A chlorophyll sensor has been designed for remote applications in underwater-towed bodies and moored or buoyed sensor systems for measurement periods up to 60 d. The sensor has alternative ranges of 0 to 100 mg m -3 or 0 to 1000 mg m -3 chlorophyll a, with a resolution of 0.1 mg m -3, and excellent long-term stability of calibration. Some results obtained with the sensor in the Undulating Oceanographic Recorder in the English Channel are presented.
