Cooperative Agreement for CESU-affiliated Partner of the Cooperative Ecosystem Studies Unit

The USGS Water Mission Area (WMA) Next Generation Water Observing System (NGWOS), is offering a funding opportunity to a CESU partner for a laboratory evaluation of a multi-parameter standard solution for water-quality analysis.  The standard solution, recently patented by the USGS (US 11,768,160), is a combination of a xanthene dye, distyryl biphenyl (DSBP) and a pH buffer that is intended as a quick, easy, and stable standard solution for the verification and/or calibration of field sensor performance.  The standard solution can be used to calibration several field sensors at once including sensors for fluorescent dissolved organic matter (fDOM, e.g. excitation at 350 nm and emission at 450 nm) and chlorophyll-a fluorescence (excitation at 465 nm and emission at 665 nm).
