I set up an observer program using volunteers on offshore gill-netters that showed a bycatch of 2000+ porpoise per year in the Celtic Sea. That lead to developing devices to monitor and reduce interactions ... more observer programs ... and eventually leaving medecine to concentrate on that work.
My current focus is design and testing of acoustic pingers to reduce cetacean bycatch and development of echo-location loggers for cetaceans and bats. The main target (for me) of the loggers is monitoring population trends and impacts, with a focus on achieving low-cost accurate trend monitoring. That requires automated detection which must deal with the many sources of sounds with overlapping characteristics. To address that I am working on train detection methods i.e. moving up from click-by-click classifiers to take in a wider view of the acoustic events. I continue to work with fishery issues that threaten the survival of several small cetacean species.
