Fluorescence is an optical effect where light is emmitted by something that has absorbed light. CDOM (Coloured Dissolved Organic Matter) is a component of dissolved organic matter in the water that can be measured using UV (ultraviolet) fluorometers. CDOM concentrations are often higher in rivers and coastal areas influenced by runn-off from land.
OceanLab has several CDOM fluorometers (click here for equipment overview) that are recorded as auxhilary parameters on some of the CTD instruments. CDOM sensors are installed on the profiling frame at the Munkholmen site, and on the the inside of the buoy (ca. 1m depth) at the Ingdalen site.
