The SentinelSpringS project aims to establish cost-effective, inclusive, and sustainable monitoring and modelling solutions to preserve the crucial role of springs in supporting vulnerable ecosystems that depend on groundwater. Key research questions include addressing the lack of long-term and real-time monitoring data through standardised data collection protocols and characterising the sustainability of spring-dependent ecosystems. Here we introduce efforts toward a new European onshore and offshore spring information platform and map viewer enabling open access to real-time monitoring data on spring quantity and quality potentially including geogenic elements and relevant pollutants such as nitrate and pesticides. The information platform can encompass data on the impacts of emerging contaminants, water over-abstraction, land use change and invasive species on spring water chemistry and the characteristics of biological communities. Additionally, it contributes to assessing the influence of climate change on spring discharge and nutrient loadings, highlighting critical knowledge gaps in understanding climate-related vulnerabilities in spring-dependent aquatic and terrestrial ecosystems. The spring information platform will enhance our understanding of the hydro-ecological functioning of springs and aquatic ecosystems and their vulnerability to temperature changes and the broader impacts of climate change.
