Antipodal Seismic Observation and Sensitivity Kernel for the Liquid Region on the Earth’s Inner Core

Geosciences
It is considered that a part of the inner core surface where iron in the fluid outer core is precipitated may have melted and formed a mushy region, but its position is not well understood seismologically.

Hydrogen and silicon are the preferred light elements in Earth’s core

Communications Earth & Environment
Hydrogen is an important light element in the Earth’s core for its high cosmochemical abundance and strong affinity to iron under core-formation conditions.

The role of the equivalent blackbody temperature in the study of Atlantic Ocean tropical cyclones [PDF]

Satellite measured equivalent blackbody temperatures of Atlantic Ocean tropical cyclones are used to investigate their role in describing the convection and cloud patterns of the storms and in predicting wind intensity.

The Earth's Inner Core

, 2017
The inner core is a planet within a planet: a hot sphere with a mass of one hundred quintillion tons of iron and nickel that lies more than 5000 kilometres beneath our feet. It plays a crucial role in driving outer core fluid motion and the geodynamo, which generates the Earth's magnetic field.

Oxygen Driving Hydrogen Into the Inner Core: Implications for the Earth's Core Composition

Geophysical Research Letters
Earth's core should contain light elements to account for the density deficit relative to pure iron as inferred from seismic observations. Of particular interest is hydrogen, as planetary accretion models predict the delivery of water possibly ...

A New Global Theory of the Earth's Dynamics : a Single Cause Can Explain All the Geophysical and Geological Phenomena

, 2005
After describing all the contradictions associated with the current Plate Tectonics theory, this paper proposes a model where a single cause can explain all geophysical and geological phenomena.

Viscosity of Iron-Sulfur Alloy under the Conditions of the Earth Inner Core Calculated Based on the Neural Network Potential

Gaoya wuli xuebao
The density of the Earth’s inner core is lower than that of pure iron, indicating the presence of light elements. Among the candidate elements, carbon, hydrogen, oxygen, sulfur, and silicon are considered the most likely.

Heterogeneity and Anisotropy of Earth's Inner Core

Annual Review of Earth and Planetary Sciences, 2014
Seismic observations provide strong evidence that Earth's inner core is anisotropic, with larger velocity in the polar than in the equatorial direction. The top 60–80 km of the inner core is isotropic; evidence for an innermost inner core is less compelling.
