R/WAR italian deep seismic data

Some info on seismic data processing
The original seismic data were recorded or in analog form (magnetic tape FM-recordings, up to '90) or in digital form (floppy discs), after the first digital data-loggers became available in the '90s.


  ANALOG data (FM recordings)

The italian data were first collected, in Italy and in Europe, and then properly digitized, using an ad-hoc procedure.
The final step was the Ascii data file transfer to a local PC.
The whole process is described here [www].

  DIGITAL data

Atfer the acquisition of 20 Lennartz M88/FD data-loggers in the '90, for some years the italian seismic profiles have been carried out in mixed diployments, using both analog and digital data-loggers.
The data processing of such data-files, used a set of new software modules, furnished by the Lennartz and/or self written. Some useful information is given here.
