Occurrence of Eukaryotes in the size fraction >680 micrometres, collected worldwide during the Tara Oceans expedition (2009-2013) using a Régent net and analysed on a ZooScan imaging platform

The Tara Oceans project sampled contrasting ecosystems of the world oceans during a three-year expedition (2009-2013), collecting environmental data and plankton, from viruses to metazoans, on board the 36-metre Tara Schooner. It surveyed 210 ecosystems in 20 biogeographic provinces, collecting over 35,000 samples of seawater and plankton. Samples were later analysed using modern sequencing and state-of-the-art imaging technologies.
