The Australian Ocean Data Network provides data from the 2021 TEMPO voyage in the East Antarctic sector of the Southern Ocean. It includes environmental DNA sequence data from 110 seawater samples and video observations from a CTD-mounted camera system, collected between January 29 and March 24, 2021. The dataset focuses on detecting and characterizing Southern Ocean krill species using a euphausiid-specific metabarcoding marker.
Use Cases
- Detect krill species presence based on eDNA metabarcoding data from seawater samples.
- Correlate visual krill observations from underwater video footage with eDNA detection results.
- Analyze krill distribution patterns relative to sampling depth and location mentioned in the description.
- Study euphausiid biodiversity in the East Antarctic region based on genetic sequence data.
Strengths
- Includes 110 eDNA samples from surface and near-seafloor depths.
- Combines genetic metabarcoding data with approximately 5 minutes of video footage per CTD station.
- Data collection is temporally bounded to a specific research voyage from January to March 2021.
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 and temporal bias inherent to a single voyage in the East Antarctic.
