Paper Abstract

We have studied temperature dependent changes of the absorption coefficient of pure water at several wavelength bands in the visible portion of the spectrum. A WET Labs Inc. nine wavelength absorption and attenuation meter (AC-9) was used to measure the absorption coefficient. We found the largest temperature dependence (0.0034 m-1 degree(s)C-1) at the longest wavelength tested (715 nm). The temperature dependence at shorter wavelengths was less than a third of that observed at 715 nm. Because of the experimental arrangement we believe that the figures obtained represent the upper bound of possible values for the temperature dependence of the absorption coefficient.
