Medium-term acoustic monitoring of small cetaceans in Patagonia, Chile.

Coastal dolphins and porpoises such as the Chilean dolphin (), the Peale's dolphin (), and the Burmeister's porpoise () inhabit the remote areas of Chilean Patagonia. Human development is growing fast in these parts and may constitute a serious threat to such poorly known species. It is thus urgent to develop new tools to try and study these cryptic species and find out more about their behavior, population levels, and habits.
