Date: 2012/2/5 - 2012/3/30

I visited Instituto Nacional de Pesquisas da Amazônia (INPA) and had the meeting with colleagues. Next I visited Mamirauá Sustainable Development Reserve. In Mamirauá SDR, the clicks and vocalization of free-ranging population of Amazon river dolphins were recorded by the stereo acoustic data loggers which were set at three points. And I conducted census survey and visual observation in the field site. Finally, I visited Punta Arenas, Chile. In Punta Arenas, the clicks of commerson's dolphin were recorded by same system. I succeed to get plenty of data throughout this trip and achieved the objective of this trip.
