Giving a voice to the invisible majority of the Ocean: the marine microbiome
The marine microbiome, key to life on Earth What is a microbiome? Until recently, some researchers referred to microbiome as the living environment of microorganisms1; others, as their genome. Then, in June 2020, dozens of specialists worldwide finally published a clear definition: a microbiome is a microbial community evolving within a well-defined habitat. The term

Is it possible to highlight a change within plankton communities due to ocean eddies?
Ocean circulation Connecting 2 continents by sailing near the Roaring 40s and the Furious 50s (*1) is a true maritime adventure that requires facing raging elements: high winds, gigantic waves and very cold temperatures. These areas are also characterized by strong currents separating ocean regions with very different hydrographic properties. This illustrates the key role
Integrating the ocean into the climate regime: the Ocean & Climate Platform’s challenge
A collective watches over the Ocean The ocean is a key player in climate regulation. Unfortunately, it has long been absent from climate negotiations. In order to integrate the ocean into the climate regime, a group of civil society actors, with the support of the Intergovernmental Oceanographic Commission (IOC) of UNESCO, decided to create the

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
Plastic pollution, the solutions are circular
To find the best solutions, we need to go back to the source of the problem. The current economic model, based on the extraction of resources, their transformation and then their destruction, depletes the planet and generates mass waste. This is true regardless of the resources, whether organic or geological in origin. This impasse was

Plastic pollution in the Ocean: What are the Tara Ocean Foundation’s levers for action?
What is plastic? Plastic is not a single material. There are thousands of types, with a wide variety of visual, mechanical and technical properties. This diversity of physical properties can be explained in two ways: First by the initial diversity of plastic polymers such as polypropylene (PP), polystyrene (PS), polyvinyl chloride (PVC) or polyethylene (PET).

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

Tara-Jambio mission: studying microplastic pollution in Japan
If the Japanese coasts are known to shelter a significant biodiversity, they are also known for their high concentration of microplastics, these particles of a size between 0.3 and 5 millimeters, forming a pollution almost invisible to the eye, complex and difficult to treat. Identify and better understand the fragmentation of this plastic waste and

Why is scientific research essential in Antarctica?
Discovering the Antarctic continent 1- Geography and climate What is the surface area of Antarctica? More than 98% of this continent is covered with ice. In this area of the globe, different types of ice coexist: the ice cap and sea ice. The ice cap is a freshwater glacier (resulting from long-term accumulation of continental snow) covering an

Microbiome mission: Tara studies the Brazilian coasts
Ecosystems are rich in biodiversity off the coast of Brazil The Brazilian coasts are characterized by the presence of strong ocean currents. These currents ensure an extended mixing of the Amazon waters in the Atlantic Ocean that influences marine life. The first stage of the mission was to study the Amazon plume. The Amazon plume: 2
