Publication: Key figures on climate change in Brittany – 2025 edition

Climate: a new publication raises the alarm about Brittany’s future at +4°C

In May 2025, the Observatoire de l’Environnement en Bretagne (OEB) published a new edition of its brochure ‘Key figures on climate change in Brittany’, a reference document highlighting the expected effects of climate change in the region by 2100. This is the first regional publication in France to be based on the reference trajectory for adaptation to climate change (TRACC) set by the French government.

The report paints an alarming picture: rising temperatures, more intense droughts, increased risk of flooding and more frequent extreme weather events. Clear data, remarkably presented through extensive data visualisation in the form of maps, graphs and infographics, is made available to help elected officials, local authorities, businesses and citizens better understand the challenges ahead.

This work draws on extensive scientific expertise and was carried out with significant contributions from researchers and engineers from the European Institute for Marine Studies (IUEM). Among them, Anne-Marie Tréguier, Guillaume Charria, Alain Hénaff and Peggy Rimmelin Maury participated in the analysis and drafting of this brochure, particularly on coastal and maritime phenomena.

The publication is accompanied by a summary poster entitled ‘Brittany in a France at +4°C’ and a regularly updated web version. Available in all libraries, media libraries and secondary schools in the region, it embodies a desire to make scientific information accessible to all.

Bridging Oceans: SAMOS launches ambitious Erasmus+ partnership in Ocean Sciences education between South Africa & Europe

The opening of the South African Master of Ocean Sciences (SAMOS) project was welcomed by the choir of Nelson Mandela University, which delivered a heartfelt introduction, extending a warm greeting to all attendees at this momentous occasion.

The launch took place from 8-10 April 2025, hosted in Gqeberha, South Africa, Nelson Mandela University. This marked the beginning of a dynamic three-year initiative, coordinated by the University of Brest (France), and funded by the European Commission under the Erasmus+ Capacity Building in the field of Higher Education (CBHE) programme.

SAMOS Project’s objectives

The SAMOS project was developed to co-create a new multidisciplinary Master of Ocean Sciences degree in South Africa with both a taught and a research component. This inclusive initiative is a collaborative effort between nine South African universities, 5 of which are historically disadvantaged universities, the National Research Foundation, and five European partner institutions, aimed at strengthening education, research and innovation in support of the sustainable blue economy*.

Strong support from the South African authorities

The opening day featured remarks from key stakeholders, who reflected on the years of groundwork that led to this milestone and emphasised the strategic value of advancing ocean sciences.

At the heart of the project lies the goal of equipping the next generation of scientists with the tools and knowledge to manage ocean resources responsibly. Dr. Muki Moeng, DVC Teaching and Learning at Nelson Mandela University, highlighted the direct contribution of the SAMOS programme to sustainable practices and responsible resource management, aligning closely with South Africa’s Vision 2030.

The national importance of the programme was reinforced by Dr. Whitfield Green, CEO of the Council on Higher Education, and Dr. Gilbert Siko, Acting Chief Director for Marine and Polar Research at the Department of Science, Technology and Innovation. They emphasised the programme’s alignment with national development goals – particularly the internationalisation of higher education, the strengthening of ocean sciences capacity, and adherence to CHE’s Quality Assurance framework for local and cross-border qualifications.

M. Garth van Heerden, representing the National Research Foundation, emphasised the objectives of the NRF to go beyond financial support, and develop strong relationships with universities and scientists to ensure adequate support to specific needs expressed by the laters.

A stronger France – South Africa partnership

The legacy and strength of Franco-South African cooperation were also celebrated. Dr. Francis Marsac, representing IRD, underscored how the SAMOS project represents an important result and continuation of more than two decades of collaborative efforts in marine sciences between the two countries. Prof. Fred Jean, head of the European Institute for Marine Studies (Brest, France), praised the programme’s high academic quality-made possible through the deep commitment and cohesion of the consortium partners.

Echoing this, M. Aurélien Leynet, Attaché for science and academic cooperation at the French Embassy, underscored the strategic value of such partnerships, strengthening opportunities for collaboration and mobility.

An inclusive and innovative project

The programme’s inclusivity and transformative potential were underscored by contributions from several partner universities. Dr. Nomakwezi Mzilikazi, DVC for Research, Innovation, and Strategic Partnerships at Rhodes University, stressed the need to strengthen capacity in Ocean Sciences that originated the design of the SAMOS curriculum and project as a whole.

Prof. Andrew Leitch, representing the University of Fort Hare, spoke to the vital role of Historically Disadvantaged Universities in SAMOS. He then called for close attention to student supervision to ensure robust academic support. Prof. Nosisi Feza, DVC for Research at Walter Sisulu University, emphasised the imperative to drive impactful research and innovation, linking SAMOS directly to the achievement of the Sustainable Development Goals. Finally, Prof. Mudali from the University of Zululand highlighted the multidisciplinary nature of their science faculty – a unique asset that will enrich the SAMOS consortium and foster integrated approaches to ocean sciences education and research.

Further in the morning, the Advisory Board meeting was held in a hybrid format. Members were introduced, the Memorandum of Agreement was discussed, and strategic planning was initiated. After a networking lunch, the afternoon continued with the Steering Committee session focusing on project management and implementation monitoring.

A structured work dynamic

The remainder of the days were dedicated to outlining key actions and finalising the implementation strategy, with the Work Package (WP) leaders presenting their activities and deliverables. Dedicated working group sessions brought participants together in thematic teams on governance, teaching plan, capacity-building and communication and dissemination, which reinforced collaborative engagement and set clear paths for project execution.

The final day focused on highlighting the research components of the project and introduced the twinning programme for academics. The WP leaders delivered feedback from the previous day’s group sessions, summarising key outcomes and next steps. The day concluded with continued engagement from all members of the SAMOS consortium.

A solid foundation for the future

As the project enters its implementation phase, the momentum generated during the kick-off event has laid a solid foundation for meaningful, academic exchange and capacity building. Through its innovative approach and international collaboration, SAMOS is well placed to make a significant contribution to the advancement of the sustainable blue economy and toward shaping the future of ocean sciences in higher education across South Africa and beyond.

The RZA 2025 Winter School: land and sea dynamics

Dynamics between land and sea: a Breizh history of time

How can we think about socio-ecosystems through the prism of temporalities? This was the central question that animated the 2025 edition of the Winter School of the Réseau des Zones Ateliers (RZA), organised this year in the unique setting of the bay of Brest, in Logonna-Daoulas, from 3 to 7 March 2025.

For three days, 25 young researchers (doctoral and post-doctoral students, ATER) immersed themselves in the dynamics of the land-sea continuum, exploring how time scales influence scientific research, land management and public policy.

An interdisciplinary and immersive programme

On the programme for this intense week, under a radiant sun:

The winter school opened with three inspiring lectures and talks:

  • The carbon cycle on the scale of geological time by Stefan Lalonde,
  • The disturbances of long time by Rémi Beau
  • The time of increased meaning by Olivier Ragueneau

Four themed workshops to experiment

The participants were divided into four groups, to enable them to follow four workshops each exploring a key axis of the land-sea continuum:

  • Water quality and the transfer of contaminants in the land-sea continuum.
  • This workshop focused on issues related to water quality at the bottom of the bay of Brest, including toxic microalgae (Alexandrium minutum) and antibiotic resistance. Samples and measurements were taken at sea (with the ship Hésione) and in the surrounding rivers to assess the physicochemical and bacteriological parameters in the land-sea continuum. The samples were analysed in a mobile laboratory at Moulin Mer.
  • Socio-ecosystem trajectory of an agro-marine system: Ecological time and the time of societies, complexity of renewed governance
  • This workshop explored the socio-ecosystemic trajectory of the land-sea continuum in the roadstead of Brest, through a multidisciplinary approach combining biology, ecology, history, archaeology, sociology and governance. Four sub-workshops offered opportunities for field observation, meetings with local stakeholders (oyster and scallop farmers, fishermen, farmers, elected representatives of Brest Métropole, TerraRade) and collective reflections on the ecological, social and political dynamics at work in this agro-marine territory. The aim was to foster a renewed understanding of this continuum and to consider more coherent and sustainable forms of governance.
  • Methodology in arts and sciences – Thinking continuum and temporalities: The contribution of arts and sciences to renewing our view of socio-ecosystems.
  • This workshop offered a transdisciplinary exploration of the links between the arts, sciences and society to renew our relationship with coastal socio-ecosystems and watersheds. Using concrete examples (Molène, Aulne Maritime, Piave river), the participants discovered research-creation and research-action approaches integrating long time frames, traces and sensitive representations of the living world. The aim was to develop innovative methods of co-constructing research and to foster a common culture across disciplines through artistic practices.
  • Coastal risk management through role-playing in a serious game.
  • This workshop offered a serious game scenario to explore the issues of coastal risk management in a fictitious but realistic context with the serious game developed by AMURE; Coastal Risks in Plonevez-les-Flots. The participants, in the shoes of agents from different municipal services, had to arbitrate between budgetary constraints, the expectations of the inhabitants and reducing vulnerability to climate change. The aim is to promote a systemic and interdisciplinary approach to the complex issues at the Human-Nature interface, while questioning collaborative practices.

Two evenings were organised: one on the scientific mediation of the Brest Iroise Workshop Zone, with: the ISblue SEALEX-PACTE Project stand (Clara Valero and Lucas Bosseboeuf), the Evol’Iroise interactive poster (Sébastien Hervé & Aurélie Penaud) and the Virtual Reality stand (Maxime Kernec and Charlotte Gasne–Destaville) and a participatory workshop on the commitment of researchers organised by Mélanie Raimonet and Olivier Ragueneau.

An original and creative presentation

Throughout the week, the discussions were enriched by the PIBA troupe, which accompanied the participants in an innovative presentation combining science, radio narration and staging. A great way to explore how to convey the complexity of socio-ecosystems in a different way!

A space for dialogue and engagement

Far from being a simple academic seminar, this winter school was a real space for co-construction, promoting exchanges between disciplines and local stakeholders. How can we integrate issues of temporality into our research and actions? This question ran through all the discussions, and brought out new perspectives for thinking about socio-ecosystems.
 

“Troisième Nature” exhibition at the Champs-Libres, in Rennes

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.

Stand Up for Science !

Today, universities and research are under attack on an unprecedented scale. The offensive is particularly alarming in the United States, where research institutions, regulatory agencies, civil rights and the very foundations of democracy are being undermined by the Trump administration and Mr Musk’s Department of Government Efficiency (DOGE). International solidarity is all the more essential as Europe is facing similar threats.
Echoing the Stand-up for Science day initiated in the United States, calls for mobilisation actions were organised (marches, rallies, symposia, experimental presentations, etc.) on 7 March in every university town in France. The objective was clear: to defend the sciences and the humanities, academic freedom and the university as pillars of a democratic society.
To take part in this appeal, a gathering was held in front of the IUEM at 12.30 pm. Largely attended by the IUEM community and our colleagues from the Technopôle, it was immortalised by a group photo (thanks to Sylvain Petek) and was the subject of articles in the local press.

Launch of an IRD Ocean Youth Club in Brest

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.

 

CNFGG thesis prize awarded to Arthur Avenas

French National Committee for Geodesy and Geophysics (CNFGG) thesis prize in the Geophysics category awarded to :

Arthur Avenas, UMR LOPS, for his thesis entitled ‘Tropical cyclone dynamics revealed by satellite observations of surface wind speed: the major contribution of the surface wind structure near the core’, prepared at the École nationale supérieure Mines-Télécom Atlantique Bretagne Pays de Loire and defended on 28 March 2024.

‘Tropical cyclone dynamics revealed by satellite observations of surface wind speeds: the major contribution of the surface wind structure near the core’.

Despite advances in the prediction of tropical cyclone tracks and wind speeds in the outer region, the numerical representation of the strongest winds associated with the most intense events remains an open question, mainly due to the small size of the cyclone core and the difficulty in understanding and resolving the turbulent exchanges between the ocean and atmosphere. Observational limitations have long hampered accurate measurements of the ocean surface near the core region in extreme wind conditions, while geostationary satellites help characterise cloud patterns but do not provide direct information on the air-sea interface. Recently, synthetic aperture radar (SAR) has emerged as a promising satellite technology capable of producing high-resolution two-dimensional measurements of wind speeds at the ocean surface, thanks to new acquisition modes and algorithmic developments. Given these new observational opportunities, we are exploring the contribution of near-core structural features, only discernible through high-resolution instruments, to cyclone dynamics. Using a simple theoretical framework and examining its consistency with SAR measurements, we demonstrate that surface winds near the core control the evolution of the cyclone wind structure. The framework developed illustrates how future measurements of ocean-atmosphere boundary layer characteristics could benefit from short- and long-term monitoring of tropical cyclones.
