Paper Abstract

A method is developed, and tentatively tested using a single example, for using the different wavelength dependencies of variations in incident daylight and the diffuse attenuation coefficient of seawater to estimate fluctuations in incident irradiance at the surface during profile measurements of spectral irradiance, and to correct the profiles accordingly. Smoothed estimates of downwelling irradiance and its vertical derivative are obtained at 10 m intervals by fitting cubic Hermite polynomials; these values for 6 wavelengths are then combined to estimate the surface irradiance, its rate of change, and the diffuse attenuation coefficient.
