Amplicon sequences from seawater sample
Seawater samples were filtered using 0.22 um Sterivex filters to capture environmental DNA (eDNA). Barcodes in these samples and their corresponding negative controls were amplified using primers designed for this study that target nuclear, eukaryotic 28S in anthozoan corals and primers from Everett & Park (2018) that target mitochondrial MutS in octocorals.
