How does climate change disrupt ocean currents and the distribution of the marine microbiome?

What impact does pollution and particularly microplastics have on the marine microbiome?

How does the land fertilise the ocean?

For nearly two years the laboratory-ship Tara will travel 70,000 kilometres in the South Atlantic, along the coasts of South America, as far as Antarctica. Devised by Fondation Tara Océan as part of the European AtlantECO programme and with scientific partners including the CNRS, CEA and EMBL, this mission involves 42 research structures across the world in studying the benefits of the ocean microbiome and its interactions with the climate and pollution.

This invisible life will no longer hold any secrets

very litre of sea water contains between 10 and 100 billion microorganisms.
Their size ranges from 0.01 micrometres to 1 cm. That’s the same difference in scale as between an ant and a brontosaurus.

Colomban de Vargas, researcher CNRS/Sorbonne:

Unlike previous Tara missions that carried out uniform sampling wherever the ship went, to reveal “What’s there?”, here, we are going to adapt the protocols during the mission to find out “How does it work?”. »

What is the microbiome?

Tara mission Microbiomes

New challenges to be taken up


Understanding more deeply the great mechanisms linking microbiomes and climate.


Raising awareness

Inviting the public and school classes on board to increase understanding of the ocean and the challenges of protecting it. 23 stopovers are planned where scientific teams will train local researchers on the know-how and techniques of ocean studies.



Two educational operations will be offered to schools. In Tara’s wake, so that students can interact live by video conference with members of the crew and Echos d’Escale, to approach the challenges of sustainable development across the world.

The team

All aboard the schooner

Mission Microbiomes is part of the European AtlantECO project, financed by the European Commission, that brings together 36 scientific institutions in Europe, Brazil and South Africa and involves 15 scientists on the ship itself. This international scientific collaboration is intended to develop a deeper understanding of the challenges linked to the Atlantic Ocean. AtlantECO will roam the Atlantic Ocean with six main expeditions, two of which will study the coasts of Brazil.
