| Abstract(in English) | Recently, the climate research of Ocean using Autonomous Underwater Vogel (AUV) is being planned in Antarctic Ocean. In order to know the characteristics of sound propagation in Antarctic Ocean for communication and operation to AUV, we calculated the characteristics of sound propagation used by ray theory and parabolic equation method. Sound speed profile was calculated measurement data of Japanese Antarctic Research Expedition (JARE-31) in 1991 [1]. It was assumed that the transmitter was placed at 100m in depth and propagation range was 39km in OW traverse line. We have investigated about the influence of bottom shape for sound propagation in Antarctic Ocean model that was covered ice layer for 39km in range. |
