Description: The Tara Oceans Expedition (2009-2013) sampled the world oceans on board a 36 m long schooner, collecting environmental data and organisms from viruses to planktonic metazoans for later analyses using modern sequencing and state-of-the-art imaging technologies. Tara Oceans Data are particularly suited to study the genetic, morphological and functional diversity of plankton. The present data set includes text files, one for each station, that contain the annual cycle of key parameters estimated daily from remote sensing products at a spatial resolution of 9km centered on the sampling location. File names correspond to the station identifier (TARA_station#). A description of all parameters is provided in a README file.

Tara Oceans Data are particularly suited to study the genetic, morphological and functional diversity of plankton. The present data set includes text files, one for each station, that contain the annual cycle of key parameters estimated daily from remote sensing products at a spatial resolution of 100km centered on the sampling location. File names correspond to the station identifier (TARA_station#). A description of all parameters is provided in a README file.

Description: The present data set provides a tab separated text file compressed in a zip archive. The file includes metadata for each TaraOceans V9 rDNA OTU including the following fields: md5sum = identifier of the representative (most abundant) sequence of the swarm; cid = identifier of the OTU; totab = total abundance of barcodes in this OTU; TARA_xxx = number of occurrences of barcodes in this OTU in each of the 334 samples;rtotab = total abundance of the representative barcode; pid = percentage identity of the representative barcode to the closest reference sequence from V9_PR2; lineage = taxonomic path assigned to the representative barcode ; refs = best hit reference sequence(s) with respect to the representative barcode ; taxogroup = high-taxonomic level assignation of the representative barcode. The file also includes three categories of functional annotations: (1) Chloroplast: yes, presence of permanent chloroplast; no, absence of permanent chloroplast ; NA, undetermined. (2) Symbiont (small partner): parasite, the species is a parasite; commensal, the species is a commensal; mutualist, the species is a mutualist symbiont, most often a microalgal taxon involved in photosymbiosis; no the species is not involved in a symbiosis as small partner; NA, undetermined. (3) Symbiont (host): photo, the host species relies on a mutualistic microalgal photosymbiont to survive (obligatory photosymbiosis); photo_falc, same as photo, but facultative relationship; photo_klep, the host species maintains chloroplasts from microalgal prey(s) to survive; photo_klep_falc, same as photo_klep, but facultative; Nfix, the host species must interact with a mutualistic symbiont providing N2 fixation to survive; Nfix_falc, same as Nfix, but facultative; no, the species is not involved in any mutualistic symbioses; NA, undetermined.

Description: The Tara Oceans Expedition (2009-2013) sampled the world oceans on board a 36 m long schooner, collecting environmental data and organisms from viruses to planktonic metazoans for later analyses using modern sequencing and state-of-the-art imaging technologies. Tara Oceans Data are particularly suited to study the genetic, morphological and functional diversity of plankton. The present data set provides environmental context to all samples from the Tara Oceans Expedition (2009-2013), about pigment concentrations in the targeted environmental feature. Pigment concentrations were measured by High Pressure Liquid Chromatography (HPLC) on water samples. For each parameter we provide six statistics about all observations that are considered adequate to characterise the targeted environmental feature: number of observations, minimum, first quartile (25 percentile), median, third quartile (75 percentile), and maximum values. Observations were considered adequate if they met the following criteria: 〈100 km from the sampling location, 〈2 days from the sampling date/time, and within 10 m of the sampling depth. We also provide the computed distance and date/time lags that were assessed against these criteria. No environmental context is provided when one of these criteria was not met.

Tara Oceans Data are particularly suited to study the genetic, morphological and functional diversity of plankton. The present data set provides methodological context about the sampling and on-board-preparation of samples during the Tara Oceans Expedition (2009-2013). For each sample, we provide details about the standard protocols (i.e. Sample Method) as well as deviations from these protocols (i.e. Sample Comment). We also provide URLs to related data, sampling logsheets, campaign summary reports, oceanographic reports, and step-by-step protocols.

Tara Oceans Data are particularly suited to study the genetic, morphological and functional diversity of plankton. The present data set provides environmental context to all samples from the Tara Oceans Expedition (2009-2013), about carbonate chemistry in the targeted environmental feature. Total alkalinity (AT) and total carbon (CT) were measured potentiometrically (Edmond 1970), and other carbonate chemistry parameters (pH on total scale, CO2, pCO2, fCO2, HCO3, CO3, OmegaAragonite and OmegaCalcite) were calculated using seacarb (Nisumaa et al. 2010). For each parameter we provide six statistics about all observations that are considered adequate to characterise the targeted environmental feature: number of observations, minimum, first quartile (25 percentile), median, third quartile (75 percentile), and maximum values. Observations were considered adequate if they met the following criteria: 〈100 km from the sampling location, 〈2 days from the sampling date/time, and within 10 m of the sampling depth. We also provide the computed distance and date/time lags that were assessed against these criteria. No environmental context is provided when one of these criteria was not met.

Tara Oceans Data are particularly suited to study the genetic, morphological and functional diversity of plankton. The present data set provides environmental context to all samples from the Tara Oceans Expedition (2009-2013), about nutrient concentrations in the targeted environmental feature. Concentrations of nitrite, nitrite+nitrate, phosphate and silicate were determined by ... methods. For each parameter we provide six statistics about all observations that are considered adequate to characterise the targeted environmental feature: number of observations, minimum, first quartile (25 percentile), median, third quartile (75 percentile), and maximum values.
