Continuation of reel # 11, Dr. Winn wanted a clear 45 minutes of sound without playback xmittions present. 2 animals within 300 feet most of this reel - stronger sounds maybe attributed to them. The strongest low frequency one goes thru a call - but not the regulation type we are use to hearing from individuals. During this call, the second animal holds a low level cry (see saw rythum [sic]) or lowing sound." SEAOCEAN TEMPAIR: 27
