The end of the sea as a profession? Podcast on RFI

At the global level, fish represents a 33 billion euro market, a market that has been growing for decades. Since 1950, fisheries and aquaculture production (capture fisheries and aquatic farms) has increased ninefold, according to the FAO.

On the occasion of World Oceans Day 2022, our colleague Patrice Brehmer, a IRD researcher in Marine Ecology based at the Sub-Regional Fisheries Commission (SRFC) in Dakar, participated in the 7 billion neighbours podcast series on Radio France Internationale (RFI).

Plastic: the great disaster, on France Culture

GDR-plolymeres & Ocean

It is estimated that between eight and eleven million tonnes of plastic waste are dumped into the seas every year. This waste turns into microparticles, wreaking havoc on oceanic flora and fauna.

At the invitation of Florian Delorme, our colleague Ika Paul-Pont, CNRS research fellow in marine ecotoxicology, took part in the Cultures Monde programme on 8 June 2022 alongside Pascale Fabre, physical chemist, research director at CNRS, Laboratoire Charles Coulomb, director of the GDR “Polymer and Oceans”.

Si Quelque Chose Doit Surgir…

, ,

If Something Must Arise…

Behind this enigmatic title, Jean-Manuel Warnet offers us an immersive experience, at once sensory, literary, poetic and scientific.

Jean-Manuel is a lecturer in theatre studies at the UBO, he also teaches literature and directs the company Les Filles de la Pluie.

“Si Quelque Chose Doit Surgir…” is a radio creation that he wrote and produced with Victor Blanchard at the end of an artist residency on a scientific mission in Greenland with our colleagues from LIA BeBEST. First presented as a show, this creation is finally audible in its studio format, on the OUFIPO webradio site. You can listen to it in stereo, under headphones and wrapped up in a fleece. All the details and the starting click are here:

Have a good time listening!

The silicon cycle at “la Méthode Scientifique” radio program, May 5, 2021 at 4pm

,

Silicon. Why should we be interested in this element? Because it is particularly abundant in the form of silica and silicate minerals on the planet Earth and on other terrestrial planets (Mercury, Venus, Mars). If on Earth living organisms are based on the carbon cycle, essential organisms of marine life (diatoms, radiolarians, a good part of sponges, …) require silicon to build their internal or external structures. Without silicon, the biological carbon pump loses much of its efficiency. What are the sources and sinks of silicon in the ocean? What is the production of biogenic silica in the ocean? How is the silicon cycle evolving in response to climate change and anthropogenic perturbations?

These are the questions that Paul Tréguer (LEMAR, IUEM-UBO) answered on France Culture, during the program “La Méthode Scientifique” on Wednesday, May 5, at 4:00 pm, a program to which Anne Alexandre (CEREGE, CNRS) was also invited.
