Abstract

High-resolution spectral scans of solar ultraviolet radiation (UVR) were obtained directly beneath the 4.0-5.0 m thick, perennial ice cover of Lake Hoare, South Victoria Land, Antarctica. Both UVA (320-400 nm) and WE (280-320 nm) radiation were detectable beneath the ice using a diver-deployed, underwater scanning spectroradiometer which permitted accurate measurement in the 280-340 nm range, while avoiding effects of surface shading and/or hole effects.
