Very Broad Band Seismological Data from Terra Nova Bay, Antarctica (1989-1992)

Seismic data recorded at the Terra Nova Bay station (TNV) in Antarctica, with available data chunks from 1991 and 1992. The data is recorded by a very broad band seismometer with a flat response between 360 and 0.1 seconds and a 24-bit digitizer, providing a dynamic range over 140 dB. The station is operated by SCIOPS and data is available in binary SAC format via an automated request system.

Use Cases

• Analyzing seismic event signals based on the very broad band frequency response mentioned in the description.
• Studying long-period seismic waves based on the sensor's flat response down to 0.1 seconds.
• Calibrating or comparing seismometer performance based on the documented 140 dB dynamic range and 24-bit digitizer.
• Investigating site-specific seismic noise based on the station's location in an insulated granite cave.

Strengths

• Sensor has a very broad band flat response between 360 and 0.1 seconds.
• Data has a high dynamic range spanning over 140 dB due to a 24-bit digitizer.
• Station is located in an insulated granite cave to minimize temperature and pressure interference.

Limitations

• Only short data chunks of about 2 months per year are available, not continuous recording.
• Row count, file formats, and column-level documentation are unknown.
• Last update date is unknown; freshness unverified.
