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.
