The Marine National Facility RV Investigator voyage IN2019_V01 collected photogrammetric video tracking data in the Southern Ocean between 19 January and 5 March 2019. The dataset includes approximately 18 hours of video tracking conducted on 24 occasions, primarily targeting Antarctic blue whales with additional observations of fin whales. It provides baseline information on cetacean surface behaviour and movement to support investigations of whale behaviour, movement patterns, and vocal activity.
Use Cases
- Analyze fine-scale whale movement patterns based on precise surface location measurements.
- Study the relationship between whale surface behaviour and vocal activity as mentioned in the description.
- Investigate the availability of Antarctic krill to large predators based on whale tracking data.
- Model cetacean movement relative to a research vessel using range and bearing data.
Strengths
- Data collection occurred over a defined voyage period from 19 January to 5 March 2019.
- Video tracking was conducted on 24 occasions for a total of approximately 18 hours.
- The system enabled precise measurements of surface locations and fine-scale movement.
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 voyage.
