The voyage will cover 70,000 kilometers in the South Atlantic, along the African and South-American coasts and on to Antarctica. The expedition's objective is to explore the oceanic microbiome and determine its future in the current era of climate change.Conceived by the Tara Ocean Foundation, the CNRS, the CEA and the EMBL¹, the mission will involve close to 200 scientists across 42 research structures—including Genoscope (CEA-Jacob).

The method reconstructs transcriptomes of eukaryotes from environmental sequencing data, thus enabling access to the genetic organization of these organisms, even those that have not yet been described, to study their functional potential. Also, with the method, interspecies associations can be identified across samples taken in different oceanic provinces. The novel approach is a door to the environmental context and biological functions of numerous species of ecological interest. The team's work was published in Genome Research.
