| Abstract | To monitor marine invasive species distribution and broad taxonomic diversity in the subtidal fauna and flora of the DFO Maritimes region, metabarcoding of eDNA samples was performed at a total of 49 sites between 2021-2022. For each site, three 1-L amber bottles of seawater collected from ~1m above the benthos at each site was filtered with Sterivex 0.22-µm filters prior to DNA extraction with a Qiagen DNEasy Power Water Kit and sequencing with an Illumina NovaSeqtm6000 instrument (primers are included in metadata). Raw paired-end reads were merged with NGmerge v0.3 and denoised with DnoisE v1.4.1 (DnoisE settings are included in the metadata). Singletons were removed and remaining sequences were assigned to species-level by BLAST against a local copy of the nr/nt database (downloaded Nov 2023). | ||||||||||||
