Australian Ocean Data Network provides data on marine mammal interactions with midwater trawl gear, collected using underwater video technology. Digital video data was described according to operational, catch, and interaction fields and is linked to commercial catch and effort data. The dataset was last updated on 2026-04-10.
Use Cases
- Analyze seal behavior around trawl nets based on underwater video observations.
- Evaluate the effectiveness of Seal Excluder Devices based on interaction data.
- Model environmental and operational factors influencing marine mammal interactions based on linked catch and effort data.
Strengths
- Data is linked to commercial catch and effort data, providing operational and environmental context.
- Observations are made time-specific to each trawl shot, enabling temporal analysis.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
