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 depths, analyzed with a euphausiid-specific metabarcoding marker, alongside CTD-mounted camera footage. Data were acquired by the Marine National Facility aboard the RV Investigator between 29 January and 24 March 2021.
Use Cases
- Detect and characterize Southern Ocean krill species based on euphausiid-specific metabarcoding of eDNA samples.
- Analyze krill swarm distribution and behavior by correlating eDNA presence with concurrent video observations.
- Study euphausiid biodiversity across different ocean depths using samples from surface and near-seafloor CTD stations.
Strengths
- Includes 110 eDNA samples collected from both surface and near-seafloor depths.
- Data collection is temporally bounded to a specific research voyage from 29 January to 24 March 2021.
- Multimodal dataset combining genetic sequence data with visual video observations.
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 bias inherent to the specific East Antarctic survey area.
