Beyond the Gulf: Real-Time AUV Tracking

Posted: January 30, 2019

The GCOOS data portal used to track Gulf glider missions in real-time has proven so popular and easy-to-use by glider operators that we’re now tracking other autonomous ocean-going vehicles in other locales. We’ve tracked a Navocean Nav2 Sail and Solar ASV being used to gather data in the Banana River Lagoon on Florida’s east coast.

Navocean and Turner Designs teamed up with FAU/HBOI researcher Dr. Jordon Beckler and 4Ocean to demonstrate mobile fluorometer data collection in support of new techniques to research red tide and other toxic algae blooms — including HABs in Lake Okeechobee — through the deployment of the Navocean “Nav2” vehicle, the first autonomous sail-driven surface vehicle to be used for inland algae monitoring.

Harmful algae blooms (HAB) in coastal marine environments are increasing in number and duration, pressuring local resource managers to implement mitigation solutions to protect human and ecosystem health. However, insufficient spatial and temporal observations create uninformed management decisions. In order to better detect and map blooms, as well as the environmental conditions responsible for their formation, long-term, unattended observation platforms are desired. In this article, we describe a new cost-efficient, autonomous, mobile platform capable of accepting several sensors that can be used to monitor harmful algae blooms in near real-time. The Navocean autonomous sail-powered surface vehicle is deployable by a single person from shore, capable of waypoint navigation in shallow and deep waters, and powered completely by renewable energy. We present results from three surveys of the Florida Red Tide harmful algae bloom (Karenia brevis) of 2017-2018. The vessel made significant progress towards waypoints regardless of wind conditions while underway chl. a measurements revealed HAB bloom patches and CDOM and turbidity provided environmental contextual information. While the autonomous sailboat directly adds to our HAB monitoring capabilities, the boat can also help to ground-truth and thus improve satellite monitoring of HABs. Finally, several other pending and future use cases for coastal and inland monitoring are discussed. To our knowledge, this is the first demonstration of a sail-driven vessel used for coastal HAB monitoring.
