Spectral Properties of Some Marine Phytoplankters

The spectral properties of some marine phytoplankters have been obtained in the visible (400–700 nm) region of the electromagnetic spectrum. From those data the colors of the phytoplankters (dinoflagellates and diatoms) were calculated using standard C.I.E. techniques. The color-matching functions used x̄, ȳ, z̄ were the 10 ° field-of-view functions of 1964. Use of these functions better approximates the color as seen by a normal observer than those of the 2 ° field-of-view functions. The spectral transmittance of each of the samples were derived from their absorption spectra. These spectra were observed on a Beckman DK-1-A spectrophotometer, using the method of Emerson and Lewis as modified by Yentsch.⁷ The colors were found to lie within the same area as those of plants measured by Gates, Kagan, et al.³
