Description: 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).
