IN2022_V09: Environmental DNA Data from Gascoyne Marine Park Voyage

November 19 to December 19, 2022, environmental DNA (eDNA) data was collected aboard the RV Investigator voyage IN2022_V09 in the Gascoyne Marine Park. The study compared three eDNA processing methods and validated fish detections against trawl survey data and a known regional species pool. The dataset is provided by the Australian Ocean Data Network.

Use Cases

• Compare eDNA capture efficiency based on the three described processing methods (filtering OCD water, extracting from sponge pieces, filtering sponge rinse water).
• Validate eDNA-based fish species identifications against concurrent bottom trawl survey data.
• Assess marine biodiversity in the Gascoyne Marine Park region using integrated eDNA samples from deep-water transects.

Strengths

• Data collection occurred during a defined 31-day voyage from November 19 to December 19, 2022.
• Methodology includes a comparison of three distinct eDNA processing techniques, allowing for methodological evaluation.
• eDNA identifications were cross-referenced with physical trawl survey data and a known regional species pool for validation.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to the single voyage in the Gascoyne Marine Park.
