Definition | A submersible double-flash pulse fluorometer for continuous, in situ measurement of chlorophyll fluorescence parameters. It contains two excitation channels and one emission channel. One of the excitation channels provides a weak, probe flash used for measuring the fluorescence yield of Photosystem II (PSII). The other excitation channel provides a pump flash which is used for closing the reaction centres of PSII. Both excitation signals are generated by xenon flash-lamps. The light from the flash-lamps is collected by condensers and by a set of bluegreen excitation filters. The emission signal is collected by the emission condenser and filtered by a red filter before striking the photodetector. The instrument operates over a chlorophyll-a concentration range of 0.03-50 ug/l and has a depth range of 200 m. The excitation wavelength range is 400-550 nm and the registration wavelength range is >680 nm. The instrument was developed by the EcoMonitor Laboratory of the Moscow Institute of Engineering Physics and was used during the 1990s. |
