Spectral downwelling irradiance in an antarctic lake


, : Spectral downwelling irradiance in an antarctic lake. Polar Biology 7(3): 145-152

Spectral downwelling irradiance (400-700 nm) was determined in the ice-covered Lake Hoare located in the dry valleys near McMurdo Sound, Antarctica. Full waveband PAR beneath the ice was < 44 .mu.E .cntdot. m-2 .cntdot. s-1 or < 3% of surface downwelling irradiance. Maximum light transmission just beneath the 2.6-4 m ice cover, which contained sediments and air bubbles, occurred between 400-550 nm. In the water column below, attenuation of light by phytoplankton in the 400-500 nm region and between 656-671 nm suggested absorption of light by algal pigments.
