A daily analysis of African dust concentrations in the Mediterranean atmosphere has been made between June 1983 and December 1994 using International Satellite Cloud Climatology Project (ISCCP‐B2) archive Meteosat visible (VIS) channel images. The ISCCP‐B2 infrared (IR) images also used to determine frequencies mobilization over continent, north 30°N. Despite a large variability, climatological results show clear seasonal cycle with maximum during dry season: transport begins eastern basin...
Abstract Health and resilience of the coral holobiont depend on diverse bacterial communities often dominated by key marine symbionts Endozoicomonadaceae family. The factors controlling their distribution functional diversity remain, however, poorly known. Here, we study ecology at an ocean basin-scale sampling specimens from three genera ( Pocillopora , Porites Millepora ) 99 reefs 32 islands across Pacific Ocean. analysis 2447 metabarcoding 270 metagenomic samples reveals that each genus...
Coral reefs are among the most diverse ecosystems on Earth. They support high biodiversity of multicellular organisms that strongly rely associated microorganisms for health and nutrition. However, extent coral reef microbiome diversity its distribution at oceanic basin-scale remains to be explored. Here, we systematically sampled 3 morphotypes, 2 fish species, planktonic communities in 99 from 32 islands across Pacific Ocean, assess composition biogeography. We show a very large richness...
Coral reefs are the most diverse habitats in marine realm. Their productivity, structural complexity, and biodiversity critically depend on ecosystem services provided by corals that threatened because of climate change effects—in particular, ocean warming acidification. The coral holobiont is composed animal host, endosymbiotic dinoflagellates, associated viruses, bacteria, other microeukaryotes. In mandatory photosymbiosis with microalgae family Symbiodiniaceae its consequences evolution,...
Tropical coral reefs are among the most affected ecosystems by climate change and face increasing loss in coming decades. Effective conservation strategies that maximize ecosystem resilience must be informed accurate characterization of extant genetic diversity population structure together with an understanding adaptive potential keystone species. Here we analyzed samples from Tara Pacific Expedition (2016-2018) completed 18,000 km longitudinal transect Ocean sampling three widespread...
Over the last decade, several coral genomes have been sequenced allowing a better understanding of these symbiotic organisms threatened by climate change. Scleractinian corals are reef builders and central to ecosystems, providing habitat great diversity species.In frame Tara Pacific expedition, we assemble two genomes, Porites lobata Pocillopora cf. effusa, with vastly improved contiguity that allows us study functional organization genomes. We annotate their gene catalog report relatively...
Abstract The Tara Pacific expedition (2016–2018) sampled coral ecosystems around 32 islands in the Ocean and ocean surface waters at 249 locations, resulting collection of nearly 58 000 samples. was designed to systematically study warm-water reefs included corals, fish, plankton, seawater samples for advanced biogeochemical, molecular, imaging analysis. Here we provide a complete description sampling methodology, explain how explore access different datasets generated by expedition....
Abstract Coral reef science is a fast-growing field propelled by the need to better understand coral health and resilience devise strategies slow loss resulting from environmental stresses. Key are symbiotic interactions established within complex holobiont, i.e . multipartite assemblages comprising host organism, endosymbiotic dinoflagellates, bacteria, archaea, fungi, viruses. Tara Pacific an ambitious project built upon experience of previous Oceans expeditions, leveraging...
We used 18 years (1979–1992 and 1997–2000) of aerosol observations from TOMS satellites to monitor the inter‐annual variability summertime atmospheric dust optical thickness over both Atlantic Africa. A comparison thicknesses with ground‐based Sun‐photometer measurements shows that our long‐term data set is consistent in time space thus suitable for studying interannual decadal African transport. Our results show emissions North western Sahel are so variable one year other they control most...
Interactions between the ocean and atmosphere occur at air-sea interface through transfer of momentum, heat, gases particulate matter impact upper-ocean biology on composition radiative properties this boundary layer. The Tara Pacific expedition, launched in May 2016 aboard schooner Tara, was a 29-month exploration with dual goals to study ecology coral systems along ecological gradients Ocean assess inter-island open surface plankton neuston community structures. In addition, key...
Abstract Endogenous viral elements (EVEs) offer insight into the evolutionary histories and hosts of contemporary viruses. This study leveraged DNA metagenomics genomics to detect infer host a non-retroviral dinoflagellate-infecting +ssRNA virus (dinoRNAV) common in coral reefs. As part Tara Pacific Expedition, this surveyed 269 newly sequenced cnidarians their resident symbiotic dinoflagellates (Symbiodiniaceae), associated metabarcodes, publicly available metagenomes, revealing 178...
Heat waves are causing declines in coral reefs globally. Coral thermal responses depend on multiple, interacting drivers, such as past exposure, endosymbiont community composition, and host genotype. This makes the understanding of their relative roles adaptive and/or plastic crucial for anticipating impacts future warming. Here, we extracted DNA RNA from 102 Pocillopora colonies collected 32 sites 11 islands across Pacific Ocean to characterize host-photosymbiont fidelity investigate...

Abstract While a rich history of patchiness research has explored spatial structure in the ocean, there is no consensus over controls on biological and how physical-ecological-biogeochemical processes relate. The prevailing thought that physics structures biology, but this not been tested at basin scale with consistent situ measurements. Here we use slope relationship between variance vs to quantify ~650,000 nearly continuous ( dx ~ 200 m) measurements - representing Atlantic, Pacific,...
Between March 2023 and September 2024, the Tara Europa expedition embarked 50 international scientists to systematically deploy over 60 protocols at 188 sites along European coastline from Finland Greece. Covering waters of 19 countries, teams on board measured a suite oceanographic (bio)physical parameters recovered approximately 23,000 samples characterize mosaic coastal aquatic ecosystems way, ranging molecules organisms viruses animals. was ocean part larger initiative, TREC - Traversing...

Abstract The Tara Microplastics mission was conducted for 7 months to investigate plastic pollution along nine major rivers in Europe—Thames, Elbe, Rhine, Seine, Loire, Garonne, Ebro, Rhone, and Tiber. An extensive suite of sampling protocols applied at four five sites on each river a salinity gradient from the sea outer estuary downstream upstream first heavily populated city. Biophysicochemical parameters including salinity, temperature, irradiance, particulate matter, large small...
Abstract Telomeres are environment-sensitive regulators of health and aging. Here,we present telomere DNA length analysis two reef-building coral genera revealing that the long- short-term water thermal regime is a key driver between-colony variation across Pacific Ocean. Notably, there differences between studied genera. The lengths short-lived, more stress-sensitive Pocillopora spp. colonies were largely determined by seasonal temperature variation, whereas those long-lived,...

Coral reefs are marine biodiversity hotspots that provide a wide range of ecosystem services. They also reservoirs bioactive compounds, many which produced by microbial symbionts associated with reef invertebrate hosts. However, for the keystone species coral reefs, reef-building corals themselves, we still lack systematic assessment their microbially encoded biosynthetic potential, and thus molecular resources may be at stake due to alarming decline in cover. Here, analysed genomes...
