Abstract

An in situ fluorometer has been designed to determine the concentration of a bacterial-sized photoautotroph. The concentration may then be used to estimate their effect upon optical properties in the upper ocean. Their fluorescence signal at 575nm enables assessment of their natural abundance fluctuations. The fluorometer is designed to be used in profiling and in moored modes. Such an instrument can provide valuable information necessary for improving our understanding of the dynamics of bacterial-sized microorganisms within the particulate matter in the upper ocean.
