Description: Das Projekt "Integrating automated water samplers into wireless sensor networks (WIRESAM)" wird vom Umweltbundesamt gefördert und von Universität Zürich, Geographisches Institut durchgeführt. In environmental sciences field locations are often remote, difficult - and at times dangerous - to access (time-restricted access). Sensor-logger units and water samplers, which record data automatically, can partly overcome these restrictions. For water samplers the triggering of the sampling is a core issue. Typically, the onset of sampling is initiated by a single on-site sensor (e.g. when reaching/exceeding a water level threshold). Up-to-date, water samplers have not been linked to each other or integrated in a sensor network (e.g. on-site water level sensors, off-site rain gauges and upstream water quality sensors). This project intends to integrate a suit of water samplers installed along a stream into a sensor network installed in the same catchment. This approach allows new possibilities of sampling, as the applied sampling strategy (e.g. triggering of the samplers) can be step-wise adapted, coordinated, and optimised based on online data generated by the catchment-wide sensor network. As a result of this project, water quantity sensor data can be linked to water quality sampling data on a new level, enabling scientists to implement sampling strategies based on online-interpretation of sensor data (e.g. by a hydrological or environmental model).
