Deep-Sea CDOM Sensor

The deep-sea CDOM sensor employs fluorescence measurement technology. It excites colored dissolved organic matter (CDOM) in seawater using an ultraviolet light source, causing it to emit fluorescence signals at specific wavelengths. By detecting changes in fluorescence intensity, the sensor achieves precise measurement of CDOM concentration. This sensor can be integrated with mobile observation platforms such as buoys and underwater gliders, as well as fixed monitoring devices like moorings and ship-mounted water samplers. It enables multidimensional, high-precision observation of deep-sea profile CDOM concentrations, providing critical technical support for marine carbon cycle research and ecological environment monitoring.
