The NetStation GPR: A Tool for Conducting Lander-Based 3-D Investigations of Martian Subsurface Structure, Stratigraphy, and Volatile Distribution

6 septembre 2013

The NetStation GPR is a stationary, impulse, multiband polarimentric HF GPR, designed to conduct geologic and volatile-related investigations of the Martian near- and deep-subsurface (~10 m - 1 km).

WISDOM GPR performance assessment in a cold artificial environment

6 septembre 2013

The WISDOM (Water Ice Subsurface Deposit Observation on Mars) GPR is one of the instruments that have been selected as part of the Pasteur payload of ESA's 2018 ExoMars Rover mission. WISDOM has been designed to obtain information about the nature of the subsurface along the rover path with the (...)

Can we use the planation surface concept to reconstruct the morphogenesis of New Caledonia,? First low temperature thermochronological data

6 septembre 2013

Nickel ore deposits of New Caledonia are formed in thick laterites and ferricretes developed on peridotites. Formation of this regolith remains unclear but combines stable phases with weathering profile development and preservation and mobile phases with regolith dismantling and fluvial (...)

WISDOM measurements in a cold artificial and controlled environment

5 février 2012

The WISDOM (500MHz - 3GHz) GPR is one of the instruments that have been selected as part of the Pasteur payload of ESA's 2018 ExoMars Rover mission. One of the main scientific objectives of the mission is to characterize the nature of the shallow sub-surface on Mars and WISDOM has been designed (...)

An atmospheric model designed for integration into coupled models of magma ocean planets. (poster)

3 février 2012

A 1D radiative-convective model of a thick (up to several hundreds of bars) H2O-CO2 atmosphere has been developped and coupled with a simple magma ocean interior model[1]. In this paper, we will focus on describing the atmospheric model. Preliminary results regarding observable parameters and (...)

Cooling of an early Earth magma ocean in interaction with the atmosphere. (poster)

3 février 2012

We developed a 1D convective model of a cooling magma ocean that we coupled with a 1D radiativeconvective model of a primitive atmosphere [4]. Our main objective is to estimate the cooling time when the retroaction with the atmosphere is taken into account. We first describe our model and (...)
