The North Pacific Eukaryotic Gene Catalog: Raw assemblies from Gradients 1, 2 and 3

Description

The North Pacific Subtropical Gyre is bordered on its northern side by a region known as the North Pacific Transition Zone; a latitudinal band of strong physical, chemical, and biological gradients and high productivity where warm, nutrient-deplete water from the subtropical gyre mixes with cold, nutrient-rich water from the north. The North Pacific Eukaryotic Gene Catalog consolidates eukaryotic metatranscriptome data from three latitudinal transects of the transition zone and one cruise in the subtropical gyre. Metatranscriptomes were gathered from latitudinally-resolved surface samples, and diel-resolved temporal studies, with samples taken in triplicate or duplicate and collected on 0.2-100 μm, 0.2-3 μm, and 3 μm-100 or 200 μm size fractions. These metatranscriptome data were de novo assembled into 175 independent assemblies, totalling 182 million clustered transcript contigs. Assemblies were annotated by taxonomy and function and enumerated by short read alignment. This catalog provides  assembled environmental contigs, their translated peptide sequences, taxonomic and functional annotations and read counts with the aim of facilitating continued discoveries about the molecular ecology of microbial eukaryotes in the North Pacific.
