Weddell seal (Leptonychotes weddellii) and leopard seal (Hydrurga leptonyx) vocalizations were collected via passive acoustic monitoring 5.6 km seaward from Davis Station, East Antarctica. Eight-minute recordings were manually sampled hourly over 24 hours every 10 days from 24 July 2021 to 30 January 2022. The dataset likely contains daily call counts, showing seasonal and diel patterns influenced by ice cover and seal behavior.
Use Cases
- Analyze seasonal vocalization patterns based on call counts collected from July 2021 to January 2022
- Study diel calling behavior based on hourly sampling intervals mentioned in the description
- Investigate predator-prey acoustic interactions based on concurrent Weddell and leopard seal call detections
- Correlate seal vocal activity with environmental conditions based on landfast ice and open water presence
- Model seal population dynamics based on behavioral shifts from foraging to breeding aggregations
Strengths
- Data spans a defined period from 24 July 2021 to 30 January 2022
- Recordings were made at a specific location 5.6 km seaward from Davis Station
- Sampling protocol is described: 8-minute recordings sampled hourly every 10 days
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 bias inherent to a single Antarctic monitoring site
