Mission Microbiomes CEODOS Chile Expedition Metagenomic Dataset
Marine prokaryotic plankton are fundamental components of global biogeochemical cycles, including oxygen and carbon production, and play critical roles in sustaining marine food webs. Chile's extensive coastline, characterized by diverse environmental gradients such as the Humboldt Currents System, the prominent Oxygen Minimum Zone (OMZ) and one of the world's largest fjord systems in Patagonia, represents an exceptional natural laboratory to study microbial diversity and function. Building on foundational research carried out by the Tara Oceans global expedition, the Mission Microbiomes CEODOS Chile expedition provides the first comprehensive multi-omics prokaryotic data set covering these unique ecosystems along the Chilean coast during austral summer-fall conditions (February to May). Here we present an extensive, open-access data set comprising 159 high-quality (HQ) metagenomes of the prokaryotic fraction, accompanied by robust environmental contextual data. Samples were collected from surface, epipelagic, and mesopelagic layers at 34 stations, covering critical biogeochemical features such as OMZ, upwelling zones, Patagonian fjords, and diverse coastal ecosystems. The data sets include raw reads from prokaryotes(bacteria and archaea) along with key bioinformatic analyses such as MAGs, mOTUs abundances, Gene Catalog and Gene Functional Annotation, offering a valuable baseline for understanding microbial biodiversity and functional dynamics in the South Pacific Ocean.
