Antarctic Whale Acoustic Recordings and Annotations, Casey Station 2019

Approximately 200 hours of underwater acoustic recordings from Casey Station, Antarctica, collected between December 2018 and December 2019. The dataset includes independent annotations by three human analysts and automated detections for Antarctic blue and fin whale calls, supporting a multi-obobserver capture-recapture analysis. It is associated with a forthcoming publication in Methods in Ecology and Evolution.

Use Cases

• Evaluate automated whale call detectors based on adjudicated ground truth annotations.
• Perform multi-observer capture-recapture analysis for detection probability estimation.
• Analyze seasonal patterns of Antarctic blue and fin whale vocalizations based on year-round sampling.
• Compare human analyst performance and consistency for low-frequency whale call identification.

Strengths

• Approximately 200 hours of acoustic recordings sampled at 1000 Hz.
• Annotations from three independent human analysts for multiple call types.
• Includes a subset of recordings selected to be broadly representative of annual conditions.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
