Tara Oceans: discovery of over 100 million genes from the marine world

The Tara Oceans expedition (2009-2013) has enabled the collection of plankton samples in all of the world's oceans on board the schooner Tara, and the creation of catalogues of species and genes on a scale never before undertaken. Continuing the analysis and exploitation of the biggest database compiled on the planktonic ecosystem, the teams from the CEA, CNRS (French National Centre for Scientific Research), EMBL (European Molecular Biology Laboratory) and the French graduate school ENS, among others , have just reached a new milestone by analysing the expression of over 100 million genes belonging to complex organisms, from microscopic algae to small planktonic animals.

Interdisciplinary postdoctoral training offered at Tara Oceans laboratories

Open to applicants from Argentina, Brazil and Chile, this call will initially provide funding for four positions over 2.5 years, with additional opportunities if applicants are able to secure their own funding or the availability of matching funds from the country of origin or the host laboratory. Six interconnected proposed projects aim at using the power of the complete Tara Oceans dataset to unravel the architecture of plankton organismal and metabolic networks across our changing oceans, and model their dynamics across space and time, and in comparison to fish population dynamics. Each postdoc will work with a main adviser, but should collaborate with at least two laboratories of the consortium having complementary expertise in different disciplines.

New Plankton Chronicles website available

The Plankton Chronicles Project is a short documentary series combining art and science, revealing the beauty and diversity of organisms adrift in the currents. The project was started in the context of the Tara Oceans Expedition and the Observatoire Oceanologique de Villefranche-sur-Mer (OOV).

Major first results published in special issue of Science 22 May 2015

Using the research vessel Tara, the Tara Oceans expedition sampled plankton ecosystems around the world and collected associated oceanographic data. The wet part of the expedition was accompanied by an integrative analysis on land, incorporating DNA sequencing and bioinformatics, microscopic imaging, and network analysis.
