The complexity of the climate system means that for the reconstruction of past variations, the use of a multiplicity of proxy indicators is mandatory. Polar ice cores...

Remote-sensing is an adequate tool for monitoring polar ice-sheets. In visible and infrared spectral ranges, the informations are coming from the upper top of the snow...

L'albédo de la surface antarctique Joue un rôle important dans les études climatologiques. Essentiellement deux facteurs peuvent modifier sa valeur: la taille des...

Under surface loads, the Earth depresses in order to restore a state of isostatic equilibrium. Conversely, when these loads disappear, the surface rises again to...

The high southern latitude atmosphere remains poorly documented. The understanding of the biogeochemical sulphur cycle is a critical aspect for climate change studies...

Nitrate ions (NO3-) found in Antarctic snows stem from the degradation of nitrogen oxydes (NOx = NO + NO2) in the atmosphere. At sites with low snow accumulation rates...

The main goals of the present study are, first, determination of the relationship between local air temperature and snow isotope composition at Vostok Station (East...

The earth's climatic system consists in several components which strongly interact (atmosphere, ice sheets, oceans, lithosphere and biosphere). Numerical modelling is...

This work aims at better understanding the atmospheric sulfur cycle in Antarctica through the use of an Atmospheric General Circulation Model (AGCM). The "Antarctic"...

The Southern Ocean is a location where major climate changes occurred over the last century, accompanied with an important level of human exploitation of natural...

The Antarctic Surface Mass Balance (SMB, i.e. the snow accumulation from which we subtract ablation by sublimation, run-off or erosion) is a major yet badly known...

The snow surface on the Antarctic Plateau plays an important role to study the surface mass and energy balance. Its characteristics depend on interactions between the...

The shelters of the Concordia/DomeC Magnetic Observatory, area of the base called "the magnetic village".

Inside the "Absolute Measurements" shelter at Concordia/Dome C Magnetic Observatory: in the foreground, the orange theodolite used to make absolute measurements of the...

Shelters of the Concordia/Dome C Magnetic Observatory are getting snowier every year. Snowdrifts are created because of the wind sweeping fine ice particles over...

Vault of the 'Variometer' shelter at the Concordia/Dome C Magnetic Observatory. The depth of 2 meters in the ice leads to a rapid formation of frost. The staircase to...

The shelters of the Magnetic Observatory of Dumont d'Urville, area of the base called "the magnetic village".

Inside the 'Variometer' shelter at the Dumont d'Urville Magnetic Observatory: on the ceiling, the white bottle of the scalar magnetometer used to measure the intensity...
