RV Investigator IN2022_V09: eDNA Data from Gascoyne Marine Park Survey

Environmental DNA (eDNA) data collected during the RV Investigator voyage IN2022_V09 from November 19 to December 19, 2022. The study aimed to design and test a deep-water transect eDNA sampler, comparing three processing methods: filtering OCD water, extracting eDNA from sponge pieces, and filtering sponge rinse water. Fish identifications from eDNA were compared with bottom trawl survey data and the regional species pool for validation.

Use Cases

• Compare eDNA detection efficacy for fish species based on the three described processing methods.
• Validate eDNA survey results against traditional trawl survey data collected during the same voyage.
• Assess species biodiversity in the Gascoyne Marine Park region using integrated transect samples.
• Benchmark eDNA sampler performance for deep-water marine environmental monitoring.

Strengths

• Data collection is tied to a specific, documented research voyage (IN2022_V09) with known dates and location.
• Includes methodological comparison of three distinct eDNA processing techniques.
• Provides validation context through comparison with concurrent trawl survey data and the 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 analysis.
• Data may reflect geographic and temporal bias inherent to the single voyage and location.
