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.

Looking very forward to planning our @FishOceansCAN #LakeOntario missions with Cailin this week! The newest additions to the @RAEON_ #glider group are tremendous assets. It is going to be an excellent collaboration for years to come.

Just this month - a new tech joined the Great Lakes glider community!

Please welcome Cailin Burmaster to @RAEON_ !

With collaboration underway with @CIGLR_UM UM-Duluth @EPA we are excited for this field season's missions

More on Cailin and RAEON:

Brrr! Ever wonder what our #buoys do in winter? ❄️ Since they're taken out of the water every fall to avoid ice damage, winter is the perfect time to refurbish & prep them for spring deployment! Pictured here are #LakeErie buoys that help us study HABs.

Tracking ice coverage on the Great Lakes plays a key role in determining climate patterns, lake water levels, spring plankton blooms, and more.

Check out the latest #podcast episode of Marine Tech Talk by @TeledyneMarine featuring members of RAEON discussing our first glider mission in Lake Erie! Listen here:

We would like to introduce Cailin Burmaster as our new glider technician! Cailin started working with gliders as a student @DalhousieU @DalGliders and has continued that work @cproof_uvic out West. Join us in welcoming Cailin to the team + the Great Lakes!

Really jazzed to see this awesome @BioSonics gear from @RAEON_ in use! Poised to make some really insightful data from this year and next. Some #COVID19 data collection for the win, wouldn't have been possible without the dedicated Explorer crew and help from @ONresources!

@GLATOS_Fish Director Emeritus Dr. Charles Krueger discusses how telemetry is being used to address management needs in the Great Lakes and Midwest, check it out! Please RT

Thank you so much to @RAEON_ @LeadleyTodd @DonUzarski @fisk_lab Matt Anderson, Katelynn Johnson and Neil Porter! Buoy retrieval success!

Some pics from fieldwork earlier today in a brook trout steam west of Peterborough. Thanks to @RAEON_ for the temperature loggers.

Underwater robots help Great Lakes scientists collect data during pandemic
By Sarah Scheili University of Windsor. While COVID restrictions have made scientific fieldwork in the Great Lakes difficult, researchers at the University of Windsor have continued to gather vital data using an underwater robot. Researchers at the Real-Time Aquatic Ecosystem Observation Network (RAEON) have worked with partner institutions in the United States to deploy an ...

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, – 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 ...
