2017 Development and testing of an inexpensive GPS radio buoy system for early notification of whale entanglements

Project Title: Development and testing of an inexpensive GPS radio buoy system for early notification of whale entanglements

Year: 2017

Principle Investigators: Liese Siemann, Samir Patel, Farrell Davis

Client: Marine Mammal Commission

This project will develop and test an inexpensive GPS radio buoy system, using open-source software and inexpensive components, to provide early notification of marine mammal entanglements in the vertical buoy lines of commercial fishing gear. CFF will develop a new technology to manage the impacts of commercial fisheries on marine mammals. By improving rapid response to entanglements, this solution could improve the frequency and success of disentanglement efforts. Automated detection of line breakage or displacement of gear, a critical feature of the system for locating and tracking entangled animals, will be accomplished by tracking buoy locations immediately after the gear is set, vertical line lengths, and water depth.
