R/WAR italian deep seismic data

Information on missing data:

a) DIGITIZED data

The original plan of the Project, included only the R/WAR seismic data recorded in Italy and surrounding seas, so some other 'mediterranean' data were not included in the ReWARD archive. For istance the seismic refraction data recorded in Tunisia, during the EGT-'85 survey. If one should want to include also these data, he could retrieve them
from our old TAPE(IBM)-collection (pdf), whose contents were mostly copied in our new ReWARD archive. The digitized data not yet included in ReWARD archive are the following:

TUNISIA
E.G.T.many (see map)
can be retrieved from SALVA-TUN digital tape (IBM).
A copy of such tape with all the compiled EGT-Tunisian data was distributed to all European Partners at EUG IV / EGS XII meeting (Strasbourg, March 1987).

CENTRAL
APENNINES
VulsiniBolsena (see map)
can be retrieved from SING-11 digital tape (IBM).
If not, the original mag. tapes could be re-digitized with our HP A/D system still active(1)


b)  data NOT digitized

The following
original magnetic tapes (analog FM recordings, on standard 1/4"reels and/or 1/8"cassettes) are still available at our Lab, but never digitized, because of the difficulties in retrieving all the diployment parameters: shot and/or recording points information. These tapes could be processed and the recorded signals could be extracted and digitized: we tested the quality of the reproduced data ( example ) and obtained good signals. In spite of the age of the tapes it seems that no demagnetization occurred yet... 
In order to process them, the necessary tools and steps are:
a) software: there could be some problem in retrieving all the needed info and parameters (mainly the coordinates of the recording points)
b) harware (A/D system): this is no problem; in our Lab it is still properly functioning the HP system already successfully used(1) and could be used again, for this final step.
