Abstract

The Undulating Oceanographic Recorder (UOR) Mark 2 is a self-contained, depth-undulating, oceanographic sampler, which can be towed on an unfaired steel cable at speeds from 3.5 to 13.5 m.s^-1 and is independent of the vessel for any services other than towing facilities. The UOR carries a suite of electronic sensors for temperature, depth, chlorophyll concentration and downwelling and upwelling solar radiant energy (broad band 400-700 nm and narrow band 445, 520, 550 and 670 nm). Sensor measurements are recorded in situ by a digital tape recorder. Data are presented for measurements in the western English Channel, in the summer of 1984. The data provide attenuation coefficients for sea-water and chlorophyll at each wavelength and sub-surface reflectance ratios at each wavelength from which algorithms are developed, relating reflectance ratios and chlorophyll concentrations. The results are in close agreement with values reported by other workers, using conventional sampling techniques of optical oceanography.
