Absolute gravity measurements at Brest (France) between 1998 and 2022 Open
Repeated absolute gravity measurements, conducted once or twice per year, have proven valuable for quantifying slow vertical land motion with a precision better than 0.4 µGal yr−1 (1 µGal = 10−8 m s−2) after a decade or more. This precisio…

Airborne absolute gravimetry with a quantum sensor, comparison with classical technologies Open
We report an airborne gravity survey with an absolute gravimeter based on atom interferometry and two relative gravimeters: a classical LaCoste\&Romberg (L\&R) and a novel iMAR strap-down Inertial Measurement Unit (IMU). We estimated measu…

Data heterogeneity and oldness, two difficulties to overcome for the world seabed sediment mapping Open
A global seabed sediment map has been developed since 1995 to provide a necessary tool for different needs. This project is not completely original since it had already been done in 1912 when the French hydrographic Office and the Universi…
