Saupe qui peut : a film to be better in his plate


Our plate is the reflection of our links to biodiversity. Short circuits, sustainable fishing, forgotten species to be rediscovered: there are many ways to eat with respect for life. This is the purpose of the film "Saupe qui peut! This documentary, produced by the association Bouillabaisse Turfu and the Parc national des Calanques, gives us tracks to feel better in our plate. This documentary brings together the chef Christian Qui, founder of Bouillabaisse Turfu, Sandrine Ruitton, a scientist from the Mediterranean Institute of Oceanology (MIO) and Achraf Stifine, a fisherman from Marseilles. By crossing the views between cooking, artisanal fishing and marine biodiversity, it encourages consumers to cook a forgotten or even unloved species: the saupe, a herbivorous fish rather abundant in the Mediterranean. After a preview screening at the World Conservation Congress last September, the public release of this film in 2022 marks the National Park's entry into the "International Year of Artisanal Fisheries and Aquaculture" decreed by the UN.

Marine biodiversity: how to preserve the Posidonia meadow ?


In the Mediterranean, a large part of the biodiversity develops on the sea bed between 0 and 50 meters. It is at this depth that we find the Posidonia meadow, a flowering plant endemic to this sea, a real nursery for the Mediterranean marine world.

The fire on board a cargo ship that has been sinking for 13 days off the coast of Sri Lanka's capital was extinguished on Tuesday 1 June thanks to an international operation. But the ship is now sinking, with fuel oil, nitric acid, and millions of plastic pellets on board that have already started to spread. As Damien Sous (from 2'10"), from the MIO-University of Toulon, explains, the most direct impact remains fuel oil and nitric acid !

NOTION Project: These small marine creatures that could save our oceans


The ocean contributes to climate regulation. Thus, in the face of global warming and ocean acidification, what is the role of diazotrophic plankton in this function? Who are their allies? What are the consequences of climate change on these micro-organisms and, more importantly, on the biological activity and productivity of the oceans?

Tonga mission - In search of Pacific submarine volcanoes


One year ago, the Atalante, a french oceanographic vessel, sailed towards the Pacific in search of shallow submarine volcanoes to understand and anticipate the consequences of fluid emanations on marine life and climate. The expedition, led by Sophie Bonnet (MIO IRD) and Cécile Guieu (LOV CNRS), is analyzing and studying the consequences of the contribution of trace elements from shallow hydrotermal sources to determine their potential impact on marine productivity and the biological carbon pump.

An air purifier installed at the Lycée Français Alexandre Yersin in Hanoi to study

the impact of fine particle pollution on marine processes !


Presentation of Xavier Mari - MIO-IRD


In order to be able to carry out experiments to determine the impact of fine particle pollution on marine processes, we acquired the Aufero air purifier developed by ENS Clean Air. Technically, this air purifier works by positive ionisation. The fine particles, which are drawn in at a flow rate of 7500 m3/h, are ionised at the inlet of the air purifier and then collected on a negatively charged metal plate, thus purifying the exhaust air. This filterless air purification system (i.e. it can operate continuously) is capable of removing particles from 10 nanometres to 30 micrometres in the ambient air. This equipment, generally used to purify the air in very large polluted spaces, such as car parks, has been acquired with IRD funding as part of the SOOT-SEA initiative in order to collect large quantities of fine particles; these are recovered by scraping the collection plate.

Initially planned to be installed outdoors in Hanoi, we felt it would have been a pity if no one had taken advantage of this purified air. So, in agreement with the French Embassy in Vietnam and the French Lycée Alexandre Yersin, we opted for an installation in the gymnasium of the latter.

Indeed, given the deterioration of the air quality in Hanoi, the school had to implement a protocol to protect the students, including the elimination of outdoor classes when the PM2.5 concentration exceeds 55 µg/m3 (AQI>150); the classrooms benefiting from a general air purification system. The gymnasium to which the students could have gone when air quality reached critical levels was not equipped with an air purification system.

The SOOT-SEA air purifier was therefore installed in the gymnasium. It operates continuously and provides both cleaner air in the gym and a continuous collection of particulate aerosols present in Hanoi. We collect about 200g of fine particles every 3 months.

The MIO coordinator of a European research project on microplastics led by the University of Toulon


The Interreg Marittimo SPlasH project! (Stop alle Plastiche in H2O) project aims to analyze the presence, origin and dynamics of microplastics in the ports of the Tyrrhenian Sea (Genoa, Olbia, Toulon) as well as to determine their potential role as a vector of contaminants in coastal areas. The data collected by the MIO laboratory of the University of Toulon and its partners will provide the international community with elements to better understand the link between geography and quantity/nature of microplastics as well as the risk associated with their presence.

In search of the new Sargasso Sea


From June 19 to July 13, 2017, a scientific expedition conducted on board ANTEA, a ship of the French Oceanographic Fleet, enabled a team of researchers to carry out a significant sampling of the fauna and flora associated with "sargasso rafts". These pelagic brown algae found in the tropical Atlantic have been stranded on the Atlantic coast since 2011, due to ocean circulation. They are responsible for significant environmental, health and economic problems, particularly in the Caribbean and French Guiana.


The OUTPACE cruise in video!


The OUTPACE oceanographic cruise took place from February 18 to April 3, 2015 in the Pacific Ocean aboard the N/O L'Atalante. The project aimed to provide a zonal description of biogeochemistry and biological diversity in the tropical southwest Pacific and to produce a detailed study of organic production and its future in three contrasting sites, with particular attention to production supported by nitrogen fixation and carbon export by the biological pump.
