IN2022_V09: Environmental DNA Data from Gascoyne Marine Park Voyage

Environmental DNA (eDNA) samples collected aboard the RV Investigator during a 30-day voyage in late 2022. The voyage, titled 'Valuing Australia’s new Gascoyne Marine Park,' departed from and returned to Fremantle. Data likely contains eDNA detections from three processing methods, compared with trawl survey data and a regional species pool to validate fish identifications.

Use Cases

• Compare eDNA sampling methodologies based on the three processing methods described (filtering OCD water, extracting from sponge pieces, filtering sponge rinse water).
• Validate eDNA-based species detection against traditional survey data based on the comparison with bottom trawl surveys mentioned.
• Assess marine biodiversity in the Gascoyne Marine Park region based on the eDNA detections and known species pool.
• Design integrated deep-water transect samplers based on the study's goal to test a new eDNA sampler.

Strengths

• Data collection occurred during a dedicated 30-day research voyage (November 19 to December 19, 2022).
• Methodological validation is described, comparing eDNA results with bottom trawl surveys and a 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.
