As an author and a director

I have worked for many clients, institutional, public or private, and for television. Here are some examples. Extracts from a few films. I would change them from time to time. Always for the memory. So that it will still going on in the internet limbo, and in my memory.

Phare 2002

The PHARE oceanographic campaign took place from April 30 to June 3, 2002 in the Pacific off the coast of Mexico. The objective of CNRS and Ifremer researchers is to study the animal communities living on and around hydrothermal springs which are found in the depths of the sea, due to volcanic activity. The fauna of these very unique ecosystems supports extreme temperature conditions and the highest concentrations of sulfide and metals on our planet. Cut off from the sun, these ecosystems are based on chemosynthesis: bacteria use the oxidizing energy of dissolved minerals, emitted by smokers, to make organic matter. To explore these ocean trenches, scientists use Victor, a multi-instrument robot capable of working more than 6,000 m deep, fully remote-controlled from the surface.

Electrostatic

A session with a group of students in the electrostatic room of the Palais de la Découverte in Paris. The experiments presented imply high voltages (300,000 V) but they are safe because they are associated with very low currents. These currents only occur during the charging and discharging of the elements. When the discharge takes place in air, it gives rise to a blue glow (egret) or to sparks due to ignition arcs. Two young girls mounted on a plateau brought to a high potential are out of danger, because isolated from the outside. Their loaded hair stands on their heads.

Mission EXPRESSO 1997

Expresso (Experiment for regional sources and sinks of oxidants) is the name of an international mission which aimed to study the emissions of tropical ecosystems and their transformation in the lower atmosphere leading to the production of ozone. The experiments take place in the Congo and the Central African Republic in the forest areas and at the forest-savannah interface. Researchers, French, American and African, analyze components of the atmosphere from the ground up to an altitude of about 1,000 meters. They use a 55 m high tower. The emissions consist of gases emitted by the soil (such as methane), plants (certain hydrocarbons, including isoprene) and by soot particles due to savannah or household fires. The production of ozone due to the physicochemical reactions between these elements undoubtedly has a significant influence on the evolution of the climate.
