rossby waves in a stably stratified layer near the surface of the Earth's outer core
Abstract The stratification profile of the Earth's magnetofluid outer core is unknown, but there have been suggestions that its upper part may be stably stratified. Braginsky (1984) suggested thatExpand
Structure of the Core and Lower Mantle
Publisher Summary This chapter analyzes the structure of the core and lower mantle of the Earth. It reviews the recent progress in the construction of such models of the Earth's deep interior,Expand
Compositional Convection and the Earth’S Core
The Earth is cooling and the solid inner core is growing as the outer core freezes. The outer core is composed primarily of iron but it contains a small fraction of some lighter constituent. FreezingExpand
A FORTRAN 77 program to compute seismic rays traveling inside a radially inhomogeneous Earth
Abstract This is a simple, general purpose computer program written in FORTRAN 77 for seismic ray tracing inside a radially inhomogeneous Earth. The program is documented and tested. The ray-shootingExpand

TLDR
This dissertation advocate the use of Bayes factors in empirical research to replace or complement standard null hypothesis tests based on p-values, and implemented them in Jeffreys’s Amazing Statistics Program, JASP, which is freely available and open-source. Expand
Harold Jeffreys’s default Bayes factor hypothesis tests: Explanation, extension, and application in psychology
Abstract Harold Jeffreys pioneered the development of default Bayes factor hypothesis tests for standard statistical problems. Using Jeffreys’s Bayes factor hypothesis tests, researchers can gradeExpand
