Marine pollution as seen by ultrafast cameras

Marine pollution

Ultrafast cameras unveil processes that are invisible to the naked eye. At Mines Alès, Pierre Slangen, a specialist in applied optics, uses them to build advanced technology devices and thus to understand how gases and liquids are diffused during environmental disasters.     Certain physical phenomena occur in such small …

Marine oil pollution detected from space

oil pollution

Whether it is due to oil spills or cleaning out of tanks at sea, radar satellites can detect any oil slick on the ocean’s surface. Over 15 years ago, René Garello and his team from IMT Atlantique worked on the first proof of concept for this idea to monitor oil …

Being in such high demand, it is extracted in conditions that aren’t always respectful of the environment. With the increasing scarcity of sand and the sometimes devastating consequences of mining at beaches, …

Bioplastics: “still a long road to higher performance”

Bioplastics, Mines Douai

As required by environmental transition, materials of the future must be “greener”. Bioplastics in particular have become a main focus of attention, and are often presented as the solution to the pollution caused by the plastics we use every day, which can take hundreds of years to decompose. Patricia Krawczak, …

An ocean of environmental data to be processed

René Garello, Vigisat, Océan, Télécom Bretagne, Ocean

If nowadays we can detect icebergs along the route of the Vendée Globe, track and identify ships causing pollution from space, and define ecological corridors and reserves for the protection of animal species, it is largely thanks to stations which receive and process satellite images in real time, and the …
