| Outline of Final Research Achievements |
We investigated effects of ship noise on marine mammals by using a fully-rigged sailing ship off Japanese Isles and by using a sailing yacht and powered ship near Notojima with towed underwater acoustic sensors. In the former survey, frequency to meet marine mammals was not so high that we failed to obtain significant data. On the other hand, in the latter survey, we frequently measured responses of groups of Indo-Pacific bottlenose dolphin to two types of ship. The results demonstrates that no significant difference in their responses between the sailing ship and the motor ship at low speed.
