fDOM

detects the fluorescent component of DOM (Dissolved Organic Matter). The measure or fDOM is commonly referred to as CDOM for chromophoric or colored organic matter but we choose to use fDOM because it is a more specific descriptor or the sensor and differentiates it from other measures of CDOM such as absorption. The fDOM sensor uses a UV LED for excitation (370nm) and detected the fDOM fluorescence at 460nm.  The sensor is extremely sensitive and provides quality data on the relative change in fDOM concentration over time and/or space.
