Abstract: Inherent optical properties, absorption and began attenuation were measured in situ using a reflective tube absorption meter at nine wavelengths: 412, 440, 488, 510, 555, 630, 650, 676 and 715 nm, in the Arabian Sea during March. Since inherent optical properties depend on the constituents of the water, these data were analysed with the pigment concentration and total suspended matter. The results are compared with those of other investigation using in-vivo methods. A non-linear relationship with Secchi depth was used to evaluate beam attenuation at 510 nm. Results of linear regression of beam attenuation at 490 nm with that at other wavelengths were found to be comparable with those reported by others for wavelength above 440 nm. Though the slope of regression increased from 715 to 440 nm a deviation with a decrease in the slope was noticed at 412 nm.
