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.

Anyone have exciting weekend plans?

While at the @ROMtoronto, @c_cailin saw a familiar robot. Nice Slocum glider at the Great Whales exhibit, @OceanTracking & CEOTR! Very cool opportunity to learn about using gliders to study & protect endangered North Atlantic right whales.

CHALLENGE: I'll personally donate $1 for every like and $2 for every retweet. Ready! Go! https://t.co/78AsQOooNY

I was also impressed by all the kit @RAEON_ has for measuring conditions in Great Lakes

What can smart technologies offer to improve our understanding, management, and use of the Great Lakes? @spaikin speaks with @fisk_lab (@GLIERUWINDSOR), @MarkPFIsher (@cglrgreatlakes), @glos_kpaige (@RealGLOS) & Barbara Moktthewenkwe Wall (@Trent_TSE) | Producer: @Mariasarrouh

Tune in to listen to our Science Director, Aaron Fisk + colleagues discuss #smartgreatlakes

Who else is attending @OceanTracking's annual symposium?🙋
Great opening remarks and discussion so far.

Catch us tomorrow at 12:20pm ET for the 2020s of Telemetry panel, as @c_cailin outlines how we are using gliders for acoustic telemetry applications in the Great Lakes.

Along with our Lake Erie field season, we wrapped up Great Lakes glider operations last week with a final recovery out of Lake Ontario. Our last mission was a stormy one but Sturgeon persisted! Now, time for winter maintenance and some exciting upgrades for the glider fleet.

That’s a wrap for the 2021 Lake Erie field season. Thanks to everyone involved for their hard work! We deployed 7 real-time buoys, 4 ADCP’s, and countless water quality sensors as part of an @NSERC_CRSNG alliance water security project. Until next year!

So glad to have @c_cailin of @RAEON_ join us on the @RV_Cisco yesterday to retrieve our last collaborative @FishOceansCAN #AUVglider #LakeOntario 2021 mission. Four successful deployments this year ✅. Lent a hand with final near-offshore plankton sampling too😀 Now to plan 2022!

Happy Halloween from Lake Scientist! 👻🎃https://t.co/HHS4DwP1fB

Our team has been busy pulling buoys out of @RealLakeErie for the season. This fall weather always presents a challenge but we are getting it done! Great work so far 👏 Check out that biofouling!

Our glider pilot, @c_cailin shares some of the unique challenges of operating gliders in the Great Lakes during the Underwater Glider User Group (UG2) Webinar today. Who doesn’t love a good challenge in science? 😆

We're @MichiganStateFW @GLATOS_Fish recruiting a Post-Doctoral Research Associate (fixed term) to evaluate spatially-specific mortality components from acoustic telemetry data. Incumbent will work closely w/ academic and management partners.

Please RT

😍 bring on the data!

It's been an exciting season working with @DFO_Science! Collaboration has been key in making these missions happen. We've learned a lot from gliding in Lake Ontario and will certainly build on the knowledge (and data!) we've gained 🍁
