This paper describes a new submersible instrument which makes simultaneous measurements of chlorophyll fluorescence, beam attenuation and wide-angle scattering using a single xenon flashlamp as the light source. Cross-calibration against single-parameter commercial instruments shows satisfactory linear correlations, comparable resolution and enhanced dynamic range. The instrument package includes microprocessor control of data acquisition and a rechargeable battery pack. It is capable of acquiring high-resolution vertical profiles when deployed from a ship, or bio-optical time series from moorings. Results are presented here from initial deployments in inshore waters and in a deck tank at sea.
