Mesophotic and Deep Benthic Communities (MDBC) eDNA metabarcoding: PS2309, R/V Point Sur, September 2022
Data from environmental DNA (eDNA) samples filtered from seawater collected in the Gulf of America during expedition PS2309 on the R/V Point Sur in September 2022. Samples were collected at depths throughout the water column. Each eDNA sample was amplified using four primer sets: MiFish 12S rRNA marker targeting ray-finned fishes; 28S rRNA marker targeting corals and other cnidarians; and 18S rRNA and CO1 mtDNA general markers for eukaryotic plankton, protists, and other invertebrates. Sequences were then processed bioinformatically to infer amplicon sequence variants (ASVs) and assign taxonomic identifications from the WoRMs database. This data was collected as part of the Habitat Assessment and Evaluation Project, one of four projects implemented to restore Mesophotic and Deep Benthic Communities (MDBC) injured by the Deepwater Horizon (DWH) oil spill.
