Reinforcing scientific expertise in understanding planktonic ecosystems through collaboration among young researchers

The Ocean Plankton, Climate, and Development project (2016-2022), in partnership with the French facility for Global Environment (FFEM*), enabled the Foundation and its partner laboratories to establish a program for training and expertise exchange aimed at understanding planktonic ecosystems. Young researchers from the Global South (Argentina, Brazil, Chile, Senegal, and Togo), with diverse expertise (geneticist,

Impact of anthropic activities on biodiversity along the shoreline: development of coastal occupation

What is the shoreline? According to Michel Desse, professor of human geography of coastal areas at the University of Nantes, the shoreline is an interface zone between land and sea/ocean that fluctuates depending on the day (under the influence of tides, for example), season and climate-related events, such as marine submersion. In some places, the

[Tara Océans] Discovery of new viruses in the ocean: Mirusviruses

Viruses infect plankton in the ocean Scientists characterized a new group of DNA viruses which they named «mirusviruses». “Mirus“ is a Latin word which means strange, or even surprising. The name reflects the unusual evolutionary traits of these viruses which have very complex genomes, with hundreds of genes and many functions which are currently completely


[Tara Pacific] First results of an extraordinary expedition

Five years of analysis: the time for scientific research Thousands of samples to study While the long time between the end of the expedition and the publication of the results may seem surprising, it is nevertheless usual for this type of scientific work. There are two reasons for this. Firstly, the quantity of data generated

Tara Pacific: Towards a new understanding of coral reefs, sentinels of climate change

What is coral? Coral: animal, vegetable, mineral? When observing a coral on a reef, we do not observe an animal, nor an alga, nor a rock, but all three combined. Indeed, a coral is a colony of animals fixed on their limestone skeleton, sheltering in its tissues micro-algae which give them their bright colors. These

Part 3 of the Microbiome mission: the schooner Tara samples the West African coast for 5 months

An ambitious scientific program in West Africa For 5 months, the schooner will stopover in 7 African countries: South Africa, Namibia, Angola, Democratic Republic of Congo, Republic of Congo, Gambia and Senegal. During this presence along the African coasts, the Tara Ocean Foundation and associated research institutes will delve into 3 major scientific projects: The

5,500 new RNA virus species discovered in the Ocean using samples collected during Tara Oceans mission

Discovering the RNA virosphere The ocean was once thought to be a vast desert in terms of viruses. Today, scientists are turning to the multitudes we now know inhabit the world’s seas to unravel mysteries of their biology, evolution, and function. While viruses are synonymous with disease, they also infect smaller organisms that run the
