The Real-Time Aquatic Ecosystem Observation Network (RAEON) provides the infrastructure, staff and data management that Canadian researchers need to carry out cutting-edge, integrated and transformative research on the Great Lakes. RAEON improves understanding of the mechanisms and processes of large lake ecosystems and contributes to the management, rehabilitation and enhancement of their ecosystem services.

Don't forget, you can check out our live buoys via @GLOS https://t.co/WdgmEK03Oe

Nice to see another of our #slocumgliders is off doing important work! Thanks @RAEON_ for sharing a glimpse of Cormorant(?) as it heads off to do its work! Safe travels @TeledyneMarine https://t.co/zHbrpSJAAa

Maiden voyage of the cormorant in Lake Erie today! HUGE thanks to @USGS @CIGLR_UM @eriefishdoc @NOAA_GLERL for the support. The cormorant will be collecting various water quality measurements throughout the month of Sept. Stay tuned for updates. @ScienceUWindsor @TeledyneMarine

Back at it on Lake Erie! 1/3 buoys deployed to support hypoxia modelling @NOAA_GLERL @fisk_lab @ScienceUWindsor @RealGLOS @ErieWatch

"This year’s bloom is expected to measure 4.5 on the severity index – among the smaller blooms since 2011 – but could possibly range between 4 and 5.5, compared to 7.3 last year."

Just in: #NOAA and partners are forecasting a moderate harmful algal bloom for western #LakeErie this summer. Low amounts of spring rainfall led to a smaller nutrient load than last year. Read more: https://t.co/pUNLzFPNAs #HABsForecast

@GLATOS_Fish pairing up with @RAEON_ Their combined capacities will help pair fish movement with environmental conditions. #iaglr20 @eriefishdoc

Thank you @DrPlanktonguy !!

Just testing out the waters 🤿 💨

Check out this test dive by our recently deployed IMOS Ocean Glider in the #GreatBarrierReef. Our Ocean Gliders always take a few test dips before we send them on their way. Thanks to @Australia and @citizensGBR for capturing this moment 📹

GETTING REAL: REAL-TIME TECHNOLOGY PROVIDES GREATER INSIGHT ON WATER QUALITY ISSUES
Harmful algal blooms (HABs) and the low dissolved oxygen concentrations associated with them are a growing concern for large water bodies throughout the world. HABs have resulted in fish kills and drinking water advisories, which collectively have caused estimated economic losses of up to US$71 million per year within Lake Erie alone. HABs have been ...

Text a buoy and it’ll text you back: Making Lake Erie the most connected Great Lake
Laura Johnston, Cleveland.com – October 9 2019 CLEVELAND, Ohio – The biggest wave in Lake Erie this past summer topped 11 feet. The highest water temperature reached nearly 80 degrees. That’s according to data from a smart buoy near Cleveland’s water intake crib, about 3 miles north of the downtown shore. Lake Erie has about ...

Have you seen this buoy? Windsor scientist hoping to recover data, scientific equipment
CBC News Jonathan Pinto – August 8, 2019 A University of Windsor professor is missing a high-tech scientific research buoy used for studying Lake Erie algal blooms. On Wednesday, Jill Crossman was on western Lake Erie as part of the annual “HABs Grab” — an international scientific endeavour that saw scientists collect roughly 200 water ...
