This protocol is used for eDNA metabarcoding of the 18S SSU rRNA Gene (Balzano et al 2015) using Pair-End Illumina Miseq. Sequencing. As part of the Hakai Institute Ocean Observing Program, biomolecular samples have been collected weekly, from 0 m to near bottom (260 m), to genetically characterize plankton communities in the Northern Salish Sea since 2015. This protocol is developed to provide taxonomic annotations of Eukaryote Nuclear DNA.
