3D Trajectories and Positioning Data of 305 Antarctic Krill from the 2021 TEMPO Survey

305 Antarctic krill were tracked using an array of 10 GoPro Hero-8 cameras deployed into swarms during the RV Investigator voyage IN2021_V01 from 29 January to 24 March 2021. The data, collected by the Australian Ocean Data Network as part of the TEMPO survey, includes head and tail coordinates and 3D tracks from video frames. The primary goal was to support krill biomass estimates for updating catch limits in CCAMLR's Division 58.4.2-East.

Use Cases

• Modeling individual krill 3D movement and swarm dynamics based on head and tail coordinates.
• Estimating krill biomass for fisheries management based on positioning data from natural conditions.
• Replicating and validating behavioral analysis methods from Burns et al. (2023) based on the described swarm study.
• Analyzing spatial distribution and orientation within krill swarms based on the provided 3D coordinates.

Strengths

• Data includes coordinates for 305 individual krill, providing a substantial sample for behavioral analysis.
• Observations were made in natural conditions using an array of 10 cameras, suggesting a multi-perspective capture method.
• The dataset is structured into two distinct parts (TEMPO_Orientation and TEMPO_Tracks), likely offering organized behavioral data.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count for the track data is unknown, which may limit suitability assessment.
• Data may reflect geographic/temporal bias inherent to the single voyage and location off the Australian Antarctic Territory.
