GRACE—Gravity Data for Understanding the Deep Earth’s Interior
Remote Sensing, 2020 While the main causes of the temporal gravity variations observed by the Gravity Recovery and Climate Experiment (GRACE) space mission result from water mass redistributions occurring at the surface of the Earth in response to climatic and anthropogenic ...

Outer Core Stratification From the High Latitude Structure of the Geomagnetic Field
Frontiers in Earth Science, 2018 The presence of stable stratification has broad implications for the thermal and compositional state of the outer core, the evolution of Earth's deep interior, and the energetics of the geodynamo.

Understanding the effects of the core on the nutation of the Earth
Geodesy and Geodynamics, 2017 In this review paper, we examine the changes in the Earth orientation in space and focus on the nutation (shorter-term periodic variations), which is superimposed on precession (long-term trend on a timescale of years).

From global tectonics to global geodynamics
Геофизический журнал, 2018 Observations suggest that global (plate) tectonics operates on the Earth. The most characteristic features of the global tectonics are ocean floor spreading in mid-ocean ridges and subduction in deep-sea trenches.

A coupled core-mantle evolution: review and future prospects
Progress in Earth and Planetary Science, 2020 In this review, I provide the current status and future prospects for the coupled core-mantle evolution and specifically summarize the constraints arising from geomagnetism and paleomagnetism on the long-term secular variations of the geomagnetic field ...

Interiors of Terrestrial Planets in Metric-Affine Gravity
Universe, 2021 Using a semiempirical approach, we show that modified gravity affects the internal properties of terrestrial planets, such as their physical characteristics of a core, mantle, and core–mantle boundary.

High Pressure Melting Curve of Fe Determined by Inter‐Metallic Fast Diffusion Technique
Geophysical Research Letters, 2023 The heat extracted from the core by the overlying mantle across the core‐mantle boundary controls the thermal evolution of the core. This in turn leads to the solidification of the inner core in association with the exsolution of light alloying elements ...

The Gravity Signal of Mercury's Inner Core
Earth and Space Science, 2022 In a reference frame rotating with Mercury's mantle and crust, the inner core and fluid core precess in a retrograde sense with a period of 58.646 days.

Advanced Science, EarlyView.Complex microarchitectures emerge from simple flow‐driven transformations as static mixers iteratively reorient and split material domains. Coupled with diverse deposition strategies, chaotic printing provides an accessible platform for fabricating architected materials that support biologically and chemically relevant processes. ABSTRACT Nature builds
