Article
Full-text available
Observations of changes in terrestrial water storage (TWS) obtained from the satellite mission GRACE (Gravity Recovery and Climate Experiment) have frequently been used for water cycle studies and for the improvement of hydrological models by means of calibration and data assimilation. However, due to a low spatial resolution of the gravity field m...
Article
Along-strike variation in the geometry of lithospheric structures is a key control parameter for the occurrence and propagation of major interplate earthquakes in subduction and collision zones. The lateral segmentation of the Himalayan arc is now well-established from various observations, including topography, gravity anomalies, exhumation rates,...

Article
The emergence of high resolution satellite measurements of the gravitational field (GOCE mission) offers promising perspectives for the study of the Earth’s interior. These new data call for the development of innovant analysis and interpretation methods. Here we combine a forward prism computation with a Bayesian resolution approach to invert for...

Article
We present a new analytical solution to compute the full-tensor gravity gradient due to a body mass of uniform density with arbitrary geometry. The solution is an extension of an existing analytical computation of gravitational anomalies of a polyhedron source, based on a transition of the general expressions from surface to line integrals. These d...
Thesis
Full-text available
Nowadays, the scientific community has at its disposal gravity and gravity gradient datasets with unprecedented accuracy and spatial resolution that enhances our knowledge of Earth gravitational field at various scales and wavelengths, obtained from ground to satellite measurements. In parallel with gravimetry, the advancement of satellite observat...
Article
Estimating how topography is maintained provides insights into the different factors responsible for surface deformations and their relative roles. Here we develop a new and simple approach to assess the degree of isostatic compensation of continental topography at regional scale from GOCE gravity gradients. We calculate the ratio between the radia...

Aktivitas tektonik yang terjadi di bumi merupakan hal yang masih terus diteliti sampai sekarang. Sumatera yang terletak pada area Sunda Megathrust, yang merupakan zona subduksi Lempeng Indo-Australia dan Lempeng Eurasia, mengakibatkan daerah ini rentan dengan aktivitas seismogenic. Salah satu akibat dari adanya pergerakan kedua lempeng ini adalah t...

Project
The primary goals are: (1) develop a multi-observation ensemble-based calibration and data assimilation (C/DA) methodology to combine observational data of model output variables (time series of gauge-based streamflow, GRACE/GRACE-FO total water storage variations, remotely-sensed extent and level of surface water bodies, snow cover, glacier mass change and streamflow) with hydrological models in an optimal manner. (2) exploit this methodology with the global hydrological model WaterGAP to provide an improved quantitative assessment of freshwater fluxes and storages including their uncertainties in response to climate and anthropogenic forcing. To reach these goals, nine partners work together, collaborating with two Mercator fellows. The Goethe University Frankfurt and the University of Bonn coordinate the project.
Project
What controls the width and partitioning of deformation and seismicity in continental orogens? To tackle this question, the project develops innovative geodynamic models of two target orogens, the Yakutat collision (Alaska - NW Canada) and the Rif – Atlas (NW Africa), in order to characterize the main dynamic processes controlling the spatial partitioning and distribution of strain and seismicity (role of inherited lithospheric structural heritage, thermal state and rheology of the lithosphere, gravitational forces, ...) DefDyCor is a project funded by the French "Agence Nationale de la Recherche" between 2012 and 2017.
