Extended Data Fig. 2: Predictions of a null model in which the vibrational modes of H2O are ignored.
From: Vibrational modes of water predict spectral niches for photosynthesis in lakes and oceans
a, In the null model, the absorption spectrum of water (blue-grey line) is replaced by a smooth absorption spectrum (magenta line) without the subtle shoulders of the vibrational harmonics. b, Overlay of 100 underwater scalar irradiance spectra at the euphotic depth for waters with different CDOM concentrations, calculated by the null model. The null model does not predict a spectral landscape with pronounced peaks and valleys (in contrast to models that incorporate the vibrational modes of H2O; see Fig. 2 in the main text).
