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

Antarctic krill coordinates collected during the RV Investigator research voyage IN2021_V01 between 29 January and 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
• Estimating krill biomass for fisheries management based on individual positioning data
• Analyzing individual krill behavior in natural conditions based on video frame coordinates
• Replicating and validating swarm study methods from Burns et al. (2023)

Strengths

• Data includes coordinates for 305 individual krill
• Collected using an array of 10 GoPro Hero-8 cameras for detailed observation
• Voyage spanned a defined period from 29 January to 24 March 2021

Limitations

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