Rutford Ice Stream DAS Dataset for Antarctic Microseismicity Studies

Multiple files contain Distributed Acoustic Sensing (DAS) seismic data and icequake event catalogs from the Rutford Ice Stream in Antarctica. The dataset includes DAS data from both buried and unburied fiber optic cables, alongside geophone network coordinates and event catalogs for line and triangle deployment geometries. Data was collected by Thomas Hudson at the University of Oxford and is associated with a published scientific study.

Use Cases

• Compare icequake detection performance based on DAS versus geophone sensor data.
• Analyze seismic wave propagation based on DAS data from buried and unburied fiber optic cables.
• Study ice stream dynamics and microseismicity using event catalogs with precise spatial coordinates.
• Validate DAS as a tool for cryospheric monitoring based on Antarctic field deployment data.

Strengths

• Includes data from multiple sensor geometries (line and triangle) and types (DAS and geophones), allowing for comparative analysis.
• Provides raw seismic data files (MSEED format) alongside processed event catalogs.
• Contains specific event files with DAS observations +/- 10 seconds around event origin times.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and dataset size are unknown, which may limit suitability assessment.
• Last update date is unknown; freshness unverified.
