Summary To obtain a proxy for the stress level of collected corals, we checked for previous occurrences of bleaching events at sampled reef sites by matching island GPS coordinates to the Reef Check dataset (reefcheck.org) obtained from Sully et al (2019). For each Tara Pacific island coordinate, we determined the Reef Check site that was...

The tables in this dataset associate metabarcoding sequencing files generated by Genoscope (i.e. fastq.gz files with informative filename structures; with sequencing file pairs associated to unique 'readset' identifiers; housed on their FTP server at www.genoscope.cns.fr/sadc/tarapacific/METABARCODING; with the 'METAB' sequence strategy...

Abstract Endogenous viral elements (EVEs) offer insight into the evolutionary histories and hosts of contemporary viruses. This study leveraged DNA metagenomics and genomics to detect and infer the host of a non-retroviral dinoflagellate-infecting +ssRNA virus (dinoRNAV) common in coral reefs. As part of the Tara Pacific Expedition, this study...

With climate projections questioning the future survival of stony corals and their dominance as tropical reef builders, it is critical to understand the adaptive capacity of corals to ongoing climate change. Biological mediation of the carbonate chemistry of the coral calcifying fluid is a fundamental component for assessing the response of...

Abstract Tropical coral reefs are among the most affected ecosystems by climate change and face increasing loss in the coming decades. Effective conservation strategies that maximize ecosystem resilience must be informed by the accurate characterization of extant genetic diversity and population structure together with an understanding of the...

This data is the result of the primary analysis of the 16S rRNA gene sequencing data collected from all islands as part of the Tara Pacific expedition. The analysis was conducted using cutadapt/snakemake/dada2 and usearch. A full README is contained within the data upload.

Coral reefs are severely threatened by global and local environmental changes. However, susceptibility to perturbations and subsequent mortality varies among coral species. In this study, we tested the contribution of genetic and environmental conditions to coral's phenotypic response in Pocillopora spp. and Porites spp. sampled together at a...

Abstract Health and resilience of the coral holobiont depend on diverse bacterial communities often dominated by key marine symbionts of the Endozoicomonadaceae family. The factors controlling their distribution and their functional diversity remain, however, poorly known. Here, we study the ecology of Endozoicomonadaceae at an ocean...

This data is the result of the primary analysis of the Symbiodiniaceae ITS2 rDNA gene sequencing data collected from all islands as part of the Tara Pacific expedition.The analysis was conducted using SymPortal. A full README is contained within the data upload.

This data is the result of the primary analysis of the V9 18S rDNA metabarcoding sequencing data from the Tara Pacific expedition. The analysis was conducted using cutadapt, vsearch, swarm and lulu. Please refer to the readme file for more details.

PHOTO dataset (in situ photos) and the colony morphometric analysis using in situ photographs of two scleractinian corals and one hydrozoan coral taken during the TARA Pacific Expedition: Pocillopra spp., Porites spp. and Millepora spp. respectively.

This dataset contains 4 tables and 3 sets of figures related to the primary analysis of the 18S metabarcoding sequencing output. This dataset is only concerned with the identity of the coral host (i.e. not additional protist diversity). The samples included in this dataset have a 'sample-material_label' value of 'CORAL' and...

Heat waves are causing declines in coral reefs globally. Coral thermal responses depend on multiple, interacting drivers, such as past thermal exposure, endosymbiont community composition, and host genotype. This makes the understanding of their relative roles in adaptive and/or plastic responses crucial for anticipating impacts of future...

Abstract Telomeres are environment-sensitive regulators of health and aging. Here,we present telomere DNA length analysis of two reef-building coral genera revealing that the long- and short-term water thermal regime is a key driver of between-colony variation across the Pacific Ocean. Notably, there are differences between the two studied...

Coral reef science is a fast-growing field propelled by the need to better understand coral health and resilience to devise strategies to slow reef loss resulting from environmental stresses. Key to coral resilience are the symbiotic interactions established within a complex holobiont, i.e. the multipartite assemblages comprising the host coral...

Interactions between the ocean and the atmosphere occur at the air-sea interface through the transfer of momentum, heat, gases and particulate matter, and through the impact of the upper-ocean biology on the composition and radiative properties of this boundary layer. The Tara Pacific expedition, launched in May 2016 aboard the schooner Tara,...

the Tara Pacific expedition (2016-2018) sampled coral ecosystems around 32 islands in the Pacific Ocean and the ocean surface waters at 249 locations, resulting in the collection of nearly 58 000 samples. The expedition was designed to systematically study warm-water coral reefs and included the collection of corals, fish, plankton, and...

Coral reefs are the most diverse habitats in the marine realm. Their productivity, structural complexity, and biodiversity critically depend on ecosystem services provided by corals that are threatened because of climate change effects—in particular, ocean warming and acidification. The coral holobiont is composed of the coral animal host,...
