Environmental Variability during the CHURCH STROKE II Cruise 5 Exercise

During the period 9 November through 16 December 1977, 160 XBTs and 127 AXBTs were deployed during Cruise 5 of the CHURCH STROKE II Exercise in the Philippine Sea. The environmental data collection effort was centered around the exercise baseline 12-20 N along 132 E and at various acoustic sites along this track. In addition, oceanographic data were collected along an acoustic projector tow located in the vicinity of the southern end of the Ryukyu Island arc. AXBT probes were deployed by the Oceanographic Development Squadron Eight VXN-8 aircraft throughout these areas to coincide with acoustic events.
