| Outline of Final Research Achievements |
For understanding the Ganges River Dolphin's echolocation strategy and underwater behavior, we have been developing the acoustic and motion logger which can be attached to the Ganges river dolphin. To downsize the loger, a built-in hydrophone and pressure sensor (MEMS) unit was newly developed and installed to the prototype to be used for the experiments using an AUV. After comfirming its peformance, an pencil size date logger using the developed built-in unit and its software was finally develped. The experiments using the system along with the non contact type acoustic recording sytem using a 6 hydrophone array were conducted on Novemver 2015 at the Ganges rievrsite. The perfromance of the developed system was demonstreted well. In addition, as an application, a deep sea (2000m) noise recoreder for practical use was realized.
