The optical characteristics of the upper ocean determine the primary energy input into both the physical and biological structure of the ocean. Absorption of solar energy heats and stabilizes the water, while a fraction of the absorbed energy provides the base of the marine food chain. Penetration of visible energy into the ocean as well makes possible a number of practical applications including bathymetry, underwater visibility, and penetration of laser signals. The measurement of optical properties from remote, untended platforms is therefore required for a range of applications, but presents unique challenges. Here, we discuss and review deployments of optical systems on untended platforms in the open and coastal ocean, and discuss successes, failures and recommendations for future work.
