The results of measuring the effects of environmental variables on acoustic transmission in the ocean are summarized in this report. The environment variables were measured both before and during a controlled-geometry submarine exercise, using sensors on a research vessel and an aircraft. The acoustic signals were obtained from the submarines. During the submarine exercises, the SUBIC DDP-24 computer was used to predict the best listening depths for each run, using the most recent sound velocity profile data measuring from the submarine as the input to a ray-trace program. The interpretation of the acoustic signals in the context of the measured environmental variables is the major result of this report. (Author)
