hanging out live w/ @RAEON_ Glider Technician Cailin. I wonder what that beauty yelllow glider will look like after a tour of #LakeErie. Looking forward to all the cool data it will collect! #IAGLR21

Hurry over to our virtual booth at #IAGLR21, happening in just a few minutes! We have prize packs available for each day. To enter, simply attend our booth and chat with us. Mention us in a tweet for a bonus entry!

Tuning into #IAGLR21 from our glider lab @UWindsor! We are looking forward to a lot of great sessions. Come visit us at our virtual exhibitor booth today from 12-1pm (we have prizes)! @IAGLR

@michigantech @EddieGreatLakes @IJCsharedwaters Thank you to #IAGLR21 sponsors. Couldn't do it without you! @MichiganTech @IJCsharedwaters @NOAA_GLERL @CIGLR_UM @LampreyControl @GLIERUWINDSOR @msupress @RAEON_ AquaRealTime @FluidImaging Great Lakes Data Watershed @Innovasea @TheAEHMS

First of many field deployments for the @NSERC_CRSNG Alliance Lake Erie water security project. Featured here: water quality sensors that communicate with a central buoy (up to 1km away) to give us #realtime data. Oh & Science Director Fisk providing a hand in the field.

A fantastic day to begin 2021 field work! Real-time nutrient analysis re-initiated... #phosphorus #sourcetracking #sediments @RAEON_ @WeisenerLab @MundleLAB

Buoy season! Busy preparing for deployments in Lake Erie. Stay tuned. @Innovasea @RealGLOS @ScienceUWindsor

The Great Lakes are home to 20% of the world’s total freshwater, and a critical necessity to Canadians. @RAEON_ and @UWindsor have designed an early-warning system to protect water treatment systems in SW Ontario.

Listen to Dr. Aaron Fisk talk to @CBCWindsor's Tony Doucette about the $1 million invested in real-time data collection to protect drinking water. #algalblooms #lakeerie @RAEON_ @GLIERUWINDSOR @EESWindsor @UWindsorENG

Excited to support real-time data collection & protect drinking water in #lakeerie

$1 million invested in real-time data collection to protect drinking water. @UWindsor researchers using #data from #LakeErie to predict development of harmful algal blooms. @RAEON_ @GLIERUWINDSOR @EESWindsor @NSERC_CRSNG @UWindsorENG #cyanobacteria

$1 million invested in real-time data collection to protect drinking water

UWindsor researchers and their partners have received more than $1 million to deploy real-time continuous monitori...

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.

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 ...
