CHURCH OPAL Research and Promulgation

Abstract

CHURCH OPAL was among a series of classified ocean acoustic measurements done in the seventies to support development of undersea surveillance systems. The long-term goal of the current ONR project was to demonstrate that midwater acoustic data recorded on magnetic tape during these Fleet exercises is recoverable with original accuracy and fidelity. A companion goal was to declassify related documentation and promulgate information to enhance general accessibility and technical value to the scientific community. The primary objective of the project was to recover, digitize, and assess validity of the 11-day magnetic tape record from the CHURCH OPAL Exercise.
