Friedmann Valley
Friedmann Valley is one of the McMurdo Dry Valleys, located west of Rector Ridge at the head of Beacon Valley, in the Quartermain Mountains, Victoria Land, Antarctica. It was named in 1992 by the Advisory Committee on Antarctic Names after E. Imre Friedmann, a biologist at the Polar Desert Research Center, Florida State University, who in virtually every austral summer, 1976–87, led United States Antarctic Research Program field parties in the study of microorganisms in rocks of the McMurdo Dry Valleys. His wife, Roseli Ocampo-Friedmann Roseli Ocampo-Friedmann (November 23, 1937 – September 4, 2005) was a Filipino-American microbiologist and botanist who specialized in the study of cyanobacteria and extremophiles. Her work has been cited in work exploring the terraforming o ..., was a member of the field party in the last four seasons.

McMurdo Dry Valleys
The McMurdo Dry Valleys are a row of largely snow-free valleys in Antarctica, located within Victoria Land west of McMurdo Sound. The Dry Valleys experience extremely low humidity and surrounding mountains prevent the flow of ice from nearby glaciers. The rocks here are granites and gneisses, and glacial tills dot this bedrock landscape, with loose gravel covering the ground. It is one of the driest places on Earth and has not seen rain for nearly two million years. The region is one of the world's most extreme deserts, and includes many features including Lake Vida, a saline lake, and the Onyx River, a meltwater stream and Antarctica's longest river. Although no living organisms have been found in the permafrost here, endolithic photosynthetic bacteria have been found living in the relatively moist interior of rocks, and anaerobic bacteria, with a metabolism based on iron and sulfur, live under the Taylor Glacier. The valleys are located within the McMurdo Valleys Antarc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
