Abstract |
We present a new procedure to describe the one-dimensional thermodynamical state and mineralogy of any Earth-like planetary mantle, with Mars as an example. The model parameters are directly related to expected results from a geophysical network mission, in this case electromagnetic, geodetic, and seismological processed observations supplemented with laboratory measurements. We describe the internal structure of the planet in terms of a one-dimensional model depending on a set of eight parameters: for the crust, the thickness and the mean density, for the mantle, the bulk volume fraction of iron, the olivine volume fraction, the pressure gradient, and the temperature profile, and for the core, its mass and radius. Currently, available geophysical and geochemical knowledge constrains the range of the parameter values. In the present paper, we develop the forward problem and present the governing equations from which synthetic data are computed using a set of parameter values. Among all Martian models fitting the currently available knowledge, we select eight candidate models for which we compute synthetic network science data sets. The synergy between the three geophysical experiments of electromagnetic sounding, geodesy, and seismology is emphasized. The stochastic inversion of the synthetic data sets will be presented in a companion paper. |

Abstract |
L'article suivant aborde les paysages polaires à travers la production récente d'un cédérom consacré à l'analyse de paysages depuis le sol en milieu arctique. Après avoir rappelé brièvement l'ambiguïté des relations entre géographie et paysage, on évoque l'évolution des représentations des paysages et des zones polaires chez nos contemporains, avant de montrer comment les nouveaux médias autorisent une approche renouvelée des paysages. Le céderont, sur lequel on focalise progressivement le propos, sert de fil conducteur à cette réflexion sur le paysage polaire, considéré tout à la fois comme objet d'étude et comme espace expérimental. |

Abstract |
Climate change is a key issue, especially in the Arctic. However, this general observation is not sufficient to determine the consequences of this phenomenon since the impact of climate change varies with geographical position and local conditions in different environmental contexts. The study area is located at 79?N, in Kongsfjorden (Svalbard). Botanical observations and temperature measurements, remote sensing and topographical indices are input into a Geographical Information System. These GIS layers are then computed to provide variables that can give a statistical explanation of the temperature and vegetation distribution at high resolution. |
