305 Antarctic krill had their head and tail coordinates captured in 3D using an array of 10 GoPro Hero-8 cameras. The data were collected during the RV Investigator voyage IN2021_V01 from 29 January to 24 March 2021 to support krill biomass estimates for catch limits in CCAMLR's Division 58.4.2-East. The Australian Ocean Data Network hosts this dataset, which includes orientation and tracking data derived from video frames.
Use Cases
- Modeling individual krill movement patterns based on 3D coordinate tracks.
- Estimating krill biomass and density for fisheries management based on swarm observation data.
- Studying collective animal behavior in natural conditions based on video-derived trajectory data.
- Calibrating acoustic or other survey methods with direct individual observations.
Strengths
- Data includes 3D coordinates for 305 individual krill, providing individual-level detail.
- Observation methods are explicitly described, using 10 GoPro Hero-8 cameras deployed into swarms.
- Temporal coverage is precisely defined from 29 January to 24 March 2021.
- The dataset is structured into two logical parts: orientation data and tracking 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 and temporal bias inherent to the single 2021 voyage.
