Objective(s): To quantify the microbial constiuents as well as phytoplankton and zooplankton dominants in a range of high Arctic freshwater ecosystems; and to evaluate the exposure, sensitivity and resistance of these microbial communities to solar ultraviolet-B radiation.
Project Description: There is increasing evidence that levels of solar UV-B radiation have begun to rise in the high Arctic. Little is known about microbial life-forms in the ecosystems of Arctic lakes and rivers and their UV-B resistance. A sampling hole will be drilled in the lake ice. These samples of zooplankton will be studied by a microscope. Samples of water and periphytic communites will also be taken. Underwater solar radiation will also be measured.
