9. Remote Acoustic Monitoring Platform (RAMP)

10. Acoustic Environmental Monitoring
Passive acoustic monitoring detecting and tracking harbour porpoise clicks and dolphin clicks and whistles
Active acoustic monitoring identifying objects close to the rotor
Real time tracking capability – shift from position of analysing all data post-hoc
Each hydrophone unit has a cluster of 3 hydrophone elements – small close together clusters optimised design for localisation (‘large’ time delays between further apart hydrophones can cause ambiguities in matching detections on different hydrophones. Spacing 20-30cm
Envisaged that only 8 channels of data will be analysed in real time (detection and localisation)
A visual display will alert the operator and also show estimated positions (range and bearing) of detected clicks and whistles on a map. An audible alarm will also be set up for both clicks and whistles to assist the operator.
Depending on ambient noise should be able to detect and track HP between 1-200m (dolphins detect ~1km)
Modelling to look at lcoalisation accuracy – very good accuracy (cms) within tens of metres
