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

The TEMPO dataset from the Australian Ocean Data Network contains 3D coordinates of individual Antarctic krill collected during the RV Investigator 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 individual krill movement and swarm dynamics based on 3D coordinate tracks.
• Estimating krill biomass for fisheries management based on positioning data.
• Studying krill behavior in natural conditions based on head and tail coordinate data.
• Replicating and validating swarm study methods from referenced scientific literature.

Strengths

• Data includes coordinates for 305 individual krill in the TEMPO_Orientation component.
• Data collection used an array of 10 GoPro Hero-8 cameras for detailed observation.
• Voyage occurred over a defined period from 29 January to 24 March 2021.

Limitations

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