The state of winter limnology in the Great Lakes

Earlier winter runoff correlates with lower summer phytoplankton biomass in temperate lakes, suggesting winter conditions set the stage for summer productivity.

A new collaborative network aims to fill the massive data gap in winter research across the Great Lakes through coordinated sampling and shared infrastructure.

Partnerships with the U.S. Coast Guard enable critical winter sampling in Lake Erie, providing unique data on a low-ice future when agency monitoring pauses.

Dominique Rumball investigates groundwater quantity and quality, focusing on nutrient transport and climate change impacts in the Great Lakes basin.

Continuous winter monitoring in Lake Erie reveals shifting metabolic states and CO2 fluxes, offering a glimpse into the lake's future low-ice conditions.

Winter ecology demands resilience and flexibility, as seen in the comeback of cisco populations in Lake Ontario and the challenges of fieldwork in freezing conditions.

Winter conditions drive divergent activity patterns in fish species, promoting coexistence in ways that shorter winters due to climate change may threaten.

Jana Levison evaluates the effectiveness of restoration projects for fish species at risk across Southwestern Ontario as part of the FishCAST program.

A Russian-Swiss interdisciplinary project reveals how under-ice convections and ice quality drive ecosystem development and carbon emissions in Lake Onego.

Deep-water fish like round gobies and alewives migrate significantly between seasons, with winter diets and behaviors differing sharply from summer patterns.

With ice cover declining rapidly, the scientific community must urgently coordinate winter research to understand climate impacts before the data is lost forever.
