Polymères et Océans


27 – 29 juin 2022 en présentiel à BREST, à Brest-Arena

Les enjeux environnementaux liés aux déchets plastiques sont unanimement reconnus. Les institutions nationales et internationales en ont fait un sujet primordial notamment avec la décennie des sciences océaniques (2021-2030).

Dans un domaine où les défis sont multiples et pluridisciplinaires, ces journées sont l’occasion de fédérer la communauté scientifique autour du devenir et des impacts des polymères en milieux aquatique et aérien, partager les derniers résultats et discuter perspectives et solutions.

Depuis 2019, le GDR Polymères et Océans organise une conférence annuelle. Cette 3ème édition poursuit l’élan des 2 premières conférences à l’Université de Paris-Créteil en 2019 et à l’Université de Pau en 2021.

Ces journées seront suivies les 30 juin et 1er juillet 2022 des rencontres nationales « Plastiques, changement de cap ! » à BREST ARENA.

Venez nombreux et profitez de la pointe bretonne

Sea-Eu programme, Maltese season for LEMAR

In the framework of the SEA-EU project, our Maltese colleagues organised a workshop entitled “Towards a sustainable blue economy in 2030: Exploring opportunities for innovation and collaboration”. This workshop took place in two parts:

  • A one-day presentation (remote event) on 24 June 2021
  • A 3-day face-to-face bootcamp, which took place in Malta, on the University of Malta Valletta campus, from 15 to 17 September.

A team of 4 researchers and students from the UBO was selected to participate (based on their background and motivation).

Among them, 2 of our colleagues represented LEMAR:

Charlotte Corporeau for her research actions in biology at the sea-health interface for the Blue economy.
Mariana Ventura, PhD student in marine biotechnology at LEMAR

Also present in the Brest delegation: Jean-Marie Vient, PhD student in marine geology at the Ocean Geosciences Laboratory and Bertrand Le Gallic, Lecturer and researcher in marine economy at AMURE.

MYCTOPHIDAE, a travel in deep seas | A Festival Ressac exhibition

, ,

The oceans? A vastness, a wealth and one of the keys to the functioning of life on our planet. And yet the mysteries are still many. In this partially known world, lanternfish or myctophidae, are very abundant from the equator to the coldest areas, from the surface to several hundred metres deep.

Who are they, what do they look like, what are they doing there? How can we unravel the enigma of this environment that is impossible to observe with our eyes?


Led by Gildas Roudaut, some scientists (IRD, CNRS, MNHN, CPS) have initiated a dialogue with a class of Applied Arts (STD2A) of the Vauban High School in Brest.

These exchanges gave rise to an exhibition, MYCTOPHIDAE, presented at the IUEM, and a magazine, La Lanterne, created with the support of the UBO and the IRD as part of the Ressac Festival .

The exhibition can be visited at the Bibiothèque Universitaire du Bouguen (10, av. Victor le Gorgeu, Brest), from 18 November 2019 to 6 January 2020.

It is also available in pDF format (low resolution), on this page.

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.

Have a good time listening!

Immersion Sciences 2021, with Ika Paul-Pont


Attracting young Bretons to scientific fields of study

Our biologist colleague Ika Paul-Pont took part in the 10th edition of the Immersion Sciences operation.

Demystifying the idea that young people have of scientific careers in order to encourage them to take up these courses of study after the baccalauréat is the ambition of the Immersion Sciences operation run by the Académie de Rennes, the Région Bretagne and the CNRS. Since 2011, at the end of March, around sixty students have usually had the chance to discover research careers for a week at the Île-Tudy nautical centre, in contact with passionate scientists.

Due to the health crisis, it was not possible this year to welcome a group of high school students to the Île-Tudy Nautical Centre, and the operation took place over two half-days of video-conferences with researchers organised on 30 and 31 March, before visits to laboratories at the end of the school year.

Ika Paul-Pont, the epidemiologist Caroline Rault and the physicist Maud Guézo, were able to talk about their activities and their careers, to dispel some of the persistent myths about researchers and to introduce young people to the world of research and scientific careers, in order to make them want to “do” science.

It was also an opportunity for Ika to talk about plastic pollution. The students were very concerned and their questions focused on both the facts (is it not too late? and in relation to climate change? what is the role of governments?) and on solutions (cleaning robots, new polymers).

We look forward to the 2022 edition!
