Cover Story: Underwater optical wireless communication (UOWC) has gained importance with the rise of unmanned underwater vehicles, particularly in offshore industries focused on sustainable food production and energy security. UOWC supports high data rates and low latency for video transmission; however, links are influenced by inhomogeneous light attenuation and sunlight. This study models the underwater spectral light distribution across depths in eight stratified oceanic water types, exploring optimal transmission wavelengths for maximum signal-to-noise ratio (SNR). We challenge the assumption that the blue-green spectrum is always ideal, revealing a unique relationship between wavelength, SNR, and depth. The results have implications for solar discrimination and routing strategies in optical wireless networks in the photic zone. View this paper
