A prototype | HF Radar | And a *tiny* buoy:

Early Warning System prototype shown at IAGLR conference

At IAGLR last week, Tim, our senior technical advisor, presented a prototype system that takes data from a sensor, sends it to the cloud, and automatically texts an alert if a certain parameter exceeds a limit (in this case turbidity). 

During the demo, as Tim moved the sensor from the clear water to the murky, the turbidity spiked, and a text alert with a link to the displayed info arrived on his iPhone.  

This prototype proves one technical piece of an early warning system for Lake Erie, a project GLOS is leading through a IOOS OTT program grant. Partners include NOAA GLERL and NCCOS, CIGLR, Ohio State University, LimnoTech, and Cleveland Water Alliance. Read more here
(Above) Tim demonstrates how moving a sensor from clear water to murky spikes turbidity readings. (Below) The prototype demonstrates how data from multiple sources can power various applications like alerts.   

High Frequency Radar installation is underway

Soon, real-time, high quality surface current data will be available in the Straits of Mackinac.

Through GLOS funding, researchers Lorelle and Guy Meadows are testing and working to install the technology.

With the goal of creating a new vector map every half hour, the technology will have applications from search and rescue and navigation to spill cleanup and even current model support. Read the story and watch the video from Michigan Technological University here.


This will be the first HF radar used in the Great Lakes. See data from installations in other IOOS Regions here
 
Photo of the Month: Yep. It's a tiny model buoy. 

David Cannon, a Purdue civil engineering PhD candidate, created this scale model of Buoy 45170 which floats outside Michigan City, Indiana. "Goliath" features a 3-D printed base with important bits glued on: a tiny model temperature sensor, makeshift solar panels, and a little antenna. 

The real 45170, built by LimnoTech, is part of the Illinois-Indiana Sea Grant network and shares data with GL Buoys. Follow this buoy and its counterpart in Wilmette on Twitter @TwoYellowBuoys
