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… 
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 are
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 cent
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), who
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 that
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. Freezing
Bayes factors for research workers

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.


The velocities in the outer core
Earlier studies of the velocity distribution in the outer core have been based on the travel times of SKS.SKS arrivals can only be observed satisfactorily for arc distances at the surface greater
