RV Investigator Voyage IN2022_V09: Environmental DNA Data from Gascoyne Marine Park

Environmental DNA (eDNA) data was collected during the RV Investigator 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 and the regional species pool. The dataset is provided by the Australian Ocean Data Network.

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 species detection accuracy based on comparison with bottom trawl survey data mentioned in the description
• Assess regional marine biodiversity based on eDNA detections referenced in the study
• Design deep-water transect eDNA samplers based on the sampler technology tested during the voyage

Strengths

• Data collection occurred over a defined 31-day voyage from November 19 to December 19, 2022
• Methodology includes validation against independent trawl survey data and a known regional species pool
• The dataset is associated with a specific research voyage (IN2022_V09) focused on a defined marine park

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• The primary file formats are PNG and HTML, which may not contain structured, machine-readable data
