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

Tara expeditions (2009-2013) 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, multinet trawls allowed to sample the vertical distribution of plankton; this is the content of this dataset. Using a 300µm mesh net, it cover organisms from 300µm to ~3cm.

Tara远征队（2009-2013年）依据标准化协议对全球海洋进行了采样，特别致力于在大范围尺寸内对浮游生物多样性进行采样，结合水样采集和网拖的方式进行。通过元条形码和宏基因组学技术对浮游生物基因组多样性进行探索的努力，已导致广为人知的学术论文发表，并使Tara远征队声名鹊起。尽管在成像方面也投入了类似的广泛努力，但相关数据集尚未公开。在有限的站点中，除了常规的5μm至~5cm的Tara采样策略外，多网拖捕技术得以实现对浮游生物垂直分布的采样；这正是本数据集的内容。采用300µm网目的网具，该数据集涵盖了从300µm至~3cm的各类生物。
