Pangaea is a digital library for data from earth system research. Data sets include a metadata description with a bibliographic citation, persistently identified using a DOI. The system is open to any project or individual scientist for data archiving and publishing. The system is hosted by AWI and MARUM.

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

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.
