We measured in situ photosynthesis of benthic microbial mats at various depths in Lake Hoare, a permanently ice-covered lake of the McMurdo Dry Valleys, Antarctica, using oxygen (02) microelectrodes. We further investigated the vertical distribution and activity of pigments in the microbial mats usi...
