Events and Trends
MOSES is a new observing system of the Helmholtz Research Field "Earth and Environment" that investigates the evolution and impacts of highly dynamic, often extreme events using a systemic monitoring approach. By quantifying energy, water, nutrient, and greenhouse gas fluxes during short-term events such as weather extremes, abrupt permafrost thaw, or rapidly changing ocean currents, the system provides data to study potential long-term environmental impacts. Such event-oriented, yet cross-compartment datasets are necessary to better understand the impacts of climate change and develop adaptation strategies.

Where does the methane in the Wadden Sea come from?
In mid-September 2026, scientists from six German research institutions investigated this question in Meldorf Bay, where previous measurements found elevated methane levels in mudflats. The team investigated whether methane is produced in the mudflats’ sediments, carried in by groundwater, or transported from the mainland via drainage systems. MOSES was a partner in this joint campaign, which aimed to contribute to the improvement of greenhouse gas emission models and to support climate-resilient management of Germany’s vulnerable coastal ecosystems. The campaign was organized in close collaboration with several research projects: ElbeXtreme, Coast GEm, and AGRIO.
