Here we present a dataset of 76 microbial metagenomes of the picoplankton size fraction (0.2-3.0 μm) collected in 11 stations along the Malaspina Expedition circumnavigation (http://www.expedicionmalaspina.es; Duarte 2015) that cover vertical profiles sampled at 7 depths, from the surface to 4,000 m deep (or the sea floor in shallower waters), plus 5 additional metagenomes. This Malaspina Microbial Vertical Profiles metagenomes (MProfile) dataset produced 1.66 Tbp of raw DNA sequences. Six L seawater samples were collected and filtered through a 200 and a 20 μm mesh to remove large plankton, the prokarotic free-living size fraction (0.2 to 3.0 µm) was recovered in each sample by pumping water serially through 47-mm polycarbonate membrane filters of 3.0 μm and 0.22 μm pore sizes with a peristaltic pump. DNA was extracted using a standard phenol-chloroform protocol and was sequenced at the National Center for Genomic Analsis (CNAG-CRG. Barcelona, Spain; www.cnag.es), funded by project MALASPINOMICS (CTM2011-15461-E, led by Carlos M Duarte) on the Illumina HiSeq2000 sequencing platform utilizing a TruSeq paired-end cluster kit, v3, following a 2x100 indexed run recipe.
