eDNA Sampling of Deep-Sea Fish Assemblages, Gascoyne Marine Park, Western Australia (2022)

eDNA samples were successfully obtained from deep-tow camera OCD (open–close device) single deployments at 23 sites (n = 23), where each site represented one discrete depth, but sites ranged across several water depths categorized as continental shelf (0–200 m; n = 6), shelf break to mid-slope (200–1000 m; n = 5), and mid-slope to abyss (1000–4000 m; n = 12). The deep- tow camera OCD eDNA transects were paired to trawl sampling at the same depth and sites conducted as close as possible to the line and length of the OCD transects.

The data has been acquired on the following RV Investigator voyage IN2022_V05 with links to additional metadata, datasets, events, deployments, publications etc.
