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.

RAEON EDI STATEMENT

Following the leadership of The University of Windsor, RAEON is equally committed to ensuring that researchers involved in the network are provided with an equitable, diverse, and inclusive (EDI) environment.

@RAEON_ @CIGLR_UM @USGS Late posting, but here is the @TeledyneMarine Sturgeon being retrieved from #LakeOntario Monday by our @uofg co-op student Eve. #gliders

🌊🌊 Big waves at several buoys yesterday and today.

A few to watch right now:

Alright this may be our favorite video yet. From the #LakeMichigan #MichiganCity buoy, 45170, September 22, 2021 around 10 am Central Time. Serious dramamine warning. This is not a drill.

All hands on deck for glider ops! Yesterday, @CIGLR_UM and @USGS deployed Mary Lou in Hammond Bay for acoustic telemetry range tests. For a few hours, we had three RAEON gliders in three different Great Lakes 💪🏼 before recovering Sturgeon from Lake Ontario after 2.5 weeks.

NEXT, we drove home to prep the #glider for #LakeErie! What an amazing team effort on piloting the glider with @RAEON_ & vessel support by @michigantech. Learn more about our #GreatLakes #ObservingSystems research: https://t.co/NzOf5vDSqw

Our deepest condolences to family, friends and the @GLIERUWINDSOR @EESWindsor community on the loss of Dr. Jill Crossman. We'd like to share a video featuring Dr. Crossman so that you can learn a bit more about her and her work. https://t.co/4wkj1i2biN

Another glider launched in @LakeErieNorth. Thanks so much to @CIGLR_UM + @ohiodnr for their amazing efforts. Cormorant will be working to verify lake turnover throughout the next few weeks!

#loonranger is refurbished and back in the water, ready for field work on Lake Erie!

It's Wiggle Wednesday! One of the standard pre-deployment checks for our gliders is to have them "wiggle" for 10 minutes, which tests that the mechanical components are functioning as expected. #wiggleon #wiggleoff

Big load of PIT tracking gear just arrived... funding from @RAEON_ I am excited... my wife is less so as our garage is now lab equipment depot! @AndreasEkstrm2 @WTwardek @CarletonScience

A win some, lose some kind of week- or more accurately, "find some, leak some." The RV Blue Heron crew found a set of our sensors lost during a storm weeks ago (hurray!) but our Lake Ontario glider, Daphnia, had a small leak in its science bay. So it goes in aquatic science 🌊

Thank you Dallas and Kelly! Here’s hoping for a quick turnaround 😅

🚨We're Hiring!🚨 PLZ SHARE!
