Abstract

Long-range recording of COCORP vibrators was undertaken in the Adirondacks using a radio repeater to retransmit the vibrator start-up code at ranges up to 100 km. A number of events were recorded at a range of 47 km; these events correspond to reflections from depths of about 9, 13, 16, 20, and 24 km and a possible Moho reflection from 40 km might be present. Simulation of VIBROSEIS recording demonstrates that low-level signals with a S/N as low as 0.05 may be extracted from noise even though reflections have amplitudes less than the least significant bit. Such wide-angle VIBROSEIS recording is practical and necessary in crustal reflection studies for defining the Moho and other deep reflectors.-Authors
