Abstract

An underwater spectral radiometer has been designed and field tested to measure the in situ apparent optical properties of ocean waters from 400 nm to 800 nm. Light from scalar and vector collectors sensitive to upwelling and downwelling irradiance in the marine light field is relayed locally by fiber optic cables to the slit position of a sealed spectrometer. By simultaneously measuring the upwelling and downwelling scalar and vector irradiances at two depths the system becomes impervious to changing ambient light levels and requires relative rather than absolute calibration of its collector/sensor sensitivities. Capable of descending to 100 meters, the spectrometer images up to ten spectra from the marine environment with 5 nm spectral resolution simultaneously.
