Abstract
A unique collection of oceanic samples was gathered by the Tara Oceans
expeditions (2009–2013), targeting plankton organisms ranging from viruses to
metazoans, and providing rich environmental context measurements. Thanks to recent advances in
the field of genomics, extensive sequencing has been performed for a deep genomic analysis of
this huge collection of samples. A strategy based on different approaches, such as
metabarcoding, metagenomics, single-cell genomics and metatranscriptomics, has been chosen for
analysis of size-fractionated plankton communities. Here, we provide detailed procedures
applied for genomic data generation, from nucleic acids extraction to sequence production, and
we describe registries of genomics datasets available at the European Nucleotide Archive (ENA,
www.ebi.ac.uk/ena). The association of these metadata to the experimental
procedures applied for their generation will help the scientific community to access these data
and facilitate their analysis. This paper complements other efforts to provide a full
description of experiments and open science resources generated from the Tara
Oceans project, further extending their value for the study of the world’s planktonic
ecosystems.
