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.

Evaluating Microbial Nutrient Sediment Dynamics in Lake Erie Watersheds
A primary goal of water quality managers is to intercept or mitigate nutrients or pathogens at their source to ensure effective wastewater treatment. Source water…
Investigating Fish Connectivity in the Rideau Canal Waterway to Inform Conservation Decisions
By: Jordanna N. Bergman, PhD Student, Carleton University and Steven J. Cooke, Professor, Carleton University The Rideau Canal Waterway, located in eastern Ontario, forms a…
Evaluating stationary hydroacoustics for determining fish movement and abundance
Little is known about the large-scale movement patterns of Great Lakes fishes. Though it is understood that large migrations of fish typically occur along regions…
Black Bay Walleye Acoustic Telemetry
Located on the north shore of Lake Superior, Black Bay historically supported a robust commercial and recreational fishery for walleye (Sander vitreus). Unfortunately, the walleye…
Using the REASON (River Environment And Sensor Observation Network) Project to Support Adaptive Management of the Saint Lawrence River
A regional water problem is the paucity of data to support policy decisions on water quality in the International Section of the St. Lawrence River.…
Monitoring flood water in the Detroit River
Great Lakes water levels have reached record highs in 2019, eroding shorelines, threatening and damaging public/private infrastructure (e.g., marinas, homes and cottages), and overwhelming water…
Modelling of nutrient inputs into Lake Erie using real-time instrumentation
Harmful algal blooms are a major concern in large waterbodies and have historically been linked with high phosphorus inputs. In Lake Erie, while extensive watershed…
Validation of NOAA-GLERL and U Michigan-CIGLR Hypoxia and HABs models in Lake Erie
Photo credit: Ed Verhamme During early summer and fall of 2019, RAEON deployed three real-time buoys equipped to measure weather and water-quality parameters, including dissolved…
