Rutford Ice Stream Seismic Data: DAS, Geophone, and Refraction Travel Times

Seismic data from the Rutford Ice Stream in Antarctica includes 7 hours of continuous Distributed Acoustic Sensing (DAS) data sampled at 100 Hz and corresponding vertical-component geophone data. The dataset also contains refracted P-wave travel time data from a geophone array survey. These data support seismic noise interferometry and refraction inversion to derive subsurface velocity profiles.

Use Cases

• Performing seismic noise interferometry using continuous DAS and geophone data.
• Inverting for P-wave velocity profiles from refraction travel time data.
• Characterizing the firn layer S-velocity structure on an Antarctic ice stream.
• Comparing seismic signals between DAS channels and a co-located geophone.

Strengths

• Contains 7 hours of continuous, time-synchronized DAS and geophone data, enabling direct comparison.
• DAS data is sampled at a high frequency (100 Hz), suitable for detailed seismic analysis.
• Includes specific geolocation information (Rutford Ice Stream, Antarctica) and instrument offset details.

Limitations

• Metadata is incomplete: exact row count, file size, and last update date are unknown.
• The provided column names are unknown, limiting immediate understanding of data structure.
• Dataset scale is limited to a single 7-hour recording period and one specific location.
