Between 29 January and 24 March 2021, the RV Investigator voyage IN2021_V01 collected acoustic data for the TEMPO survey. The dataset contains approximately 460 hours of underwater recordings from 251 deployed DIFAR sonobuoys, contributed by the Australian Ocean Data Network. Recordings are intended to complement visual observations for predator studies.
Use Cases
- Detect blue whale and sperm whale vocalizations based on acoustic recordings
- Analyze marine mammal presence and distribution based on sonobuoy recordings
- Study Antarctic krill predator dynamics based on acoustic data complementing visual observations
- Investigate ocean noise patterns based on recordings from deployed sonobuoys
Strengths
- 251 deployed sonobuoys provide a substantial sampling effort
- Approximately 460 hours of recordings offer a long temporal series
- Specific sonobuoy models (AN/SSQ-53F, Q53F, SDSQ955 HIDAR) are documented
Limitations
- Column-level documentation is absent; field semantics must be inferred after download
- Row count is unknown, which may limit suitability assessment
