Transmission Report, Vibroseis CW Acoustic Source, Church Anchor Exercise, August and September 1973

Abstract

The CHURCH ANCHOR Exercise is one of a series of quasisynopic ocean environmental acoustic measurement efforts sponsored since 1968 by the Long Range Acoustic Propagation Project (LRAPP). The area of investigation encompassed 20 deg N to 50 deg N and 135 deg W to 155 deg W and the Exercise was conducted during August and September, 1973. The Exercise involved a total of 11 surface ships and platforms from which acoustic sources, receivers, and environmental measurement systems were deployed and/or towed. The Vibroseis system, towed by the M/V MED SEAL was one of three acoustic sources employed. The Vibroseis source is a hydroacoustic device that is towable at speeds up to 5 knots and 91 meter depths. The source has a frequency range of 5 to 225 Hz. The complete transmission log of the Vibroseis source is presented in this report.
