Abstract:

The ground motion data obtained across a geologic interface on MIGHTY EPIC Interface Experiment were converted to digital format and stored in three hardened canisters deep underground. The data were retrieved after the test by transmitting a coded signal through the earth that caused a particular canister to transmit stored digital data to a receiver on the surface where they were recorded as serial digital information. This report discusses the data reduction technique used to produce graphical output from the tape, presents all of the data as plots and notes the anomalies in system performance. One canister was found to have stored ground motion data, the other two had stored no motion data. A later interrogation showed that the memory units had been reset. The reason is not known. Recommendations are made for 1 recovery of one of the canisters to ascertain the cause of rewriting and 2 a change in output data format to make data analysis easier. Author
