This research study investigates a method of employing a subsurface radiance sensor to collect underwater radiance time series data for use in indirectly deriving surface wave height power spectral density estimates as a function of frequency. Ocean surface wave height time series data is collected by a conventional resistive wavestaff and underwater radiance time series data is simultaneously collected by an experimental subsurface radiance sensor. The data from each sensor is processed to yield power spectral density estimates. The power spectral density functions are presented for visual comparison. Normalized cross-correlation functions and coherence functions are derived and presented. A transfer function is derived to convert underwater radiance spectra to surface wave height spectra.
