A look back at the DRASTIC low-carbon oceanographic cruise

, , ,

A “low-carbon” oceanographic cruise aboard an old sailing ship off the coast of Norway.

At the Arctic Circle, where the waters of the North Atlantic and the Arctic meet, LEMAR scientists from the European Institute for the Sea in Brest (IUEM) are studying silicon, an essential nutrient for marine micro-organisms such as diatoms and radiolarians. The latter are at the base of the marine food chain. They also play a key role in producing the oxygen we breathe and in sequestering atmospheric carbon.

The project aims to gain a better understanding of marine environmental changes at high latitudes and their consequences for the fate of planktonic siliceous organisms.

Scientists were the first to warn of climate change and now want to show the way to mitigate and reduce carbon emissions. The research was therefore carried out from a sailing boat. The boat’s equipment was also carbon-free: the main winch used to send the scientific equipment to a depth of 1,000 metres was powered solely by human energy, with the scientists transformed into cyclists! This low-tech ‘velotreuil’ proved its effectiveness and gave the scientists a chance to do a bit of sport. Compared with conventional oceanographic vessels, the campaign’s carbon footprint was reduced by 70 tonnes of CO2 (the annual emissions of 11 Norwegians).As the cost of the campaign was also lower, this means that the reduction in carbon emissions saved money. Indeed, the cost of CO2 abatement for the mission is estimated at around €1,000 per tonne. The 20-metre sailing boat was the LUN II, a superb wooden vessel built in Norway (around Alesund) in 1914. It is mainly used as a sailing cargo ship, under the direction of its captain Ulysse Buquen, and has been used to set up laboratories for water filtration and microscopic observations.

The scientific team was intergenerational (ranging from 29 to 58 years old), international (with researchers from Brest, British, and American universities), gender-balanced, and led by women. It consisted of 9 individuals, including several current or former members of LEMAR (links to their profiles): Aude Leynaert, Lucie Cassarino, Matthieu Civel-Mazens, Natalia Llopis-Monferrer, Nicolas Djeghri, Jean Luc Baradat, Oscar Chuberre (photographer), Ulysse Buquen (the captain), and Magnus Brask Nordfonn (sailor).

During their journey, they gave lectures at the universities of Tromsøe, Bodø, and Bergen, and met with Norwegian scientists to promote future collaboration and student exchanges.

The expedition was primarily funded by the French public sector, including the École Universitaire de Recherche Isblue, the ANR (Agence Nationale pour la Recherche), the CNRS, the Brittany region, and the LEMAR laboratory of the IUEM.


Phycotox 2023 : Annual conference GdR Phycotox – GIS Cyanobacteria 2023


This year, the GdR phycotox, co-directed by Hélène Hégaret (CNRS, LEMAR) and Philipp Hess (Ifremer-Nantes), is organizing its annual meeting jointly with the GIS Cyanobacteria, around a scientific conference that will take place face-to-face at Ifremer Nantes from May 23 to 25, 2023.


The GdR PHYCOTOX was created in 2013 to bring together actors from the scientific community specializing in toxic and harmful microalgae and their impacts on human and environmental health. It was renewed in 2018 for 5 years in order to continue the collaborative work with the aim of addressing fundamental societal issues and helping sectors affected by these phenomena (aquaculture, fisheries, tourism etc.) and risk assessors and managers


8th European Phycological Congress

, , ,

After Zagreb in 2019, we are pleased to invite you to Brest (Brittany, France) for the 8th European Phycological Congress “Scientific Opportunities for a Global Algal Revolution” on behalf of the Federation of European Phycological Societies council and the French Phycological Society. France has a long and proud tradition of phycological research and has a very diverse algal flora. Brittany is a world hotspot for seaweed diversity with about 700 species and has historically developed a flourishing macroalgal industry that still maintains its leadership in Europe. The region also hosts important research institutes dedicated to microalgae research and oceanography.

The European Phycological Congress series began in Cologne, Germany in 1996 and has since continued the tradition of bringing together phycologists from around the world every four years. Its main objective is to provide a forum for discussion of the latest scientific, technological and societal developments in phycological research. EPC8 includes plenary presentations, a series of symposia grouped into 6 themes, contributed papers and posters covering a wide range of topics such as algal diversity, ecology, genomics, cell biology, applied phycology and societal perception of algae. To encourage cross-community connections, each symposium will address micro- and macroalgae from marine, freshwater, and terrestrial ecosystems whenever possible. We look forward to welcoming you to Brest in August 2023 for EPC8!

On behalf of the organizing committees, Solène Connan and Philippe Potin

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
