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 dataset, collected by the Australian Ocean Data Network, includes head and tail coordinates and 3D tracks from video frames. The primary goal was to support biomass estimates for updating krill catch limits in CCAMLR's Division 58.4.2-East.
Use Cases
- Modeling krill swarm dynamics based on 3D trajectory data.
- Estimating krill biomass for fisheries management based on individual tracking.
- Studying individual krill behavior in natural conditions based on video frame coordinates.
- Replicating swarm study methods from Burns et al. (2023) based on the described methodology.
Strengths
- Data includes 305 individual krill with head and tail coordinates.
- Observations were made using a specific array of 10 GoPro Hero-8 cameras.
- Data collection occurred during a defined voyage 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.
- Data may reflect geographic/temporal bias inherent to the specific survey voyage.
