Absolute marine gravimetry with matter-wave interferometry
Nature Communications, 2018 Measuring gravity from an aircraft or a ship is essential in geodesy, geophysics, mineral and hydrocarbon exploration, and navigation. Today, only relative sensors are available for onboard gravimetry.

IEEE Transactions on Instrumentation and Measurement, 2021 The accuracy of gravity disturbance horizontal components is an obstacle in strapdown airborne vector gravimetry at present. In the strapdown inertial navigation system (SINS) field, the rotation modulation technique has been put into practice to improve

THE SUCCESS OF SATELLITE GRAVIMETRY IN GEOPHYSICAL INVESTIGATIONS [PDF]
Geological BehaviorTerrestrial measurements of gravity data are limited to only accessible areas. Areas that are not easily accessible due to lack of access route, security, cost etc. are found unfavorable for terrestrial measurements.

Precise levelling data processing near terraced landforms
Geodesy and Cartography, 2014 Precise levelling results are affected by the Earth’s gravity field, especially in areas of abrupt changes of landscape, such as terraced landforms. To eliminate the effect of the gravity field gradient, corrections need to be used in precise levelling ...

Hidden pressurized fluids prior to the 2014 phreatic eruption at Mt Ontake
Nature Communications, 2022 Phreatic volcanic eruptions can be unexpected and devastating. Here the authors, using seismic-based methodologies, find that pressurized fluids accumulated 5 months before the deadly phreatic eruption at Mt Ontake; a period previously considered as ...
