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.

Spent the morning planning exciting glider missions for 2020 & getting aquatinted with two of our recently delivered G3’s. Now to name them.... any ideas? 🤔

The holidays arrived early for us with these new VR4’s from @vemcoteam 😍

Watch the lakes turn cold!

Modeled temperature data is available on the Portal:

From NOAA CO-OPS operational forecasting system model and @NOAA_GLERL

Some more details on ErieWatch and @RAEON_, and how these programs are connected with others in the Great Lakes

Chilly day for a probe extraction, but I think I got off easy compared to the weather my colleagues faced over the past few weeks. Thank you @RAEON_ for all your amazing work!

4 new @RAEON @fisk_lab buoys hit Lake Erie this year, and showed up on GL Buoys!

The Real-Time Aquatic Ecosystem Observation Network is doing some really exciting #obs work, and we're stoked to help manage that data.

Kind of spooky on Lake Erie today 👻 Another successful retrieval of @ErieWatch buoy.. they seem to keep getting bigger 🤔

4 months in #LakeErie ... those zebra mussels sure didn’t waste time covering this buoy and receiver. #trackingnotslacking #telemetry #fieldwork

Taking every opportunity for calm weather on Lake Erie we can. Thanks to our amazing team yesterday!

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 ...
