Fig. 2: Predicted and observed planar irradiance spectra under sea ice at three different locations.

a Central Arctic Ocean, b Baltic Sea, and c McMurdo Sound, Antarctica. Observed spectra (dashed lines) in (a) and (c) are from Lund-Hansen et al.2 and in (b) from Kari et al.34. In each panel, the measured chlorophyll-a concentration in the ice (chl-aice), ice thickness (zice), and coefficient of determination (R2) between the predicted and observed spectrum are indicated. Predicted spectra (solid lines) are based on Hydrolight-Ecolight 6.0, using the input data in Supplementary Fig. S1 and Supplementary Table S1.
