Chelonia LimitedWildlife Acoustic Monitoring | ||
The intelligent cetacean recorderSince 2006, Chelonia PODs have revolutionised the way we study cetaceans in the wild. These fully automated passive acoustic monitoring instruments detect porpoises, dolphins and other toothed whales (except sperm whales) by recognising the trains of echo-location sounds they produce to detect their prey, orientate and interact. Standard PODs can be deployed to at least 100 metres, while the deep sea version is designed for deployments to at least 2 km. Design AimsThe C-POD and F-POD designs aim to achieve, at low cost:
To achieve these objectives the design is fully integrated from the mechanical engineering of the hardware through to the delivery of statistics-ready results from the FPOD and CPOD apps. Deployment environmentsPODs are in use in a wide range of environments, from the Arctic to the Amazon:
"Chelonia Ltd has, through the development of the T-POD and the successor the C-POD, created a whole new field of conservation research. Through the deployment of non-invasive PODs, data on Odontocete presence and echolocation characteristics now give new insights on animal behaviour and ecology and also make it possible to estimate absolute abundance even in low-density populations."

From these and other studies we have learned that the crucial step required to get very high performance automated detection is to develop the best possible set of train coherence metrics that can be used to reject false claims.
