Abstract :
An in situ fluorometer capable of operation to 400 m is described. A pulsed xenon light source ensures low power consumption (6 W) and a high signal-to-noise ratio, giving a phytoplankton chlorophyll a detection limit of 0.1 mg/m3. Operation at 8 knots in an undulator enables vertical profiles to be determined with a resolution of about 1 m. By changing the optical filters it is possible to detect the fluorescence of dyes, hydrocarbons, carbosol, etc., with similar high sensitivity.
