Modeled underwater light during Polar Night.
Underwater light intensity plotted as scalar irradiance (E o irradiance on a point from all directions weighted equally). Light values were derived from radiative transfer model results of diffuse skylight irradiance measured at Rijpfjorden, Svalbard (80° 37.79N 22° 4.14E) at solar noon on January 1...
