GLERL’s OSAT (Observing Systems and Advance Technology) team, in collaboration with the Michigan Technological University’s (MTU) Great Lakes Research Center, is preparing to deploy the Wave GLIDER SV2 to expand its monitoring capacity in the Great Lakes. The Wave GLIDER functions as an autonomous surface vehicle that uses wave energy propulsion and communicates via Iridium satellite, providing real-time data back to users. This wave powered vehicle can be fitted with numerous instruments to collect data on a variety of physical characteristics of the lakes, including: waves, CTD (conductivity, temperature, depth), and currents. These data can be used for remote sensing algorithm validation. With the instrumentation on board, the Wave GLIDER  can continuously run transects throughout much of the year in all Great Lakes weather conditions and can be piloted and monitored by researchers at GLERL.

The two Liquid Robotics-designed Wave Glider SV2 platforms, to be deployed in the upcoming field season ,were surplused to GLERL by NOAA’s National Data Buoy Center (NBDC) in FY 2016. To ensure safe and reliable operation of these persistent, autonomous data collection platforms, Steve Constant and Steve Ruberg participated in a three-day training in Kawaihae, Hawaii at the Liquid Robotics Training Center this past January. They were accompanied by colleagues Russ Miller (Cooperative Institute for Limnology and Ecosystems Research (CILER)), Jamey Anderson (MTU), and Chris Pinnow (MTU). The training focused on instrument assembly, care, programming, piloting, and deployment and retrieval of the newly acquired wave glider units.

The vehicles, as currently configured, will be used for real-time observations supporting commercial shipping and validation of operational forecasts and satellite remote sensing products. Future applications include mapping of hypoxic zones impacting drinking water and acoustic fisheries parameters in U.S. coastal and Great Lakes regions.
