Chlorophyll Fluorescence

Fluorescence is an optical effect where light is emmitted by something that has absorbed light. In the ocean, Chlorophyll-a fluorescence can be used as an indication of phytoplankton abundance via this estimate of how much Chlorophyll is in the water. CDOM (Coloured Dissolved Organic Matter) can also be measured using fluorometers.

OceanLab has several Chlorophyll-a (Chl-a) fluorometers (click here for equipment overview) that are recorded as auxhilary parameters on some of the CTD instruments. Chl-a 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.
