FERRO participated in the Global Lake Ecological Observation Network (GLEON 2025) Virtual Meeting, held online between 28-29 October 2025, an international forum dedicated to the study and management of lakes and their role in global biogeochemical cycles. The event offered a platform for researchers and practitioners to share the latest scientific findings, discuss monitoring and restoration strategies, and explore the ecological and climatic implications of freshwater systems.

Partners from SDU attended the meeting, presenting an abstract authored by Emma Polauke and Theis Kragh, titled “Methane Production, Oxygenation, and Flux Patterns: Snapshot Analyses in a Shallow Hypereutrophic Danish Lake.” The study investigated methane dynamics in a small, shallow, nutrient- and carbon-enriched lake, examining spatial variability in sediment methane production, surface fluxes and oxygenation patterns. High-resolution summer “snapshot” campaigns between 2022 and 2025 revealed significant horizontal and vertical gradients in methane dynamics, despite the lake’s morphometric uniformity. The results highlighted the influence of sediment nutrient content on methane production, the role of oxidation in surface waters, and the sporadic release of methane through ebullition, offering key insights for the design of effective lake restoration strategies aimed at reducing greenhouse gas emissions.

The abstract and related findings were shared in the GLEON 2025 poster and abstract book, contributing to broader discussions on freshwater management and climate mitigation. FERRO’s participation emphasised the project’s commitment to integrating scientific research into practical restoration solutions, promoting knowledge exchange and collaboration within the international limnology and water management community.
