TEMPO: 3D Trajectories and Positioning of Antarctic Krill from 2021 Survey

3D coordinates of individual Antarctic krill were collected during the RV Investigator research voyage IN2021_V01 from 29 January to 24 March 2021. The data were obtained using an array of 10 GoPro Hero-8 cameras deployed into krill swarms to study individual behavior. The primary goal was to support estimates of krill biomass for updating catch limits in CCAMLR's Division 58.4.2-East.

Use Cases

• Modeling 3D swarm dynamics based on head and tail coordinates of 305 krill.
• Analyzing individual krill movement patterns from video frame coordinate tracks.
• Estimating krill biomass for fisheries management based on observed swarm density and behavior.
• Studying predator-prey interactions by examining krill positioning and orientation data.

Strengths

• Data includes 3D coordinates for 305 individual krill, providing individual-level detail.
• Collection used an array of 10 GoPro Hero-8 cameras, suggesting multi-angle observation.
• Voyage occurred over a defined period from 29 January to 24 March 2021.
• Dataset is structured into two logical parts: orientation data and track coordinates.

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 the single 2021 voyage.
