I work at the Sea Mammal Research Unit studying marine mammal bioacoustics. My interest lies in developing passive acoustic monitoring (PAM) technology which can be used to help address current conservation issues.
Projects at the moment:
Porpoises in tidal rapids: In tidal rapid areas, we have been pioneering the use of low cost autonomous vertical hydrophone arrays to provide detailed information on dolphin and porpoise diving behaviours. This is to help us understand how the introduction of tidal turbines in these so far poorly understood habitats might affect animals.
Tracking Porpoises around gill nets: Gill nets are by far the largest cause of anthropogenic related mortality in harbour porpoises and many delphenid species. Despite this we have very limited knowledge on how wild animals behave near to and in the vicinity of gill nets. Almost all detailed behavioural studies so far have been performed on captive animals. We are developing low cost micro aperture PAM arrays which will be deployed within gill nets fisheries to collect detailed data on harbour porpoise movements near nets.
PAMGuard. Signal processing is complex. PAMGuard is an open source software platform for PAM analysis. I’ve contributed a lot to the project and am currently exploring the use of JavaFX to provide a more up to data GUI.
