Isolation of Microorganisms from Salt Lakes in the Dry Valley, Antarctica, and Their Living Environment
Isolation of microorganisms and determination of gases dissolved in waters of unfrozen salt lakes in the Dry Valley of Antarctica were carried out, as part of the Dry Valley Drilling Project (DVDP) of the Mc-Murdo Sound region during the 1974-1975 summer season. Samples were collected in and around...
