Pelagic microbes of the South Pacific from 2017 occupation of the GO-SHIP P18 line

16S rRNA, 18S rRNA and metagenomic sequencing of pelagic microbes collected during the 2017 occupation of the GO-SHIP P18 line in the South Pacific.BioSample names are formatted as follows:[GOSHIP-P18]_[station number]_[CTD cast number]_[niskin bottle number]_[molecular sample number][L for large filtration size class (> 5 um) or S for small filtration size class (0.22-5um)]_[collection depth in meters]For example: GOSHIP-P18_121_1_22_11L_69m is station 121, cast 1, niskin 22, molecular sample 11, large size class, collected from 69 m deep
