Abstract

Nowadays it becomes more and more necessary to identify suspended matter in oceans in order to increase knowledge about primary productivity as well as the transfer of contaminants or to discriminate toxic phytoplanctonic species. It has been demonstrated for many years that fluorescence can be a well suited method to obtain specific signatures of organic matter in the sea. The paper presented here describes an interesting design of instrumentation based on optical fiber use and multiwavelength analysis which will offer wide possibilities for in situ monitoring of algae. Combining the flexibility of optical fibers and video as data carrier, results show great promise for new oceanographic equipment. In addition to technical descriptions, responses of some different grown species like dinoflagelates or diatoms families will be presented and discussed.
