Very Broad Band Seismological Data in Terranova Bay Since 1989
Listed in NASA Earthdata CMR
Seismic data recorded at Terra Nova Bay very broad band station TNV are currently available in binary SAC Format.
Description
The sensor is a very broad band seismometer, whose response function is flat between 360 and 0.1 seconds. The dynamic range spans over 140 dB, thanks to the 24 bits of the Quanterra digitizer.
The site is a cave of about 10 meters inside the granite, at a few hundreds of meters from the Italian Base. The cave has been divided into two rooms, in order to ensure as mach insulation as possible from the outside temperature and pressure variations. Although the station was installed permanently and should record continously, for different reasons only relatively short data chunks of about 2 months per year are available.

- In 1991 the station was operating from Feb 18th (049) to Apr 24th(114).
- In 1992 from Jan 10th (010) to Mar 16th (076). A list of data records is on line for years 1991 and 1992. Data concerning these two periods are now available via automatic request at FIS URL ("bounty.ingrm.it/data-center.html") Technical information (response function, station location, etc.) about the station, as well as a list of the data now released, can be also requested via the same form. A brief official description of TNV station is in the IRIS Station Book as well as at FIS Web site.
