Absolute airborne gravimetry with a cold atom sensor [PDF]

open access: yesJournal of Geodesy, 2019
Measuring gravity from an aircraft is essential in geodesy, geophysics and exploration. It fills a gap between satellite techniques which have a low spatial resolution and traditional ground measurements which can only be performed on ground in ...

Characterizing Stalagmites’ Eigenfrequencies by Combining In Situ Vibration Measurements and Finite Element Modeling Based on 3D Scans

open access: yesGeosciences, 2020
Broken or deformed speleothems have been used as indicators of paleo-earthquakes since the 1990s; however, a causal link is difficult to prove except for some thin speleothems.

Adsorption of N,N,N′,N′-Tetraoctyl Diglycolamide on Hypercrosslinked Polysterene from a Supercritical Carbon Dioxide Medium

open access: yesMolecules, 2021
The work considers for the first time the preparation of sorbents based on hypercrosslinked polysterene (HCP) and chelating agent N,N,N′,N′-tetraoctyl diglycolamide (TODGA) by impregnation in the supercritical (SC) CO2 medium.

GNSS Profile from the Greenland Korth Expeditions in the Context of Satellite Data

open access: yesApplied Sciences, 2021
Over the last two decades, a small group of researchers repeatedly crossed the Greenland interior skiing along a 700-km long route from east to west, acquiring precise GNSS measurements at exactly the same locations.

Rapid Mass Loss in West Antarctica Revealed by Swarm Gravimetry in the Absence of GRACE

open access: yesGeophysical Research Letters, 2021
GRACE observations revealed that rapid mass loss in the West Antarctic Ice Sheet (WAIS) abruptly paused in 2015, followed by a much lower rate of mass loss ( 21.3±5.7 $21.3\pm 5.7$ Gt yr−1) until the decommissioning of GRACE in 2017.

Joint inversion of muon tomography and gravimetry - a resolving kernel approach [PDF]

open access: yes, 2014
Both muon tomography and gravimetry are geophysical methods that provide information on the density structure of the Earth's subsurface. Muon tomography measures the natural flux of cosmic muons and its attenuation produced by the screening effect of the
