Abstract

A compact, rugged and portable white light optical fiber fluorosensor capable of giving real time measurements of marine phytoplankton populations of 0.1 (mu) g/l is reported. The excitation light is amplitude modulated and a phase sensitive detection system is employed. Results from a series of sea trials of the system in the North Sea during June 1993 have shown that the system is relatively insensitive to down welling light, has long term stability and does not suffer from fouling. The results from the system are shown to compare favorably with results obtained by conventional phytoplankton sampling methods.
