Low power gives many weeks of low frequency logging on a single charge.
Deployable alone or as an integrated intelligent instrument in moorings, profiling systems or as part of the payload of CI s towed vehicles. The optical head has dual sample chambers allowing comparisons to be made of ambiently-irradiated and dark adapted phytoplankton samples. The heart of the instrument is a special patented fluorescence excitation system capable of generating a train of excitation flashes at rates exceeding 200kHz. The fluorescence emission and flash excitation data are compared onboard, immediately providing fluorescence yield data which is used to calculate the biophysical parameters which pertain to photosynthesis. Later, the resulting data can be downloaded through an RS232 link from the FAST tracka to a host PC, where users can tailor the data stream to their experimental and analytical requirements.
