Motivations of Our Research
• Inspired by previous funded project FOA DE-FOA-0001554:
A Synchronized Sensor Array for Remote Monitoring of
Avian and Bat Interactions with Offshore Renewable
Energy Facilities
• Enable automatic blade-strike detection including event
images storage in OFFSHORE environment
• Decrease uncertainty in statistics of birds/bats fatalities
• Support sites permitting and wildlife monitoring
