RV Investigator Voyage IN2022_V09 eDNA Data from Gascoyne Marine Park

Environmental DNA data was collected aboard the RV Investigator during voyage IN2022_V09 from November 19 to December 19, 2022. The study compared three eDNA processing methods and validated fish detections against trawl survey data. The dataset is hosted by the Australian Ocean Data Network.

Use Cases

• Compare eDNA capture efficiency based on three described processing methods: filtering OCD water, extracting from sponge pieces, and filtering sponge rinse water.
• Validate eDNA metabarcoding results for fish communities by cross-referencing with concurrent bottom trawl survey data.
• Assess the feasibility of integrated eDNA sampling over deep-water transects for marine park monitoring.

Strengths

• Data collection occurred over a defined 31-day voyage period in a specific geographic area.
• Methodology includes a comparative framework for three distinct eDNA processing techniques.
• Validation approach uses independent 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.
• Data files are listed as PNG and HTML, suggesting primary data may be embedded in reports rather than raw structured tables.
