Maéva GESSON Winner of a grant from the Fondation de la Mer

, ,

The Fondation de la Mer was created in 2015 in order to support various actors in the protection of the Ocean. It conducts programmes to protect marine biodiversity and combat pollution at sea, encourages research and innovation, and aims to inform and raise awareness among the general public. The Fondation de la Mer scholarship supports, in particular, PhD students enrolled in a French-speaking doctoral school each year by providing them with €5000 in material aid, and this year it was awarded to Maéva GESSON, a doctoral student at LEMAR.

Maéva is part of the Chibido team at LEMAR, supervised by Brivaëla Moriceau and Frédéric Le Moigne. Her thesis was funded by the France Canada Research Fund and is entitled “Mechanisms of marine snow fragmentation in the mesopelagic zone of the ocean: implication on CO2 sequestration by the biological carbon pump“.

In practice, marine snow forms naturally at the ocean surface by the aggregation of organic carbon-rich particles derived mainly from phytoplankton. These aggregates sink into the water column and create a flow of carbon to the depths, providing a food source for deep-sea organisms and sequestering carbon for thousands or even millions of years on the ocean floor. However, only a few percent of this marine snow eventually reaches the abyss, and half of this can be explained by the fragmentation of the aggregates between 100 and 1000m depth. Maéva’s thesis work aims to estimate whether fragmentation phenomena induced by oceanic turbulence or resulting from the movement of zooplankton could be responsible for this fragmentation, and if so, in what proportions. She is particularly interested in the adhesive molecules contained in the aggregates in order to assess whether these determine the fragility of the marine snow.

The grant money will be used to partially fund the design of new rolling tables, which are necessary tools for the formation and study of marine snow in the laboratory. Designed and produced by the UBO Open Factory, these will allow temporal monitoring of the number, morphology and fall rate of aggregates by imaging. They will also be adapted to missions at sea, such as the APERO campaign in which Maéva will participate this summer. The plans and assembly instructions will be distributed to the whole community in open access at the end of the project.

Paddle project Final Conference

, , ,

Started in 2017, the European Paddle programme, an interdisciplinary project on marine spatial planning and coordinated by Marie Bonnin (LEMAR), is holding its final conference in Brest (IUEM / PNBI) from 15 to 17 March.

During these three days, participants of several nationalities will address different themes related to marine spatial planning in the tropics, ranging from artisanal fisheries to social and cultural dimensions, including various topics such as decision support tools or marine protected areas.

The presence of researchers from different countries and disciplines is an opportunity to review marine spatial planning development projects along the coasts of the tropical Atlantic. In addition, marine spatial planning actors such as the Regional Coastal and Marine Partnership (RPMP) and the Abidjan Convention are associated with this event and represented at the conference. The different sessions allow participants to have an overview of the different sectors of activity and types of research concerned by this growing theme.

This conference is also an opportunity for all the partners to take stock of their exchanges after a 6-year project, rich in scientific and human encounters. An exhibition of photographs and videos made during the project is also proposed to the participants.

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
