3D Trajectories and Positioning Data of Individuals in an Antarctic Krill Swarm: TEMPO Obs

305 individual Antarctic krill had their head and tail coordinates tracked in 3D during a 2021 research voyage. Data was collected using an array of 10 GoPro Hero-8 cameras deployed into natural swarms to study individual behavior. This work supports biomass estimates for updating catch limits in the CCAMLR Division 58.4.2-East region.

Use Cases

• Modeling individual krill movement and orientation within a swarm based on 3D coordinate tracks.
• Estimating krill biomass and abundance for fisheries management based on observed swarm structure.
• Studying collective animal behavior in natural conditions based on video-derived positioning data.
• Calibrating or validating acoustic survey methods for krill based on direct visual observations.
• Replicating behavioral analysis methods from cited literature (Burns et al., 2023) for comparative studies.

Strengths

• Data includes 3D coordinates for 305 individual krill, providing a substantial sample for analysis.
• Collection used an array of 10 synchronized GoPro cameras, suggesting multi-angle coverage for accurate positioning.
• Voyage occurred over a defined period from 29 January to 24 March 2021, providing temporal context.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count for the TEMPO_Tracks component is unknown, which may limit suitability assessment.
• Data may reflect geographic and temporal bias inherent to the single voyage and specific survey area.
