Environmental DNA sequence data and video observations were collected during the 2021 TEMPO voyage in the East Antarctic sector of the Southern Ocean. The dataset comprises 110 eDNA samples from surface and near-seafloor seawater, analyzed with a euphausiid-specific metabarcoding marker, alongside CTD-mounted camera footage. It was acquired during the RV Investigator research voyage IN2021_V01 from January to March 2021.
Use Cases
- Detect krill species presence based on eDNA metabarcoding data mentioned in the description
- Analyze krill swarm distribution relative to oceanographic features based on sampling locations
- Correlate visual observations from video footage with genetic data from eDNA samples
- Model euphausiid biodiversity patterns in the East Antarctic region based on the survey scope
Strengths
- Includes 110 eDNA samples from both surface and near-seafloor depths
- Combines genetic (eDNA metabarcoding) and visual (video footage) observation methods
- Data collected during a dedicated research voyage (IN2021_V01) with a specific scientific survey objective
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/temporal bias inherent to the single 2021 voyage
