Jellyfish, plankton and POM SI and FA composition data, Quadra Island BC, 2019

We measured stable isotope (SI) and fatty acid (FA) profiles of particulate organic matter (POM), plankton size classes, and gelatinous zooplankton collected from Quadra Island, a coastal site in British Columbia, Canada, in July and September 2019. Gelatinous zooplankton comprised 152 Aurelia labiata collected across both months (bell diameters = 19 - 225 mm), and 2 Aequorea victoria and approximately 30 Pleurobrachia bachei collected in July for comparison.
