The dynamics of the Earth, from its core to its atmosphere

ZheoPS-RTK (Z Positioning System – Real Time Kinematic) est un système de mesure topographique (uniquement Z) utilisable en terrain couvert (milieu urbain, forestier et souterrain). Il prend en compte l'effet des variations météorologiques pour apporter une précision décimétrique à l'altitude du point mesuré. Cette mesure peut être synchronisée avec celle d'un instrument de prospection géophysique et une acquisition autonome pourra être aussi réalisée via une application pour smartphone…

This second episode looks at the work of scientists at the Grenoble Institute of Geosciences who are studying the climate change effect on glacier behaviour. In mountainous and polar regions, glaciologists such as Fanny Brun measure the melting glaciers and collect ice samples, sometimes under extreme conditions, as evidence of climate change over time. Laboratory analyses are used to understand the climate change effect on glacier behaviour. Gerhard Krinner, a…

Episode 2: As the melting of ice intensifies and glaciers erode year after year, threatening to accelerate the rise in water levels, researchers from the CNRS are closely monitoring the Argentière glacier (Alps) using an original method to better understand and measure its movements.

Due to climate change, the Argentière glacier in the French Alps has been losing a metre of thickness every year for the past 30 years. A team of scientists has equipped the icy giant with more than 100 sensors to listen to its inner workings for a month.

Antarctica is a hostile territory due to its isolation and extreme climatic conditions, but it is also a place of unique opportunities for research and has been a protected area reserved for scientific exploration since the Madrid Protocol was signed in 1991. This film presents the work of four researchers from various fields who went to Antarctica to conduct their research project: studying animal behaviour, observing the Earth's magnetic fields, collecting and analysing micrometeorites and…

At the "Ondes et Matière ' " laboratory in Aquitaine, soap bubbles have become a study subject for detecting instability and turbulence. The aim is to simulate flux and flows to create faithful models of vortexes comparable to natural phenomena such as cyclones, hurricanes and typhoons.

In a Grenoble laboratory, researchers have access to a unique instrument: the largest turntable in the world, 14 meters in diameter. They benefit from a remarkable instrument for modeling experimentally the effect of the Coriolis Force on atmospheric and ocean flow, which are major phenomena on our planet.

Flying an airplane into a thunderstorm may not sound like a good idea. Unless you are a physicist. Scientists from the Exaedre project have led an exceptional mission to study the physics of lightning from up close.

How can the clouds that may be behind violent storms and floods be identified? This report sets out for the Ardèche region in southeastern France, where scientists track dangerous clouds using a lidar, a cutting-edge instrument that helps elucidate how they form, and more generally how to anticipate extreme weather events.

Ce nouvel épisode d'Un zeste pour la planète nous parle d'éoliennes... Mais surtout d'une machine extraordinaire, qui permet de simuler la rotation de la Terre et ses écoulements atmosphériques pour réaliser des expériences inédites. Un instrument précieux lorsqu'il s'agit d'implanter au mieux des parcs éoliens en haute mer, là où ils sont soumis à diverses forces terrestres...

Discover the studies behind the statistics of 6th IPCC report and the research work of scientists who aim to gain a better understanding of climate change and its impact. This first episode presents the work carried out by members of the LSCE (Laboratoire des sciences du climat et de l'environnement) at the Traînou site in France. These scientists collect air samples using stratospheric balloons that reach altitudes of over 30 km. The analysis results of these samples are then used…

This sixth episode traces the current development of the Amazon's climate through the involvement of local inhabitants and the analysis of satellite images. The findings are clear, there is more drought in the south, more humidity in the north. With cascading consequences for the global climate...

This fourth episode is devoted to the sets of equations that represent the physical mechanisms that affect our planet, such as the circulation of water and carbon. How are these models developed? What are they used for? Meet the scientists who are sounding the alarm with the help of these models.

Certains incendies, comme ceux qui se sont déclarés dans la province de l'Alberta au Canada depuis mai 2023, semblent incontrôlables. Comment anticiper un phénomène aussi variable et imprévisible ? Ce reportage vous emmène en Corse, où des expériences de terrain et des simulations permettent aux scientifiques de mieux comprendre la dynamique des feux de forêt.

As a consequence of the demographic explosion, the fresh water shortage will be one of the major issues in the world in the decades to come. Among the existing solutions, the water desalination is meeting expansion. This film presents the principles of the different methods of seawater desalination and their implementations. It draws up the balance sheet of the actual researches in this domain and it deals also with the socio-economical stakes which depend on it.

Lutter contre la pollution atmosphérique urbaine suppose la fiabilité des mesures et l'information active du citoyen. Le projet SMILE propose de mailler la ville en déployant une flottille de capteurs low-cost interconnectés rendus précis grâce à un procédé nouveau d'auto-calibration. L'emploi de drones permettra de générer des cartographies 3D à l'échelle d'une rue sur une plateforme citoyenne où se rencontreront toutes les parties prenantes : citoyens, académiques, décideurs politiques, monde…
