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.

The man, the myth, the legend... A.Fisk providing partner update @ the ⁦@LampreyControl⁩ research meeting today. ⁦@RAEON_⁩

RAEON is here today at the @UWindsor spring open house. Come by & learn about our network and what we are up to with these gliders! @EESWindsor @GLIERUWINDSOR @ScienceUWindsor

New blog post!!

Like #GreatLakes data? Then you're in luck! 8 years of underwater glider data from @CIGLR_UM is now available to the public on NOAA's Integrated Ocean Observing System's (@usioosgov) Data Assembly Center map. https://t.co/9sX2hEXgto

#GreatLakesSci #data @NOAA

Love the new logo @RAEON_ , thanks for having me today to provide some hands on training of the @ProOceanus PCO2 sensors!

Had a blast at #GLATOS2020 ! Looking forward to some exciting + new collaborations!

Next, @fisk_lab primes us for collaboration with the @RAEON_ program, a @InnovationCA / ORF-RI funded program are excited to receive additional collaborative direction from #GLATOS2020 via initiatives like equipment sharing. I'm very excited for their glider programme especially!

Lake Erie is now the most wired and connected of the Great Lakes w/ around 20 public and private smart buoys that can text the latest lake observations, including air and water temperatures, wind speed, pH and wave height -

Water sensors, data collaboration make Great Lakes smarter

The Great Lakes Observing System has created “Smart Great Lakes,” by making it easy for the public and policy makers to access data from b...

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 ...
