Antarctic Blue and Fin Whale Acoustic Recordings and Annotations, Casey Station 2019

Approximately 200 hours of underwater acoustic recordings collected at Casey Station, East Antarctica, 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-observer capture-recapture analysis. It is associated with a forthcoming publication in Methods in Ecology and Evolution.

Use Cases

• Training automated whale call detectors based on multi-observer adjudicated ground truth annotations.
• Conforming capture-recapture detection probability models based on independent observer detection histories.
• Analyzing seasonal patterns of Antarctic blue whale song units based on recordings distributed throughout the year.
• Comparing human analyst performance against automated detectors like the Ishmael spectral correlation coefficient.

Strengths

• Approximately 200 hours of calibrated acoustic recordings from a deep-water (~2700 m) mooring.
• Adjudicated ground truth from three independent human analysts for multiple call types.
• Recordings represent approximately 2% of total annual effort, selected to be broadly representative of yearly conditions.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
