Active Sonar + Marine Life

I would be interested if there are any marine life surveys taken from the early 1960's through the early 1980's. That was really the early heyday of high-powered active sonars like the SQS-26 models. There weren't any mass dolphin or whale kills from that time as I remember. The reason I keep hearing for such kills seems to be bacterial infections caused by compromised immune systems. I've never heard of acoustics being the cause of that.
