ABSOLUTE GRAVIMETRY [PDF]

open access: yesGeodetski Glasnik, 2011
The paper presents problems of gravity units, the reference system for the acceleration of gravity, that is then gave a brief overview of the instruments that allow us the absolute determination of gravity, ie the determination of gravity in the full ...

Porous Au/Ti Bilayer Thin-Film Getters Based on Black Silicon for MEMS Vacuum Packaging [PDF]

open access: yesMicromachines
Porous thin-film getters are extensively utilized in the field of MEMS vacuum packaging. Nevertheless, their effectiveness is frequently constrained by the comparatively modest effective surface area of conventional planar structures.

Relativistic gravimetry

open access: yesГеофизический журнал, 2022
Work on the creation of a device that will be able to measure the parameters of the Earth’s gravitational field in space was started at the State Design Office «Yuzhnoye» in 2001 as part of the formation of a scientific research program on the «Sich-1M»

Classical and Atomic Gravimetry

open access: yesRemote Sensing
Gravity measurements have important applications in geophysics, resource exploration, geodesy, and inertial navigation. The range of classical gravimetry includes laser interferometer (LI)-based absolute gravimeters, spring relative gravimeters ...

Wind-induced seismic noise at the Princess Elisabeth Antarctica Station [PDF]

open access: yesThe Cryosphere, 2021
Icequakes are the result of processes occurring within the ice mass or between the ice and its environment. Studying icequakes provides a unique view on ice dynamics, specifically on the basal conditions.

Tunneling gravimetry [PDF]

open access: yesEPJ Quantum Technology, 2022
AbstractWe examine the prospects of utilizing matter-wave Fabry–Pérot interferometers for enhanced inertial sensing applications. Our study explores such tunneling-based sensors for the measurement of accelerations in two configurations: (a) a transmission setup, where the initial wave packet is transmitted through the cavity and (b) an out-tunneling ...

Seismic monitoring of the Auckland Volcanic Field during New Zealand's COVID-19 lockdown [PDF]

open access: yesSolid Earth, 2021
The city of Auckland, New Zealand (Tāmaki Makaurau, Aotearoa), sits on top of an active volcanic field. Seismic stations in and around the city monitor activity of the Auckland Volcanic Field (AVF) and provide data to image its subsurface.

Influence of inherited structural domains and their particular strain distributions on the Roer Valley graben evolution from inversion to extension [PDF]

open access: yesSolid Earth, 2021
The influence of strain distribution inheritance within fault systems on repeated fault reactivation is far less understood than the process of repeated fault reactivation itself.

Path and site effects deduced from merged transfrontier internet macroseismic data of two recent M4 earthquakes in northwest Europe using a grid cell approach [PDF]

open access: yesSolid Earth, 2017
The online collection of earthquake reports in Europe is strongly fragmented across numerous seismological agencies. This paper demonstrates how collecting and merging online institutional macroseismic data strongly improves the density of observations ...
