Dataset

Occurrence of Eukaryotes in the size fraction >300 micrometres, collected worldwide during the Tara Oceans expedition (2009-2013) using a Bongo net and analysed on a ZooScan imaging platform

Tara expeditions sampled the world’s oceans with standardized protocols, putting an exceptional effort into sampling plankton diversity across a large size range, using a combination of water samples and net tows. The efforts to explore the genomic diversity of plankton, through metabarcoding and metagenomics, have led to well publicized papers and have made the renown of Tara. While a similar extensive effort has been put on imaging, the datasets are not public yet. In a limited number of stations, in addition to the usual 5μm -> ~5cm Tara sampling strategy, Bongo net samples were taken during the day and during the night, at the same station; this is the content of this dataset. Using a 300µm mesh net, it cover organisms from 300µm to ~3cm
