The photographer Grégoire Eloy from the ‘Tendance Floue’ collective is presenting an exhibition entitled ‘Troisième Nature’ at the Champs Libres in Rennes from 3 March to 21 September 2025.
From the glaciers of the Pyrenees to the foreshore of Finistère, this exhibition offers a photographic journey through the geological, forest and marine landscapes explored by Grégoire Eloy (winner of the prestigious Niépce Prize in 2021) over the past ten years.
All these projects attempt to understand the issues related to the formation and evolution of matter and the environment, alongside scientists specialising in matter and living organisms. At the crossroads of documentary and experimentation, Grégoire Eloy’s work mixes scales and techniques. He gives us an immersive vision of this experience of the natural environment, like an initiation rite that the photographer imposes on himself to better enter into the intimacy of the landscape.
Between October 2023 and May 2024, Grégoire Eloy notably followed our colleagues Jacques Grall and Vincent Le Garrec from the IUEM benthic observatory in the field and in the laboratory.

The 2024 Seignelay Prize of the Western Brittany Committee of the French Institute of the Sea and the National Chamber of Maritime Brokers of France will be awarded during their General Assembly at the CCI Finistère on Thursday, March 6, 2025, to François Gokce, a master’s student at IUEM/UBO.

The purpose of this prize is to reward a student for their work in favor of the sea and to support them in continuing their studies, entering professional life, or carrying out a maritime project.

This year, the award goes to François Gokce for his master’s thesis within the “Applied Economics for Agriculture, the Sea, and the Environment” (E2AME) – Blue Economy track.

He will notably receive a prize valued at 1,000 euros.

Congratulations to François, who was also the first work-study student at Amure during the 2023-24 academic year!

In March 2025, 32 high school students from Brest will be embarking on a scientific and civic adventure with the creation of a Club Jeunes Océan – an initiative launched by the IRD in partnership with Surfrider Foundation Europe. Supervised by their teachers and an oceanography researcher from the institute, they will learn about the scientific approach to exploring the impact of marine waste and how to take concrete action to protect the environment.

The Young Ocean Clubs initiative launched by the IRD is part of ‘2025, Year of the Sea’, in preparation for the United Nations Conference on the Oceans, to be held in Nice in June 2025. Seven clubs have been launched in mainland France, overseas France and Africa. Supervised by four teachers of Life and Earth Sciences, Physics and Chemistry, History and Geography and French, the Brest branch will benefit from the scientific support of Christophe Maes, a researcher at LOPS (Physical and Space Oceanography Laboratory). A specialist in the dispersal of plastics at sea, he is studying their pathway on a global scale to better understand their impact and propose solutions.

Field trips to analyse coastal pollution
The Club Jeunes Océan programme is organised around eight sessions combining awareness-raising, an introduction to the scientific approach and practical experience. After an introduction to the issues involved in protecting the oceans, the pupils will head out to the coast to collect and analyse waste. With the support of our researcher, and using the data collected in the field, the students will carry out an investigation to try and understand where the waste comes from, the behaviour that causes it and how to take effective action to limit this pollution.

A plea to defend their ideas to the public
As well as making scientific observations, the students will be asked to draw up a plea to raise awareness among the public and decision-makers. They will work together with their supervisors to determine the awareness-raising action they want to take, thus becoming true ambassadors for the preservation of the oceans.

In 2023, the IPCC deemed it highly unlikely that the AMOC would collapse by the end of the century. In a recent letter, some experts believe that this risk has been underestimated. What is this current? How does it influence the climate? Is its collapse imminent? What would be the consequences?

Global warming is threatening a vast set of marine currents in the Atlantic Ocean: the AMOC. According to 43 international experts, we have underestimated the risks of shutting it down. What would be the consequences?

The AMOC is a system of ocean currents, of which the Gulf Stream is a part. It is one of the major drivers of climate, playing a crucial role in redistributing heat around the planet, and is one of the reasons why our climate in Western Europe is temperate. In a recent letter, experts stress the collateral effects of its slowing down, or even its collapse. Because this is now a probable risk.
