Experimental study on improving the accuracy of marine gravimetry by combining moving-base gravimeters with GNSS antenna array

期刊: EARTH PLANETS AND SPACE, 2021; 73 (1)

The gravity field is one of the Earth's basic physical fields. The geoid can be calculated and the tectonic activity underground can be inversed by gr......

Double-thin-shell approach to deriving total electron content from GNSS signals and implications for ionospheric dynamics near the magnetic equator

期刊: EARTH PLANETS AND SPACE, 2021; 73 (1)

A new technique was developed to estimate the ionospheric total electron content (TEC) from Global Navigation Satellite System (GNSS) satellite signal......

New criteria for selecting reliable Thellier-type paleointensity results from the 1960 Kilauea lava flows, Hawaii

期刊: EARTH PLANETS AND SPACE, 2021; 73 (1)

Thellier-type paleointensity experiments associated with partial thermal remanent magnetization checks have been widely used to determine paleointensi......

Separation of magnetotelluric signals based on refined composite multiscale dispersion entropy and orthogonal matching pursuit

期刊: EARTH PLANETS AND SPACE, 2021; 73 (1)

Magnetotelluric (MT) data processing can increase the reliability of measured data. Traditional MT data denoising methods are usually applied to entir......

New temperature and oxygen fugacity data of Martian nakhlite from Northwest Africa (NWA) 5790 and implications for shallow sulphur degassing

期刊: EARTH PLANETS AND SPACE, 2021; 73 (1)

Newly analysed titanomagnetite-ilmenite (Tim-Ilm) intergrowths from Martian nakhlite meteorite Northwest Africa (NWA) 5790 yielded crystallisation tem......

Semi-analytical solutions of seismo-electromagnetic signals arising from the motional induction in 3-D multi-layered media: part II-numerical investigations

期刊: EARTH PLANETS AND SPACE, 2021; 73 (1)

In this paper, numerical computations are carried out to investigate the seismo-electromagnetic signals arising from the motional induction effect due......

Various far-field hydrological responses during 2015 Gorkha earthquake at two distant wells

期刊: EARTH PLANETS AND SPACE, 2021; 73 (1)

Aquifer hydraulic parameter can change during earthquakes. Continuous monitoring of the response of water level to seismic waves or solid Earth tides ......

Analysis and prediction of polar motion using MSSA method

期刊: EARTH PLANETS AND SPACE, 2021; 73 (1)

Polar motion is the movement of the Earth's rotational axis relative to its crust, reflecting the influence of the material exchange and mass redistri......

Formation mechanisms of ringwoodite: clues from the Martian meteorite Northwest Africa 8705

期刊: EARTH PLANETS AND SPACE, 2021; 73 (1)

Ringwoodite and wadsleyite are the high-pressure polymorphs of olivine, which are common in shocked meteorites. They are the major constituent mineral......

Investigation of dominant traveling 10-day wave components using long-term MERRA-2 database

期刊: EARTH PLANETS AND SPACE, 2021; 73 (1)

The eastward- and westward-traveling 10-day waves with zonal wavenumbers up to 6 from surface to the middle mesosphere during the recent 12 years from......

Earth's free oscillations excited by the 2011 Tohoku earthquake recorded in multiple GPS networks

期刊: EARTH PLANETS AND SPACE, 2021; 73 (1)

We search in the continuous GPS 3-D displacement data for the signals of the normal modes of Earth's free oscillation that were excited by the 2011 Mw......

Estimating the lithospheric flexure of a plate with non-uniform flexural rigidity: a quantitative modelling approach

期刊: EARTH PLANETS AND SPACE, 2021; 73 (1)

Lithospheric deformation is a fundamental process in plate tectonics. It is, therefore, critical to determine how the lithosphere responds to geologic......

Global characteristics of the westward-propagating quasi-16-day wave with zonal wavenumber 1 and the connection with the 2012/2013 SSW revealed by ERA-Interim

期刊: EARTH PLANETS AND SPACE, 2021; 73 (1)

We analyze global characteristics of the westward-propagating quasi-16-day wave (Q16DW) with zonal wavenumber 1 (W1) in the troposphere and stratosphe......

Seasonal and long-term vertical land motion in Southwest China determined using GPS, GRACE, and surface loading model

期刊: EARTH PLANETS AND SPACE, 2021; 73 (1)

Owing to the intense tectonic activity and significant seasonal surface mass change, Southwest China is characterized by noticeable vertical land move......

A reduction method for magnetic disturbance caused by DC railway system

期刊: EARTH PLANETS AND SPACE, 2021; 73 (1)

The stray current of direct current (DC) railway systems causes magnetic disturbance in geomagnetic measurements, which may complicate the identificat......
