Installation Matters: Implications for In Situ Water Quality Monitoring

نویسندگان

چکیده

Novel in situ sensor technologies can measure water chemistry at high temporal frequencies, yet few studies have evaluated how installation affects measurements. In this study, we assessed the effects of commonly used protective housings on readings. Working two mountain streams, colocated specific conductance sensors four different housing types that varied openings for exchange (mesh, screen, holes, and open). We compared measured values through time performed repeated salt tracer additions to evaluate influence type calculated discharge. Sensors readings mesh and, a lesser extent, screen frequently diverged from with larger (i.e., holes open), indicating reduced between stream housed sensors. Further, recorded more damped delayed response other housings, resulting markedly discharge values. From these findings, recommend should be deployed large sufficient exchange.

Fundamentals of in Situ Digital Camera Methodology for Water Quality Monitoring of Coast and Ocean

Conventional digital cameras, the Nikon Coolpix885(®) and the SeaLife ECOshot(®), were used as in situ optical instruments for water quality monitoring. Measured response spectra showed that these digital cameras are basically three-band radiometers. The response values in the red, green and blue bands, quantified by RGB values of digital images of the water surface, were comparable to measurem...

Limnology, Liistiuci of Keewatin, N.w.t.: Implications for Water Quality Monitoring in the Nortii

Geochemical studies and surveys conducted by the Geological Survey of Canada have provided considerable information about the natural geochemical variations in glacial drift, lake sediments, and lake waters in south-central District of Keewatin. In addition to their intended contribution to mineral exploration, these activities yielded much basic background data that may be applied to the plann...
