TEMPO: 3D Trajectories of 305 Antarctic Krill from 2021 Survey

305 Antarctic krill had their head and tail coordinates recorded using an array of 10 GoPro Hero-8 cameras. The data was collected during the RV Investigator voyage IN2021_V01 from 29 January to 24 March 2021 to support krill biomass estimates for catch limits in CCAMLR's Division 58.4.2-East. The dataset is provided by the Australian Ocean Data Network and includes two parts: orientation coordinates and track coordinates from video frames.

Use Cases

• Modeling 3D individual krill movement based on head and tail coordinate data.
• Estimating krill biomass for fishery management based on swarm observation methods.
• Studying krill behavior in natural conditions based on video frame coordinate tracks.
• Replicating swarm study methods from Burns et al. (2023) for comparative analysis.

Strengths

• Data includes 3D coordinates for 305 individual krill.
• Observation method uses an array of 10 cameras for detailed individual tracking.
• Data collection occurred during a dedicated 55-day research voyage.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count for the track coordinates is unknown, which may limit suitability assessment.
