The current signal-to-noise ratio (SNR) as a function of wavelength given various SNR cases, where 1.0 is the default ocean color scan time requirement of 0.763 s. A factor of 0.7 would reduce the SNR to 400:1 from 650 to 700 nm, sufficient for the presence and absence detection of oil films and Sargassum. A doubling factor of the scan time increased SNR for low signal water quality events or to reduce observation uncertainty.
