Water temperature influences most physical and biological processes in streams and, along with stream flow, is a major driver of ecosystem processes.

Monitoring stream temperatures can help researchers quantify a stream’s relationship to terrestrial and aquatic ecosystems. While many stream temperature monitoring protocols exist, most are written for aquatic specialists. In a new USGS report, USGS and National Park Service scientists provide precise and easy-to-understand stream temperature monitoring protocols for non-specialists. The protocols include instructions for using a specific brand of data loggers (Onset), including launching, checking factory calibration prior to field use, installing in streams for year-round monitoring, downloading and retrieving from the field, and inputting project data into databases.
