IN2022_V09: Environmental DNA Data from Gascoyne Marine Park Voyage

Australian Ocean Data Network provides environmental DNA (eDNA) data collected during the RV Investigator voyage IN2022_V09. The voyage, titled 'Valuing Australia’s new Gascoyne Marine Park,' took place between November 19 and December 19, 2022, departing from and returning to Fremantle. The study compared three eDNA processing methods and validated fish detections against trawl survey data and the regional species pool.

Use Cases

• Compare eDNA sampling methodologies based on the three processing methods described: filtering OCD water, extracting eDNA from sponge pieces, and filtering sponge rinse water.
• Validate eDNA metabarcoding results for fish species against traditional survey data, as the dataset includes comparisons with bottom trawl surveys.
• Assess marine biodiversity in the Gascoyne Marine Park region using integrated eDNA samples collected over deep-water transects.

Strengths

• Data collection is tied to a specific research voyage (IN2022_V09) with a defined time range from November 19 to December 19, 2022.
• Includes methodological validation by comparing eDNA detections with independent bottom trawl survey data and a known regional species pool.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for large-scale analyses.
