Microbiology in the Dry Valleys: Lake Fryxell, Don Juan Pond and a dry algal mat from the vicinity of the Canada Glacier
Entry ID: K009_1979_1980_NZ_2

Abstract: Three main projects were undertaken in the Dry Valleys, a) a microbiological study of Lake Fryxell, b) a microbiological study of Don Juan Pond and c) a study of the reconstitution of a dry algal mat from the vicinity of the Canada Glacier. At Lake Fryxell the concentration of dissolved inorganic and organic carbon through the water column, the algal photosynthesis through the water column and the rate of incorporation of acetate into the microbial cells was studied. Sediment cores were taken for analysis. At Don Juan Pond attempts were made to examine the pond for bacterial growth. The dried algal mats from the vicinity of the Canada Glacier were rewetted with water and the effects observed.
