Seismic Profiling Systems.
Abstract:
A Seismic Profiling System was delivered on 30 January 1978 for temporary installation and operation aboard the NR-1. In order to have the equipment installed and tested in time for a planned mission, it was necessary to substitute an Edo Model 550A recorder in lieu of the final Model 615-2 recorder. The model 615-2 recorder was still in production at this time, but was subsequently delivered to the NR-1 and the Model 550A recorder was returned to the vendor. It has been reported that the seismic profiling equipment performed satisfactorily during the entire mission. The Model 615-2 recorder which has replaced the Model 550A recorder is more compact and mounts in the 2300 equipment rack, a considerable advantage over the unwieldy size of the latter recorder. The final equipment was delivered in accordance with the contract requirements.
